I own a 90 N/A and just last night found the "Check Engine" light on. I was thoroughly bummed out. Recently bought it used from a Dealer with no warranty has 113K miles. My question is what would cause the light to go on? Is it expensive to repair? Should I do it myself or take it to a Z specialist. If so does anybody know where in Southern Calif, L.A. area I can take it to. Please help anybody.

Thanks in advance.

Well you need to go to twinturbo.net and to either the tech section or faq section and find the article on ecu diagnoses. You can do it yourself. Goodluck.
