Hello, my name is Bobby. Thank you for the question. Can you tell me how the vehicle is running besides the check engine light being on.
Customer: replied 2 years ago.
It running good, I found out that my compression was low in the 4 cyclinder. It was was at 120 and the rest where at 170 to 180. Put some Engine restorer in it and it seem to to running better now. But sometimes the check engine light come with same code but it not a hard code, it pending code

Eventually you will need to pull the cylinder head and have it rebuilt if you want to fix it. This is a common issue on this engine and typically stems from failing valve seats. If it is running okay I would not worry too much about it right now. Let me know if you need more help.
