Hey guys, I really appreciate this discussion because my 89 s10 4.3 started this same bad attitude stuff this week. At first I thought I just had a clogged fuel filter, but that did not fix it. So yesterday I found this discussion and one of the entries talked about a bad ignition control module and that seemed to fit my scenario. I changed my ICM last night and walah, my truck did not quit on me coming to work this morning. It quit about five times yesterday morning. I'm still a little leary but hopeful that it is fixed. On the funny side, all my coworkers laughed at me for bragging when they saw my truck sitting in the parking lot with a flat tire. Holy crap!
