Ok so after I drive my 92 civic si hatch for long periods of time my engine light will come on. And It seems to not have alot of pick up and sounds alot louder.If I let it sit for a bit it will be back to normal.Anyone have any idea what the problem is, or how to find out the problem. I did a search and found nothing but awhile ago I read something similar to this and I think it was some loose wire. But that seems wierd about my vtec..... could it be the solenoid? Your help will be greatly apreciated
