Cold start problems
 
Where should I start looking to find cold start issues? The car starts fine, but idles very low, and when given gas, will bog down. Once warmed up after about 2 minutes of driving it is fine.

Warm up regulator and the temp sensors at the front.

Thanks, I figured it would be a simple answer. Now, how do I find these and are they repairable, or do they have to be replaced?

Before you go throwing parts at it, you need to establish a base line, by making sure your CO and timing are set properly, and a fuel pressure test. If you plan to work on your car yourself, invest in a proper CIS fuel test rig, and a CIS troubleshooting guide.

Good posts! Don't start "throwing darts" to find the problem.
As mentioned, you need a fuel pressure gauge to measure the
cold and hot fuel dist. control pressure from the WUR.

Also, you need to determine if you have 12V going to the
WUR and aux. air valve. The 12v comes basically from the
same circuit as the fuel pump voltage and affects how
the engine runs as it warms up.

Check out this website (Systemsc.com). It may provide some
helpful info.
