This is the best TPI timing video on the entire interwebs!!! Live saving and absolutely money saving as well. Thanks a million. I cant begin to thank you enough for putting out such a detailed amazing video! Absolutely impressed!!!

[@AxlesGarage]

Thank you so much for the wonderful comment. It is appreciated.

[@robertcarlson6632]

Anybody that owns an Iroc , would know.

[@cbkidd]

I was doing a search and clicked on your video blog. I liked the way you took your time and go into detail. I like it so much I Subscribed. I hope you do a lot more videos on your Camaro. I also own a 88 iroc 5.7 liter. With 7,6330 org miles.Getting ready to get it running from setting for the last 10 years. Had spine surgeries so just starting to feel like I can maybe start working on her. Look forward to more of your videos.

[@AxlesGarage]

I appreciate the kinds words. We are currently doing a bunch of videos on the K5 Blazer, but have several planned soon for the IROC. Thanks so much for the comment.

[@billharris3049]

Impressive instruction...this will help many, me being one of them.

[@AxlesGarage]

Thanks for watching and the kind words.

[@jond1965]

Well done. Best video on this I have seen so far.

[@AxlesGarage]

Appreciate that

[@billbly1691]

I always enjoy your channel look forward to seeing your videos thanks

[@AxlesGarage]

I appreciate that!

[@jameshall4385]

vacuum leaks are a big cause of drivability issues with tpi cars. good luck changing the plugs. plan on doing them from underneath. it is the easiest way. you can get plugs 1,2,and 4 from the top. sometimes number 3 but just jack it up and do it from the bottom. i have had four third gens and that is the only way.

[@AxlesGarage]

Thanks for the heads up, not looking forward to that job.

[@cbkidd]

Hey, James Thanks for the tips on changing the plugs.

[@itsnodawayitustabe5654]

#6 and #7 are a crucible

[@milesmania1150]

Perfect. You did great. I am not a mechinic but I know a little and your right thiese cars are up and down with calibrations. Nothing is right but when it is.WOW

[@AxlesGarage]

Thanks 👍

[@ThePoison1]

I enjoyed your video but have 2 questions for you. I have an 86 Iroc Z28 with the 305v8 and TPI with HEI coil. #1) Is the timing set the same as with your 350 and regular coil setup (disconnect the brown wire?) #2) What is the base timing line for a 305 V8 engine?? Is it the same as for your 350 engine? Thanks and keep making these great videos for us.

[@AxlesGarage]

Yes, with the timing wire disconnected, the factory setting is 6 degrees BTDC. For your vehicle.

[@justinrovtar9798]

I have the same engine in my dad's 89 firebird. Great video 👍

[@AxlesGarage]

Thanks for watching

[@samstrolia]

Awesome video, thanks Axle!

[@davissunglasses]

I’ve got small hands and it’s still hard to get to that hold down on the 3.1. 15mm socket on a short ratchet from the drivers side.

[@AxlesGarage]

Thanks for the tip

[@kamranetemad4968]

Glad it was helpful!

[@KN1GHT2000]

Awesome man thanks!

[@AxlesGarage]

Glad to help!

[@hugegizmo151]

liked and subscribed good video thanks could you make a video on the tpi vacuum line and emission lines not a lot of videos on those

[@AxlesGarage]

We are trying to find a good vacuum schematic to figure it all out. All those vacuum lines are a great big pain.

[@bubbashadetree262]

I know I’m late for the party, but is there any problem with leaving the advance from the computer disconnected & giving additional initial advance- my 95 k1500 seems to run better without the computer advance

[@AxlesGarage]

Yes you need the computer advance., then you don't have the additional advance at speed. Traveling at speed under light to moderate load, the computer will advance timing for better fuel economy and stable temperatures.

