1984 245 Ti, pretty sure it was intercooled at dealership after purchase.

I live in Wisconsin, so this thing has been a pain to start so far this winter. I've had it for 2 months already. Temperature now is like 30 fahrenheit in the mornings.

The car will fire right up, but then die. It will do this numerous times, so I usually give it a little gas when starting. It will run then, but I have to hold the gas and sometimes even pump it because the idle will still fluctuate even if I hold the pedal in the same position. After its started, I give it gas for about 20 seconds, then let off. It will idle by itself at around 1000 rpms, as shown by tach in cluster. If I give it gas again, it will sputter first then slowly rev back up, so driving away is tricky.

It will idle fine but runs like crap until it is warmed up a little bit. Once its warmed up, it runs great.

After reading the Bentley it seems the start injector only sprays fuel for a few seconds while the engine is cranking, so I assume that this is working because it always fires right up.

Since it dies immediately, it seems there is a fault with the Control Pressure Regulator which should richen the mixture until it is warmed up, when it is then cut out by a thermal switch, correct??

If I'm on the right track here, I know there are fuel lines, electrical wires, and vacuum lines running to this little unit which is behind the distributor. How should I begin to diagnose why this CPR isn't workign right??


Thanks Guys, this one is a little trickier, I appreciate the help,

Smith :-)
