1992 F150 high idle fix

[@ahrenreinhardt705]

Awesome work. I got my 92 free from my sister but back when she had it, it had a screaming high idle regardless of temp. I ended up seeing the upper intake gasket hanging out in a couple spots. I removed that plenum and the gasket was crispy. Cleaned it all up and put a new gasket in and she idled great. The plenum (upper intake) gasket on the 5.0 is notorious for failing.

Thanks! 👍 Man, I love these trucks.

@@1186javierzuniga I just got done restoring a 95 4x4 for my son. Wrapping up a 70 Chevy 3/4 ton for him as well. Trucks are a great investment and can last a lifetime so long as you are willing to keep replacing what’s needed. I’ve got a long way to go on this 92 f150, but my next tackle is to eliminate the smog system.

This video helped me so much with my 1992 Ford F150 Flareside 5.0L. I was having similar issues. Thanks so much!

[@ydocproductions5593]

Great vid man! Even though the truck I’m restoring has the 4.9L I6 I’m gonna use the tips I learned from this video👍. It’s a cool truck!

[@1186javierzuniga]

Awesome!!! Good luck on the build!!!

I traded my Grand Marquis Colony park for a 1990 f150 a month ago difficult to start ran okay after watching many videos on timing and base idle decided to attempt timing adjustment without a light and after a few hiccups by some miracle today dialed it in and she starts right up everytime now to fix the miss 🎉

Wire brush your harmonic balancer and then paint it yellow or white and then tomorrow sand surface paint off . the groove's show up like crazy. 5 6 years now could still see mine fine

Going over my '93 f 150, just for giggles, I replaced the computer with one flashed in this century, i figured a 30 year old laptop wouldn't work so good, and they aren't that that expensive

[@bigjproduction898]

Interesting… would love more information.. I have a 1996 5.0l and need to tune it or upgrade the computer… what exactly did you do?

[@davekent4829]

The computer i think is about $150, it's under the dash above the driver's left foot, but you have to go under the hood to get it out, make sure you get the computer for stick, or automatic, they're different, don't ask me how I know,

[@MikeGarretson]

What was the second thing you changed after the iac valve

[@Beuwbsldurbdk]

That’s the Canister Purge Solenoid

Good video!.I have a question what did you replace for the high idle problem?

[@doubts72]

Hey man thanks For all the great work and fixes . Have you ever fixed the overdrive issue with these obs? I have a 95 Eddie 5.0 Bauer and I feel that it takes to long to shift or hesitant. I tried checking fuses ( they are all good ) I tried checking the abs box underneath the ash try ( people on forums said to unplug ) . I tried unplugging the battery for 30 min . I just ordered the speed sensor . Will update on that . Your help would be greatly appreciated!. Thanks in advance!

[@doubts72]

I ended up sending the PSOM to a company that rebuilds them and it fixed the OD issue and now my truck is shifting perfectly fine .

[@danielavila8629]

I have a question for you I have an f150 1992 and the reverse doesn't work when ot get had. Do I need to replace the transmission or is there any kind of band adjustments for this situation? . Thanks

[@danielavila8629]

When it gets hot .

[@1186javierzuniga]

Have u checked the codes? They have digital code readers for the OBD1 port under ur hood at the local auto parts place. Of u can do the paperclip trip. U might have a bad solenoid pack.

What is food to clean out injectors and how do you do it on a 1993 E150 Club Wagon Van 5.8l

[@1186javierzuniga]

I've made my own contraption looking at other KZbin videos where u get a tire stem, a small battery, some wire and carb cleaner. But u have to be careful bc that's highly flammable. Don't ask me how I found out... I'll see about sending u the link to a video.

Look up "Fuel injector cleaning without expensive tools".

[@na2000coma]

so my 94 bronco is idling very high unless i unplug the Idle Air control which Is new along with MAP, TPS , ECT, Distributer Cap, Wires, Fuel Filter, 98 Octane Gas and Air Filter.... Ive thrown every part youtube has told me to thro at it except the one at 9:13 .... What is that called?

[@1186javierzuniga]

That's called the purge solenoid. If ur still having high idle issues, have u gone through to check for vacuum leaks?

[@na2000coma]

@@1186javierzuniga I ran a smoke machine through the system and only place the smoke came out was the tps sensor area and the idle air top vent... I drove it today and now it won't even turn over so it's probably a bigger issue.

[@1186javierzuniga]

Any check engine light? U have a code reader? I bought one at my local auto parts place for like $20 and it's a digital code reader. Pre-1995 use an OBD1 code reader. These trucks will still give a code even if no check engine light is on.

@@1186javierzuniga I had some codes and the guy at the shop cleared the codes but they came right back. After I changed the TPS and the MAP they went off.

Hey im wondering if you can helo me out i have a 94 5.8 with high idle when the truck warms up and when in high idle the shifts are terrible any idea what it could be?

U have to have a vacuum leak somewhere. Make sure all of ur vacuum lines are not cracked/broken.

[@JESUSD6765]

I have a high idle issue, i replaced the iac and no luck

[@1186javierzuniga]

Have u checked for any vacuum leaks? U know how when the throttle opens up, it revs the engine? That's because the more air that's allowed into the in, the higher the engine will rev. That's exactly how a vacuum leak acts. It's allowing more air to go into the engine, thus making the engine rev higher (high idle).

[@JESUSD6765]

[@frankm8533]

My 96 4.9 will idle at 900 probably 90% of the time seems high then will kinda miss like it wants to cut out but only does it once a week for a couple minutes or if hitting the throttle in 2nd gear it acts real sluggish nobody can figure it out other then that its a great truck real clean

[@1186javierzuniga]

Man, that's weird. High idle is mostly associated with vacuum issues or an issue with the ECT sensor going bad. That sensor, when going bad, does all types of voodoo on these trucks. But seems like it's a vacuum issue to me bc when u hit the throttle in 2nd it bogs down, like if it's not getting enough or the right mixture of air and fuel to make it run right. I usually go to a pull a part yard and buy a hand full of sensors for cheap and test them on my truck with them. They'll run like $2 each. Or buy a new one sometimes for $45. (Get where I'm going?) The ECMs in the 4.9L trucks are known to go bad. Hit and miss kinda thing...

[@frankm8533]

@@1186javierzuniga Thanks for the info. I was also told try a MAP also. I just need to spend more time under the hood probably spray it down again look for vacuum leaks these old Ford have so much crap under the hood they don't need!

[@1186javierzuniga]

Yes they do, like the smog system. U can check the MAP sensor just by unplugging the vacuum hose. If there's a change in the RPMs, it's still good. Good luck...👍And let me know if u get it.
