We start the '88 for the first time, but there is a problem...

[@yellowfoxbodyguy]

FIRSTI Sounded like mine after it sat for 15 years. You guys will get it tho!

[@urbanedgeautodetailing]

This is why static timing is important, if done proper the car will fire off in less then one full rotation. After doing heads and cam in my 89 Fox the car fired immediately 1st twist of key.

[@tobylynn75]

Love it. I just got my first foxbody 88 gt today.

[@emeraldnotch7758]

Welcome to the family!!!!

[@andytatro8466]

I would check compression and firing order

[@scott5.0hh44]

Never mind. Looked at it wrong. But does that cam have a different firing order?

[@TowGodEastBay]

NICE VIDEO , DO A CYLINDER DIFFERENTIAL PRESSURE LEAK DOWN TEST , IF SOMETHING IS NOT SEATED RIGHT OR BROKEN IT WILL SHOW UP RIGHT NOW , SIR

[@christhompson3500]

Mine sounded like that after I did the TF top end kit,It was wrong firing order

[@jeremyalbert2069]

check the info for the cam for a different firing order usually its a 351 firing order , also you may have a bad mass air meter or dirty meter causing pcm to drop cylinders or load cylinders . check compression on all cylinders and do a cylinder leakdown test maybe a leaking valve

[@RPJs-Cuisine]

I love ur doing a Windsor video! Caleb and crew are pros!!!! But damn, give me some olllllll skoooool sometimes. 👍🍺

[@spassmore8483]

im thinking you may possibly have a intake manifold to cylinder head leak on that cylinder ive had that happen before&same issues... good luck y'all keep us posted with a new video asap! love the build btw!!!

[@starbrightpools]

You guys have an injector testor, SOOO AWESOME!!!!

[@boostedsaleen6146]

All that throwing parts around and never once ran a compression test ...

[@birddog0347]

It MUST be a spark related issue, I'd bet the plug wire is bad and is shorting somewhere... swap wires and see if the problem moves with the wire. Also check the TFI module and make sure there's no MSD box or anything non-stock in the ignition system.

[@twinturbocoyoteftw]

And you also put the spout connector in while the engine was running which isn't the correct process. As you know the ecm moved the timing back to where it was previously. Spout goes in key off. Fyi this one has pushrods

[@josehernandez-ni9jm]

it'll be the last thing you check lol I hate that feeling, but you'guys wrll get it love your channel keep up the good work

[@twinturbocoyoteftw]

Sounds like the valve adjustment is off. You could definitely hear lower compression with the uneven cranking on the first start. You guys keep up the mustang resurrection process going on!

[@alecgriswold6440]

Definitely need to plug those heads in the back. had the same issue with mine, only they unscrewed themselves after a couple miles.

[@1fastford795]

I’m having a problem with my 88 gt car fires up fine but once it gets hot if I Turn the car off and try to start it just turns over and won’t start till it’s cooled of

[@jonyovanno4145]

I love that injector tester! Sweet deal!

[@GameOver321]

Nice work guys. Have a question. I'm possibly buy a 90 lx with a trick flow R upper kit. I know the work was done back around 1998 or 1999, would the heads say trick flow on them? They have the same exact valve covers as this 88. I see on this build there is a trick flow stamp on the front of the heads. I couldn't find that on the car I'm possibly buying. I just want to know what I'm possibly getting into. Thanks

[@chrisoverbey7232]

The machine shop that rebuilt my engine put a flat tappet cam in my 91 roller engine. Exact same symptoms as this. Changed it to the old firing order and it fired right up. I literally changed everything included the ECM before I found this out.

[@RPJs-Cuisine]

Throw another plug in that thing! Easy breezy!!! It happens, not often but does!

[@Riffs_Garage]

Put a air filter on to help smooth out the air entering the maf. That'll help stabilize the idle at least. Probably won't fix your misfire issue tho

[@Fast-lu6qu]

It's sounds like the valves aren't sitting 🤔🤔🤔

[@NorthernPerformanceGroup]

You should compression test it also check the spark plug to make Sure that you didn't crack it I had and issue with mine that I cracked a plug and you couldn't tell it was cracked only way I found out is because I had enough Grease on my hands I left a small black line on the spark plug in the crack

[@bearfoot25]

did you turn the engine over with the valve cover off to make sure the valves are opening and closing? I had a built older 302 that wiped out a lifter and cam lobe. it wasnt a roller but could be a collapsed lifter if they are hydraulic

[@michaelgraham2347]

Check fuel pressure n regulator if timing n firing order is good.

[@pagosplace3065]

Hey Foxcast, what kind of bottom end does it have and are you guys gonna put this on the Dyno?

[@scottroe1087]

I wonder if your valves and valve seals on that cylinder are still good? I'd say maybe a head gasket problem too but if compression was good I'd rule that last part out

[@jchammer1690]

It happened to me with a set of brand new Edelbrock E-street heads. That was my first guess

[@nashhernandez461]

I need to know whats the problem. I have the same issue on mine

[@boostedsaleen6146]

Messing with coyotes too long forgot about the pushrod. Lol

[@cyclonekevin6199]

I said the same thing.lol

[@JS-sc8nr]

Sounds like there's something going on with the cam. Like its wiped out on a lobe or something. Valve spring? Idk just some ideas

[@JS-sc8nr]

Rocker arm, bent push rod?

