Subject: Re: '94 LT1 dies out... by screamin_conure on 2011/9/10 16:58:42 Well, back to the drawing board. Stopped by the car owner's house yesterday after work. I did the paperclip trick and got a "C12" for module 1, meaning no codes. Module 4 had an H44, and module 9 had an H71 if memory serves correct. I don't think either of those historical codes pertain to the issue. I also did injector resistance readings. Results as follows (cylinder number -resistance reading): COLD = 1 -13.6, 2 -14.2, 3 -13.6, 4 -14.3, 5 -13.6, 6 -14.5, 7 -13.6, 8 -15.0 HOT = 1 -13.2, 2 -13.7, 3 -13.0, 4 -13.2, 5 -12.9, 6 -13.1, 7 -12.9, 8 -13.1 The car sat and idled for about 30 minutes, with a few blips of the throttle thrown in, to get the injectors hot. However, after 30 minutes it died out on its own, and we couldn't get it restarted (just cranked and cranked, but never fired). So, we just went ahead and took the hot readings. I noticed a couple of times when we blipped the throttle that the engine stumbled a bit when it was coming back down to idle. I also thought it was kind of strange that the resistance readings went DOWN or stayed the same on the hot injectors. I thought they would have gone up. He's still running the original Multecs. Even though they're old, I have serious doubts that the problem is injector related. Anyway, the car's owner is taking it in to his mechanic Monday afternoon (assuming that it starts again for him). I really thought we had it with the new coil wire. I felt bad that I couldn't help get it sorted out. |
