My '88 has in just the last couple of days given me an unexpected worrisome
surprise. I guess I'll keep reading the recent thread - but does this sound
familiar to anyone?
I have noticed my idle speed wavering between 1k & 2k, but it's just annoying
- I really didn't think it was a problem... but, just yesterday, while
driving on the highway about 50mph, I noticed a brief power loss. - not
enough to stall me -  I just kept driving, and it went away, and ran fine for
about 3 hours after that. Today, sort of the same thing. It just lasts for 5
seconds or so, and there seems to be no way of predicting when it might
happen. I have a spare ECU, and thought I'd plug it in and see what happens.
Will a Digitool save the day, and make it fairly obvious what's happening, or
am I going to have to take it to a pro?
