Ok ...
Champion Plugs put in a few days before the stuff below.
Rotor and Dist. Cap on not too much of a problem.
Valve covers. Done ... not too much of a problem. No leaks that I can see right now.
Egr valve and transducer. ...no problems other then terrible design / placement.

I also used the plenum from the wreck. I checked autozone to see if the sensors where the same for the 96 and 97 model year. All but the Air intake temp sensor were the same. I used that 96 sensor on the 97 plenum. I also used the throttle body from the wreck and its IAC motor and TPS.

Car .. well the car is doing the same thing ... I needed to all of this anyway, but my work did not correct the issue.

The car runs ok for about five minutes.
Gradually, hesitation increases. As it increases idle becomes irradic.
Eventually (probably after 7 or 10 minutes), when stopping at a light or stop sign, intermittently rpms will drop very low, the Oil light comes as the car stalls or it comes back up to about 7 or 8 thousand rpms. If it stalls, it hard starting it again, but it does go over after a few tries. If it doesnt stall, and I step on the gas to pull away, I get a "dead spot" ... hit gas but goining no where. spitting sputtering ...

The check engine light is NOT illuminated .... going to put a OBD II on it now see if that'll tell me anything.

All of this started when I had a mechanic do wires and plugs.

Anyone have anything like this cooking ?


I posted this on a few boards ... let ya know if I find anything.

 

sounds like a possible CPS trouble ...

 

Hummm ... wiff no MIL / OBD code ?

 

It's a magnetic/hall device and in warm weather it seems to get old/weak over time and does weird things and won't fault code ...

 

I would replace your idle air control valve
