92 sc2 vaccuum leak?

i think i may have a vaccuum leak. mainly bc midas told me so... they didnt put it on diagnostics yet bc i didnt wanna pay 80.00 quite yet.. the car is running so horribly and its pouring gas into my engine and not being consumed.. i went from filling up once a week to every other day now.. i did look around under the hood and there is a small amount of gas coming out where my header is bolted to the engine.. could that gasket cause all this trouble? my oil and antifreeze are fine so i dont think its my head gasket... also when i drive it will all of the sudden go from running crappy to running normal and idles super high for a second then slowly idles back down to normal then eventually within 3 minutes of driving goes back crappy.... i dont have a check engine light on but maybe my light burnt out?

If you have gas coming from your header then you have SERIOUS issues. WHy would you even drive the car like that? The header is HOT and can ignite fuel. Thankfully having gas at the header is not possible. But oil is. Your valve cover is leaking. Which also means it may be leaking into the spark plug wells. Replace the gasket.

Replace your ECTS. It has a two wire connector. I have posted a video for this before.

Clean your Throttle body also

A 92 will not kick a light till something is REAL wrong!!!!

When my temp sensor went I dropped from over 30MPG to under 23!!!! AND I had wacky idle speeds also. I would get someone else to eyeball it and see if there is realy gas pouring out, and if not, change that sensor first, and report back your findings.

As RC said its not possible. Take the throttle body off. Clean it with lacquer thinner or break clean. Clean the IAC valve. Its the one with the spring. The other is the TPS. You need a t20 torx and a 10mm to remove the throttle body. The throttle cable is easier to take off when you remove the TB first. Do not clean the TPS. Keep the piston of the valve and the spring pointed down as you clean it with CRC electrical parts cleaner and brake clean. If not the cleaning agents will get inside the valve and really mess it up.

ECTs can still go bad again. I would check the connector for corrosion aka green shit. If there is oil leaking out of the valve cover that too can cause a fire. It needs to be taken care of. Pull the spark plug wires out... if they have oil on them it's leaking... if they don't and there is some on the outside of the head... it's still leaking. Replace it. Take a picture if you need to. Post it on here for us to see what you are seeing. Most importantly.... TAKE OUR ADVICE!

Whoops.... didn't know you were two different people. Still cleaning the TB should be a maintenance.

sooooo.... replaced the ECT sensor... not the problem.. it started up rough- went smooth- back to rough again.... i did see two sensors in that general area one with one wire going to it.. could it be that??? oh and i cleaned my TB with TB cleaner and everything.... not it... :frown:

One sensor is for the PCM the other is for the Temp gauge. When cleaning the throttle body did you clean the IAC valve. Also did you check the connector for corrosion.

Next time you have hihg idle shut the car off and see if it goes away. If it does then you need to replace the tps with a OEM. Don't get aftermarket.
