Any check engine lights? Cats might be clogged, may need a tune up, did you change the fuel filter since you've owned it?

Matt94GT · Aug 29, 2006

Try Cleaning the maf sounds like a symtom of this for sure. Also clean your IAC.

When was the last time you did a tuneup? As in plugs, wires, cap & rotor?

jaystang98 · Aug 29, 2006

i already replaced the o2 sensors, fuel pump, fuel filter, spark plus, and MAF, it dosnt have cats, the check engine light keeps comming on for the 02 sensor and the is also a code for the imrc is sticking. and how do u clean the IAC????

Did you put a new set of plug wires on it.

Could also be fuel injectors.

I had a truck I was working on once, ran great untill about 1200 RPM's, then it would break up like a bastard. Turned out one of the fuel injectors had a broken spring inside, and could not handle the presures at higher RPM's.

Just a thought. I would try plug wires though.

yeah thats kinda what my car is doing

94gtstang50 · Aug 29, 2006

Def clean the imrc's, its easy and just takes time to do. The car will be a lot faster after you do this.

welp... fix it...

i have no idea wtf a control module is...

94gtstang50 · Sep 2, 2006

Did you try cleaning the carbon off first? Ford tech guy said I probably have to replace my imrc's and the controller box. It just ended up being a connection that needed some dieletric grease and some carbon that needed to be scrubbed off.

i did try it but i dont know how to take off some stuff like, how do u take off the coolant tubes, and how u take off the fuel rails, if somone could help me that would be cool

94gtstang50 · Sep 3, 2006

Coolant tubes: just pull them up and gently shake em back and forth to help them come out. Make sure you remove the 4 bolts holding them in first. Fuel rails: you'll need a special tool, like $9 at advance auto. There are also 4 bolts holding this bad boy down. Lift carefully and dont worry if some of the injectors get stuck on the intake manifold. Make sure you release the pressure in the rail too first. Just take your time so you dont make any mistakes. Where are you located at?

94gtstang50 · Sep 3, 2006

Damn, too far away to come over and help ya. We do have a few guys from florida that may live close to you.

Here's a link for you on how to clean the IMRC's
You can either clean them or just get a set of 4.30s and remove the IMRC's.
