Car sputtering, backfire, and won't rev high
Car stalled and wouldn't start awhile back. Had it
diagnosed and replaced the maf sensor and crank
shaft sensor. After the crank shaft sensor was
replaced it started. It runs badly and sputters and
backfires when reved. It has barely any power and
once it hits about 3k rpm it looses all power and
sputters and backfires. Help....
