    Anyone with a bad map sensor, fuel pressure regulator? sympt

    My 94 cuttlas sl, is not running like before, when its cold and i start it, i wont idle and the rpms go really low, and then back to normal, but it wonts stay in one place until the engine is warm, i changed the fuel filter and it didnt fix the problem, also when this happens and i try to take off, i hit the gas and it wont respond, it's like if the car was not getting enough fuel, and it wants to turn off, but it doesnt. The exhaust gases have a gasoline smell to it? anyone with this problem and solved it, please help me out

    should be on the fuel rail somewhere. i would at least do that and check codes before you start throwing money at it. check to see if you are getting good spark too.

    A bad map sensor will usually cause that kind of problem. I know I broke the vacuum line once, didnt know it, and the car ran like crap, dumping fuel. Just a thought though, check that stuff Josh mentioned first

    I replaced my fuel pressure regulator approx 2 months ago. The car had an extremely long crank time. Fixed that problem. The car cranks like half a crank and its turned over.

    My mechanic did it for me and charged me like $175 for parts and labour.

    well, guys, problem fixed, so i took the car to get a high flo cat not before, but just after the muffler, (sounds relly nice) when the car was in the air, i noticed a god damm sensor just there, unconnected, so there i was looking up like a dumbas searching for the connector, then i found it, it was alittle bit above the oil filter and the sensor fits in a connector on the engine block, can anyone tell me what that was by the way? its a lillte oval sensor with one wire and one male pin. I turned the car and noticed it turned right away, so i tought that the cat had done it good. When i was backing off to leave, i noiced something wasnt right, but it was good that it wasnt right u know cause the car responded like crazy, i put it in drive, and daammmm i coulndt believe it, for reals people, the car hauls ass now, the first thing i did was call my friend with a 97 16 sec. flat malibu, and raced him, i left the guy about 3/4 off the car behind, im so happy. MY friend has a cold air intake and some muffler, i have a short ram intake high flow cat and the racing dynomax muffler with dual exhaust. THanks alot everybody!
