I finally got the '94 940 running. A new fuel pump, distributor, distro rotor and spark plug wires to get it running. The only problem I still have is when the AC is on and I idle, the car shakes and runs rough. I know it is getting fuel now. I don't know what to do to try and fix it. Anyone else ever have this kind of trouble before?

Edit: Finally broke down and took it to a shop. They finally found that a hose going to the intake was crimped. They replaced it and now it runs smooth and has much better power off the line. I just wanted anyone else that has a similar problem to know how it was fixed.

 

Have you cleaned the throttle body yet? Since the pcv feeds into the TB it gets really nasty to the point the throttle blade will not close completely. If it doesn't close completely, the TPS will not know it's idling and the ecu will not activate the idle air control. The TB really needs to be off he car to do a first class cleaning. The vacuum nipples are often completely closed off with crud. I've actually had to use a tiny drill bit to clean a few. And...if the compressor is a little harder than normal to turn combined w/ a dirty TB and/or misadjusted TPS...bad idle...

 

Are there any online instructions on how to do that? I have done it for my V40 but not the 940.
