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?
