Closest junkyard that has those Caddies is about 30 minutes away. I had to order the TPS and ISC connector from Carquest since they can have it in the store by 2:30pm. I had to have the parts today so I can get to work tomorrow. Plus all my other cars have problems so I can drive them. (locked up motor on one, bad tranny on another, and the last one is down to bare metal and body filler.)

If there was a junkyard within 2 or 3 miles, I would have walked there and bought the parts. It would have been about 1/10 of what I've wasted so far.

Also when I plug that ISC connector off, it just broke into pieces. Even those metal clips fell off the wires.

I wish you good luck on getting some rides fixed.

I just bought a rebuilt tranny and stand alone computer for my truck. My Bonneville just needs a little more body work, new windshield, paint, the bleed the injector lines, register, and then drive.

I put a new TPS, ISC, and replaced all the vacuum lines. It'* still has the code 32, stumbles, runs rich, and sounds like a misfire.

I get a little bit of vacuum on the EGR solenoid while at idle. If I push in on the EGR, the idle gets rougher and almost stalls. Runs the same with or without the EGR valve or EGR solenoid hooked up. One O2 sensor says 900 mVolts and the other is 800 mVolts. Both are saying Rich. TPS is set to .45 volts. ISC clicks when you first turn on and clicks for 20 seconds after the engine has been turned off. Last thing, I think might be wrong is the MAP voltage is only .1 volts.

I just drove the car and it still is running rich and stumbling around 1100 to 1400 rpm. The computer says I'm getting 4.3 mpg. I use to get 22.6 mpg before this started happening.

I tried checking the wires coming from the MAP sensor to the ECM. The light green wire had resistance, so it was good. The other two wires gray and black/pink, I couldn't test them. The gray wire goes to the MAP, TPS, and ECM. TPS is working fine. Then the black/pink goes to the MAP, MAT, and ECM. MAT is working. I even went back to Autozone and said the MAP was faulty and got another new MAP sensor, but still doing the same. I also replace all the rubber pieces and rubber vacuum hoses. None of those are leaking.

I watch a video on Youtube about how to test your MAP sensor. It said the MAP sensor should be at 5 volts at idle and for every 1000 RPM is should drop 1 volt. My MAP sensor is at .1 volt so that'* probably why it'* rich because it thinks it'* at WOT.

One problem is which wire do I check for voltage on the MAP sensor and why is the TPS and MAT working ok, but each share a wire with the MAP sensoer? I'm thinking the gray wire is bad since my TPS did explode.

Here'* a wiring diagram for my car I found on Autozone'* website.
