I have an issue with my 91 SE that has me scratching my head a little. So last wednesday I drove my car to work no problems ran great, I came back out a half hr later and it was misfiring, I let it sit for a few hours and tried again and it still was missing. I started doing some basic diagnostics with spark, and it seemed that my spark was weak on cyl 2 and 3 as compared to 1 and 4. I could pull off the boot for either cyl 1 and 4 and the car would just about stall, with cyl 2 it did nothing when I pulled off the boot and when 3 was pulled it actually ran better. I tried swapping out the coil pack for cyl 2 and 3 and it made no difference, I also put in a ignition module and had no change. the car sat from Thu-Tue, I started it up to do some more poking around and when I started it it ran fine for 2 minutes then started misfiring again. I hooked up a noid light the injector plugs and found that cyl 2 was not pulsing at all......unless you disconnected the number 3 injector plug and then 2 would start pulsing. I tried to see if cyl 3 did the same thing but it always pulsed no matter if 2 was connected or not. I ohm'd out the injectors themselves and they had from 2-2.8 ohms each (with engine warm). Im thinking that this is an ecm issue due to the sporadic nature of the problem and wiggling wires didn't change anything. Anyone run it to this or have some thoughts on some more checks?? I plan on hooking up freescan in the next couple days to see what I can see on there and also following the flow chart for the injector issues in the manual, but I figured id ask first before just in the slight chance that someone may have run in to this.
