It just keeps getting better and better. OVP relay is fine. Ran some sea foam and still nothing.
So, I pulled out the rear seat to fix another issue, and noticed the connector that comes from the harness to the fuel pump was corroded and literally fell apart in my hand. So I fixed that issue, the car started to run fine again. I took it for a drive up my street, and then it started acting up again. this time even worse. total lack of power. I had a hard time even pulling it in my driveway. I kept flooring it, and it went nowhere. It has a very hard time now even revving up and when it does, it now backfires into the intake.
What is going on with this car? I have checked and or replaced every sensor except the throttle body sensor. Where is the port I connect onto to check fuel pressure at the distributor? BTW, yes, I replaced the fuel distributor with a known good working one already and I replaced the entire ignition system including the control unit mounted on the front wheel well with a known good one. I've narrowed it down to three things 1). faulty throttle body sensor 2). clogged fuel tank screen 3). dirty injectors.

Anyone have any problems like this? Where do I go from here? Do I just give up and tow it to the dealer , who is about 40 miles away? or keep at it? I've just about given up on this car.
