Hi everyone. Working on my son's '94 SC... again. His car has a 5-speed and a Moates tuner. He's has an EGR/vacuum leak that needs to be dealt with. Already have the bock-off plate and cap and will install it.
To me, the biggest problem is that I can't read the codes with either of my two EEC IV hand-held scanners. Both have new batteries and I do get signals to the scanners but they are incoherent. I don't get the engine identifier beeps or anything in the normal fashion (how it should according to the manual). This is a newer problem. It scanned before but somehow lost this ability a couple of months ago, according to my son. A month after that the car died in my driveway. Besides the EGR problem, there were some other things: PCV valve "fell" out of the valve cover and PCV vacuum lines were incorrectly hooked up. This has already been corrected.
My son said that although the code scanner method wasn't working, he was still able to datalog with his laptop.
First thing I am having him do is pull & reinstall the EEC to make sure the connector and wiring is fine.
Have any of you run into this code scanning issue?
Thanks,
-Allan
