Hey Guys-

Thanks for the tips. Among many other things I played with last night (removing the fuel pump relay, resoldering, cleaning contacts, removing and cleaning the fuel & ignition CU's, check wiring, vaccuum), I figured out how to use and read the fault codes. I found that I had three faults:

213 Throttle switch signal
122 Air temp sensor signal
214 Ignition RPM signal erratic

If it's useful to anyone, a complete explanation of all of the fault codes can be found for free at

Now all I have to do is figure out how to reset all the codes....I've been pulling my hair out trying to reset the damn thing. I know you have to view all the codes first, then reset the jumper to A2, hold for 5 seconds, wait for three seconds till red appears, hold it again for 5....blah, blah, blah, but it won't reset. What am I missing?

Thanks,
Steve
