code 21

Post by **jdmDAvey** » Sat Sep 03, 2005 7:43 pm

After she warms up, itll idle fine and the a/f ratio is good, but then the a/f drops to rich and she tries dying. Also, right after I start it and its not quite warmed up, I can rev it up fine. But after it warms up ill rev it up to like 2500- 3500 and itll start misfiring and sputtering shaking the whole car. It threw code 21 which says that its missing signal in primary coil. So, do you think I should replace the ignitor chip, or do you think that my coil packs are bad. Anyone had the same problem? Thanks

Sounds like a bad ignitor, it is always good to have a spare ignitor and a spare coil.
