I have a 1990 Pontiac Grand Am, with the 2.5 4 Tech. 85k Miles, and for about. 3 months now, after a trip. When ever I accelerate anything past idling RPM, wich is also abnormally high. I get a very loud popping sound, wich I can almost discribe as a very loud cork being popped out of a wine bottle, coming from the engine bay on the passenger side. And it will do it repeatedly untill I let off the gas, The car has never died while driving or idling just runs rough at a stop light or when parked idling, But in the mornings or when ever the car has sat for more than 12 hours, it is very hard to start up, if at all. I usualy have to wait a few hours to try and start it, and usualy starts up like nothing happened. Leading me to belive it gets flooded, wich goes with the high idling, the gas might just be seeping into the cylinders slowly as it sits. Anyway back to the popping, When driving like I said if I give it anything over just touching the gas pedal, it pops repeatedly and slows down. Any help with this will be greatly apreaciated. Thank you
have the same problem?
