hard bucking and backfire then it dies - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

so to start off i just got a new wiring harness installed at a shop. they put in a s13sr harness in to my s14 with a redtop sr20det for my power fc. the next day i got the car tuned. i drove the car home that night it drove great no problems. so im driving home from school and i turn a corner all of a suden the rpm just drop all the way down to 0 and then the car bounces back agin so i keep driving. then it starts to buck and then backfires along with droping rpm. i also herd this weird electric sound when i pulled the car over that sounded like the was some thing frying behind my gauge cluster. but i could only get the car to drive a few feet before it would buck and backfire and die.
