I got a code 42, a code I have never gotten before. This happened this morning. It's cold and damp outside. The Fiero started a little rough and ran rough while the SES light was on, but never felt like it was going to stall. I let it warm up like this for about 5 minutes and then switched the car off and restarted it, which then it ran perfectly and Idled perfectly (well as perfectly as a 20yr old car will idle). This code 42 is for electronic spark control. I have a new coil, module, plugs, cap roter. The area I'm really looking at is perhaps a pick up coil. The connectors seem awful btittle and it's probable the same pick up coil from 1984.
Has anybody else had experience with this code? I've replaced a pick up coil on my GT, but the distributor is harder to get at on my coup and I've been putting off pulling it.
Thanx,
Rick
