I have a 73, 1.7 liter with everything new or checks out OK on the Fuel Injection. One culprit left the CPU. I'm in El Cajon Area of San Diego. Any rebuilders, besides sending to PelicanParts?

Are you sure? Those are pretty much bullet proof in general. I'm in Temecula and will loan you one to confirm. It's off a 2.0 but should work to confirm or negate your supposition. If your not very well versed in 914's you might want to post up what problems your running into.

Thank you for your recommendo.
Yes I consult the site. Really first class and informative. I post because I have exhausted everything else that could be bad except the vacuum pressure sensor.
I might take you up on your offer. Because the local recycling place (Autobahn, in El Cajon) Let me hook up 2 CPUs that they have that are used. They cautioned me however about the similarity in malfuncton of CPUs. They sold one, which was defective and had to send a customer 3 more! Only one was good. Anyway I hooked up the 2 CPUs and same dproblem with the idle as mine. Advance the throttle and problem goes away.
Thankx
