DRIVE BELT CRACKED.
REMOVED AND REPLACED DRIVE BELT, VERIFIED THAT DRIVE BELT IS SEATED ON ALL PULLEYS CORRECTLY.
serpentine belt needed replacing
Check engine light was on they said it was due to the knock sensor needing to be reprogrammed and the "evap vent solenoid" needed to be replaced. I have not noticed any change in mileage or performance so I decided to not pay the $300+ they quoted me ...
Car wouldnt start one morning. Took off the coils and removed the boots and saw that cylinders 2 and 3 werent firing. Replaced the coil packs and the ignition control module and its been riding smooth since.
Rocker disintegrated, shoved intake valve open, crashed into piston, rod fell apart, bent oil pickup in oil pan. Replaced rocker and entire bottom end.
Spun a rod in the rebuilt motor after 4k miles. car is down and wont be repaired again, not worth putting any more money into. gonna sell it to pick n pull
