I have a 97 gs was working fine this morning but out of nowhere the idle sounded like an 1960's car. I also lost some power and if i dont keep the rpm's in 2 some times the car shuts off. Also after 4rpm the car sounds ok but some power are missing. I already change the spark pugs and wire. Fuel looks fine. Please help if u can. Thanx

 

did you check the timing?
