I was just wondering if my computer is bad. I have a check engine light but when I put in the jumper wire to check the light. All I get is one solid light. Am I doing it right. OR is the computer bad.
You have a 91, you don’t need a jumper. Read the Teg Tips.
What he said. We even have an ECU code chart.
your right but i have a 92 computer in my car so I still need to know what is up
Something you should have mentioned in the first place. :roll:
