Ok so the car does not exactly run like a champ while warming up. But it has sat for over three years before I rescued it so that is to be expected. However, once it hits operating temperature and the idle comes down to were it is supposed to be the idle is way rough. And if I drive it around the lot, the car dies when I hit the clutch to stop. I am thinking it may just be the raunchy gas that is in it. I am running a super high octane cocktail through it now. What does this sound like to yous guys?





Here is some info to help the diagnosis:



* No compression check has been performed.

* Air filter is new.

* Gas is nasty but getting better.

* Injectors "click" but I have not diagnosed them by checking the resistance.

* Fuel pump checks out good.

Have you checked the vaccum lines? I have found that these motors hate leaks. I had a hairline leak on mine and my car ran like crap. Your car sounds like Rotarymans, he has a HUGE leak on his and runs like how you describe it.

Are there any obvious places to check for vacuum leaks? I'm having the EXACT same ******' problem w/ my FC. Is there an easy way too check for vac leaks?

As far as N/A's go, i have no idea. I have a T2 and my leaks were always in a stupid place that you would never expect. At a race on night, my oil injector line blew off and I had no idea. Drove like crap until I decided to fix it. Thank good for premix .



The best places to look are at lines that are expossed to heat or movement. Your AFM can come loose, brake line, control valves, and everything else.

I know a good way to look for VAC leaks, I just considered all the hard stuff first!!!







Anyway, take a butane/propane tank with a torch nozzle or a reliable valve and barely open the valve. While the engine is running, slowy run the nozzle or valve next to your lines and junctions. When you find a leak your engine will surge to higher RPMs because of the flammable gas intake. I know I don't have to mention how damn dangerous this can be if you open the valve too much right?!? This is an awesome way to find VAC leaks but be safe and be smart.

Oh ****...thats a good idea. Never would have though about that. Thanks.

No Prob



I was impressed as hell when I first saw it too. When I was a young thug back in da hood...



Wait a minute! I am a skinny caucasian kid from Kentucky! What the Hell?!?

a can of carb cleaner will do the same thing, put the little straw on it and squirt controlled bursts around your vacuum hoses.

i would use the carb or brake cleaner trick and not the butane( just sounds safer)... mine did the same thing aftrer 3 yrs of sitting. did you change the fuel filter??? air filter..... check the TPS... new plugs and wires..... check the turbo for vac leaks... does the exh leak? check the TID they tend to crack at the back ( turbo side ). hope this helps you.... It did me....
