Hi, My car will fine for a few miles then it starts hesitating and jerking and when I press the gas pedal more the engine light goes off and it drives normal. It has also been stalling when I come to a stop sometimes.
Ok, first thing I need too ask is..Whats the make model and year of your car?
1994 Q45 Infiniti
2003 Pontiac Grand Prix
ok, on the 94 Q45 you may need too check the connections to your MAF sensor as that seems to be a big problem with that car, have you had a diagnostic hooked up yet?

SOURCE: it feels like gas isn't
Have the fuel pressure checked- this would determine if your fuel pump is working properly. Its really easy if you have a gauge. you might be able to rent one at a part store. or it could need a new fuel filter
SOURCE: Car stumbles,hesitates,loses power on Hwy, randomly
Did you check earth connection of electric system?
SOURCE: car starts fine, but stalls at stops and takeoffs occasionlly
Most likely it is running too ritch. should be around 7%. Mine did ecactly the same thing and I had several things done . Had the throttle body cleaned and installed a O2 senser.runs great now.
Hope this helps
SOURCE: engine light is on ,code P0171, hesitates when start driving
you will need a code reader to turn light off
SOURCE: I have a 1999 cadi deville, the abs and traction
A few things could be wrong....it could be your brake control module, anti-lock brake system or a wheel speed sensor. The best thing to do is to get it into a garage and have them take a look at it and give you an idea of what is wrong. Either way, if you do not have the proper tools, you are better off taking it to the shop.
I hope this helps.