[@travisevans7502]

yes do compression test and leak down

[@ericdebisz9458]

I maf swapped my 88gt back in the dizay. Haven't been down this road. If it was a vacuum leak it have to be a massive one for it to dump that much fuel that quick, I mean this is 1st fire. I've only seen plus turn that soot black when it's a timing issue. I'd start fresh all over again. Bring her up to DTC on comp stroke, locate 1 on dizzy drop her in. Idk if you used the factory balancer again? If the outer ring with the timing marks head walked on the inner piece of the balancer, you will def have way off timing. I mean she's close. She does fire and rev. I can't hear any sucking/ vac noise over that X pipe to manifold leak. Best of luck. When in doubt coyote swap it. I mean that how this channel started right 😂

[@pjr6537]

compression check on that cylinder....make sure the valves are fully seating allowing proper compression. ive seen where brand new, name brand heads right out the box have a leaking intake, or exhaust valve/valve seat (wont name companies here). had to have em machined, smh! try another spark plug wire on that cylinder; old wire might give a resistance reading one way, then when "bent" back into place, the wire inside breaks connection...

[@e90_cris20]

Why did you spray water on the headers what does that check??

[@scottsigmon926]

Run a compression test and a leak down test

[@RUNINAGT]

Oh the love of aggravation with owning and building a Fox.. Keep at it. Hope the motor don't have to come out.

[@scervantes1982]

Looks to me like your map sensor is bad on the firewall . It’s a breathing problem it doesn’t compensate for the air . Just a thought .

[@GearHead704]

A Dook Blue Devil must have sabotaged you just like he did my basketball team this year 😁

[@dmh1367]

Check the firing order?

[@daveg9002]

Maybe replace the tfi module i had to do that to mine

[@FoxcastMedia]

Good guess for sure

[@Stangnotch03]

Timing off? Spark plug wires right?

[@happyinfidel1]

thats num 5 plug.

[@rosconole]

Toss BBK mass air in the garbage...Clean out IAC, Change wires, check your not a tooth off, unplug #1 see what happens. Could be vacume leak and gas goes bad so fast these days. I had to drain bowls on a carburetor many times to finally get water out of system one time. It ran like a dog like that.

[@fredbee850]

how can I get in touch with you to help with swap or where is the shop located so I can pay you for the swap want this in a mark iiiv

[@joshruby]

sounds like plugs wires crossed or maybe a non ho cam in it with old 302 firing order.

[@lancefoster2709]

It's nice to hear a pushrod motor cammin again!!! Lol

[@happyinfidel1]

Wires to the right plugs.. Num one is left side front.

[@nikkodnp]

MAF sensor needs a filter on it

[@HeadrushStudio21228]

Did you plug the thermactor holes

[@Fredness2300]

So it's not the massive exhaust leak in the collector on Bank 1 feeding oxygen to the O2 sensor making the PCM think it's lean? Huh...

[@Harry_Wagstaff]

Vacuum leaks cause all sorts or gremlins with those cars. Did you hear some intermittent hiss?

[@allenlane5018]

Check compression

[@frank3stangs]

Nice video! I think you have a bad #5 spark plug!

[@RPJs-Cuisine]

Is there a part 2 my cars doing the same thing

[@chadshue491]

Put the air filter on. Mine popped off and ran the same way. Give it a try.

The mass air is getting a faulty reading with so much air coming through.

Yes it does explain dead cylinder. Firing on wrong stroke

[@91frankenstang23]

Sounds like someone forgot to put the thermactor plugs in.

[@liftedjeep93]

91 Frankenstang I JUST deleted the egr in my 88gt.....run fine before, now acts just like this one. Egr block offs are in the back of heads! Be interesting in seeing what they find

[@91frankenstang23]

liftedjeep93 ya, I know this first hand. Did it myself with a set of twisted wedge heads. For the life of me couldn’t find out what the hell was leaking. Thermactor plugs on front and back of heads. Most accessories on front cover the holes, depends what ur running.

[@brssgarage90redmustang68]

If they did forget thermactor plugs they will never let us now cause they probably feel really stupid but thats what it sounds like to me

[@91frankenstang23]

Brs's Garage 90redmustang we shall see whenever they decide to drop another video.

[@timschneider7267]

Looks like you got valves not shutting all the way the only got one cylinder leaking

[@scottborkowski2411]

15426378 may be your savior. Had that on a 351W I built years ago idled for shit found out only 4 cylinders were firing when they were supposed to. Another head scratcher was a bad coil on the primary winding that made it idle rough with erratic miss fires.

[@markturner1951]

Put the plugs in the back of heads for the egr system👌🏻

[@adrianv8225]

Wanted to remove my egr but wasn't sure how to plug the back you say it fits fine with plugs ?if so that's perfect .I looked for egr block plate for my bbk TB but only found TB spacers disguised as egr deletes which goes in between the TB and intake manifold but that would still leave my TB open ?

[@sly50gt]

@@adrianv8225 some heads are threaded and fit an NPT plug, some heads you have to make a teardrop shaped plate and bolt it back down using the bolt hole for the egr tube mount (use 1/8" aluminum or steel and use the stock egr tube as a diagram of what you need to make) then clean the surface real well and seal it up with a thin bead of ultra copper silicone. theres plenty of egr delete plates for your throttle body and if not, make a plate just like you did with the back of the head and seal it up with ultra black silicone.

[@camaro3gen]

I would recheck the firing order.

[@jamiea2404]

What about those 2 brass fittings behind the throttle body with nothing attached, looks like a probable vacuum leak.

[@sly50gt]

those are for coolant to flow through the throttle body, completely dumb design and not needed.

Compression test and cylinder leakdown test, you have fuel and spark, i hate to say it but looks to be a compression issue.

yes I agree and most logical answer so far.
