I've got a 87 tpi and I can't seem to figure out why it's acting this way.
The idle is jumpy, it goes from 1000 rpm to 500 at will. Sometimes when coming to a stop it'll be around 2000. I changed the ICM, and it's better but still all over... and to top it off it smells really gassy. I searched, but I didn't find much, has anyone got any suggestions?

 

openning suggestion would be to check your fuel pressure and post back on the board.

 

CTS sensor can do this . Also the surgeing part could be a fauly MAF burnoff relay .

 

I hadn't thought of that, my temp light does come on when I start the car I thought the meter was dead... Where migh the CTS be? My haynes manual isn't great.

 

on the front of the intake manifold...under the throttle body and such...

 

While I'm at it, I can't seem to get any codes except 12 even though my car is running rough. That seems odd, but I'm off to check the sensor.

 

Well, I disconected the battery and the check engine light finally came on. I got my code reader out and got a 15. Temp sensor it is.
Thanks for the tips guys!

 

cts = coolant temperature sensor?

 

yeah, but I'm stll having other problems, I'm changing the Fuel pump and I noticed the fuel pump relay wiring looks like five year olds patched in up. oh boy.