I have a 1999 Camaro 3.8l... my car was driving fine then one day it just cut off wouldn't cut back on. I bought a new battery and drove for maybe 2 weeks then it cut off again. This time it just cranks no start though. Thought it was the fuel pump but I have a new pump so. What could it be?? When I first bought the car the check engine light would come on and go off some days it would stay one some days it wouldn't. Had it for about 2 months now it won't even turn on just cranks what's could this problem be?? My gas also hasn't been lasting that long I'll have a full tank go a couple places and it'll lose gas very fast

[@AxlesGarage]

Check fuel system, pump and pressure.

[@itsnodawayitustabe5654]

Could be coil.

[@frankpohr2764]

Great video! Very informative!

[@AxlesGarage]

Glad you enjoyed it!

Great info. Thank you!

Excellent, thank you.

[@AxlesGarage]

Glad it was helpful!

[@CPMest81]

I wish this video had come up back when I was learning how to do this, guess it didn't come up cause I was searching for 305 trans am lol

[@AxlesGarage]

Thanks for watching

[@jessievert]

Don't forget the knock sensor which is known for retarding the timing at times or need be as well

[@AxlesGarage]

Thank you

[@tinkertuff]

I have a custom wiring harness from Larry's electric and my tpi motor is in a 1972 chevy c10. I want to time it properly but I don't have the brown wire to disconnect. Any idea where that wire goes or what else I can disconnect to get timing right. I have it a 6 btdc without disconnecting anything.

[@AxlesGarage]

I would check with Larrys. You might really wake it up with proper timing.

[@tinkertuff]

@@AxlesGarage thanks. I found that I did have the wire got it timed properly. Turns out it had a bad injector. Got it replaced now it rocks and rolls!

[@AxlesGarage]

Great news

[@christianrichardson9244]

I have L98 also, which ignition kit would you prefer @ 200.00?

[@AxlesGarage]

All it needs is something basic. Spark/fuel/boom. Nothing fancy needed for a DD stocker.

[@davesmith2187]

My 50 firebird starts a lil slow n run a lil rough but is drivable then all of a sudden it runs like crap n won't go nowhere for 5 minutes then starts running fine again do u think i should check timing n chang the cap/ rotor?

[@AxlesGarage]

Gotta start with a solid foundation, Timing, tune-up etc is always good prectice

[@davesmith2187]

@@AxlesGarage ya i tryed that timing was about 6 new plugs n wires cap n rotor o2 sensor n fuel filter car runs ok when driving fast but when u slow down n drive slow it starts missing(loud banging) burns a lot of gas n smells like fuel i was told might b a cloged cat but idk if u think of ne thing i could use the help also checked the tps n has 5v at wot

[@johnd8773]

​@@davesmith2187what did it turn out to be?

[@ThePoison1]

I enjoy your videos,,, YES... They are a nightmare... hahahahahahaha lol

[@AxlesGarage]

Glad you like them!

[@xravenhairsexgod]

Curious, do you add a whole can or half can of Seafoam to your 5.0L crankcase before the oil change? And idle the engine for how long while Seafoam does it's job? Scored an '88 Z28 305 and will be a keeper.

[@AxlesGarage]

Seafoam: In Fuel approx 1oz per gallon of fuel to clean fuel system (I like to use it on a 3/4 tank and add a full can. Oil: Before oil change add 1oz per quart of oil. Run vehicle for several hours (I usually do it a day or 3 before an oil change.)

[@KN1GHT2000]

any news or updates or how its running now ? :)

[@AxlesGarage]

Correct timing and TPS adjustment made a tremendous difference. TPS Video here: kzbin.info/www/bejne/eH-0YWikqqmjhsU Then the master took a dump

[@Mitchues]

I have an 1986 z28 5.0 tpi the car is nothing but a pain in the ass ,no matter what you touch there is a reaction to something else. You cannot work on the engine everything is to close, I know what your saying about working on this pain..

[@FEDERALBOYSENTERTAINMENT]

What would cause it to backfire

[@AxlesGarage]

Timing way off

[@1980sSinaloense]

I took my 92 camaro to get smogged today and it didn’t pass due to this fucking issue with the timing 🤦🏽‍♂️

[@AxlesGarage]

Thanks for watching

[@wall4xxx]
