the other day I left on a trip I checked everything and it was ok. along the way during my trip. when I slowed down to take a turn onto a junction towards my destination the car all of a sudden started to rev up and there was no acceleration in speed but the gas started to go down really fast.. I made it to the town with only 1/4 of a tank left in the car. and I made this trip many times before. so it shouldn't have used 3/4 of a tank in that little mount of time/ miles. but now every time I start the engine. it runs rough and you can smell gas... any questions what this is?
what does it mean. when my car idle is rough and you can smell gas? on 2003 Pontiac Bonneville
Most likely a defective fuel pressure regulator.....see youtube for a how to test video!!... Enter your info in search bar... Seeing it being done is a heck of a lot better than reading about it being done!!! ...Plus i am a poor typist...cant speel to good nither!
