Ok, this is my last effort of trying to get my car running, here is my giving up pic thread...
http://www.contour.org/ceg-vb/showthread.php?69138-I-m-giving-up.
The main problem is the car is dropping spark from 24 to 1 degree, seems to be happening only around 2k and 3k rpm but also runs pretty rough under 5k rpm. Also after running the car and driving around a little it will die after you give it some gas everytime.
The original wiring harness was giving me problems with the front o2 sensor not having power because several of the clips were not latching together, got that problem solved with the stock 3L uim on and the car was running great. Since my wiring harness was pretty messed up I decided to pick up a used one that appeared to be in good shape with all working connectors and installed my ST220 uim at the same time. Now with the ST220 uim and new wiring harness I am having the dropping spark problem. So here is what I have nailed it down to...
1. UIM couldn't cause a spark issue
2. Swapped out the coil pack and plug wires with some that I know for sure work just fine
3. If cam or crank sensor were bad the car wouldnt start at all
4. I believe the wiring harness is fine, but I did have to do some modifications to it which I believe should be working just fine.
To make a long story short the current wiring harness on the car is an 01-02 mtx cougar harness(which is correct for my car), however I did have to remove the crank and cam sensor wiring from an 01-02 atx cougar harness to install on the current mtx harness, I did that by using a very small flathead screwdriver and pushing the wiring pins out of the connectors, and pushing them by hand back into the their appropriate places. After I did this wiring change I am also throwing a fuel rail pressure code now, which I haven't looked too much into, besides making sure the fuel sensor is plugged in and doesn't have any leaks anywhere.
Before I switched out the cam and crank wiring I had the 01-02 mtx harness with just the two crank sensor wires soldered together and had the same issues. Didnt have the fuel rail pressure code with this setup tho.
So who thinks I should spend even MORE money on this car and send the better part of my 3 wiring harnesses to svttour along with $100 and hope that fixes my problems. OR should I replace the cam and crank sensor with some new autozone sensors at the cost of $50 even though those were never changed or messed with?
Thanks in advance to anyone who can help me, because otherwise the car and all its mods are going to be forgot about and put into storage for about 2 years.
