Ok. I had been posting on the facebook group about this but I know that is really not the place so I will continue here. Here is what was wrong and what I did. It is a 1995 Mustang GT with a 1998 Explorer motor in it. X-pipe, CAI, cam and head work. It has the GT40 heads and intake. It is also running Moates QH and Binary Editor. So it had been running super rough when cold, backfiring and bogging down, then this started to happen when it was warm as well. Previous owner cut and spliced the engine wiring harness at the block at the firewall, the TPS and the O2 sensor pigtail. Car had the ICM and air temp sensors disconnected. Connected the ICM and then started getting a nasty moan from it at idle, thought maybe the TPS so I tested it with a voltmeter and it checked out. Thought maybe wiring issues with the sensors so I found a nice harness on eBay and bought it then installed. Car then would not start, discovered that I had forgotten to tighten down the CAI and still no start. Pulled the ECU and noticed that I had bumped the QH loose from the ECU. Reset it and nothing, removed it and it would start but not idle. Felt like I was getting somewhere, turned in the screw on the throttle body so I could trouble shoot and figure out what was up with it running. Tried reconnecting the QH and no change, it would run just like before and QH would not pull any data while running to the dashboard in BE. Someone suggested timing, I thought that couldn't be it, I didn't touch the dizzy. Went ahead and attached a timing light and the number 1 was firing randomly not in any sort of pattern, huge misfire issues. Also, I could notice the sound of what was the injectors that I had never heard before. Car is smoking from exhaust, never did that before either. Another post to the FB group and it was suggested the PIP might be bad. Ordered a new dizzy from AM and installed it. Found the timing marks and started car. Was able to set it at 10 degrees and then remembered that I need to pull the spout, pulled it and car died right away, put it back in and car started right up. Running rough and smoking, still hear the injector noise as well. I am at a loss with this. I am now thinking that either i fried the ECU or I have a bad harness. Any suggestions on the next step?
