Hello, here my problem,
2003 Vibe AWD 1.8L 193,000 Miles.
First had a 02 sensor Lean code check engine light at apx 180,000 miles
Then at apx 182,000 miles engine lost power and needed Coil for cylinder 1 replaced. IT was replaced and all plugs were replaced. Ran fine.
At apx, 190,000 miles a misfire began when traveling up hills or when above 4,000 rpm during acceleration. When this happens the check engine light flashes until the engien is no longer under load. Code showed to be a misfire on Cylinder 1. The dealership checked the newly replaced coil and moved it to another cylinder and said that it was still missing in cylinder 1. They said it could be a burned valve or an injector but would need to do a compression test and an expensive diagnosis.
I am wondering if this could be a intake manifold gasket. The car is drivable but a I barley make it up steep hills and can not accelerate above 4,000 rpm.
Please advise on the what the problem may be!
Thank you!
Steve,
