Should I replace my ICM? '89 Bonneville
Delta 88 Royale Brougham
engine 3800 Vin C, Mileage 202K
1989 Delta 88 green goo when I went to change coil pack with an AC delco d552 coil pack
Problem cold Hard start when ambient temp is less 30 degrees
Coil ohms readings; secondary 11.8k; 12k; 13.84k; primary .7ohms; .7ohms, 0 ohms
Car runs fine otherwise.
Any suggestion on what use to clean the green goo up. It is mostly on the lower third of the module. If I can clean it up I think I might try it as is. I was not planning on needing an ICM as well but may have no choice.
Also any suggestions on ACdelco ICM vs aftermarket. On this page aftermarket has had some problems. Normally I go ACdelco; this ICM module (ACdelco D1922A) is very expensive.
Thanks for any suggestions.
