My module says the electronic spark timing circuit (bypass) is bad. I am striking out finding one for a 1991 Buick Park Ave w 3.8 L eng. It looks fairly easy to fix but I need the part. Suggestions? Thanks in advance for understanding an old mans questions!
I found the part but it wasn't the problem. After much drama I found a mechanic who located the problem. The ignition module and the coil were bad. The unit was replaced and the car is running great again!
