This was an early post in the thread that was telling you of this common problem

So whatever is causing high idle hasn't been affected.
Surprising he 's not getting code for LO TPS V.
But a pointed out here this does not seem to be your issue.

Perhaps it is the PROM chip thing.

For those of us lucky to live close to Haibeck a simple drive to his shop and review would be the key to success.

You may want to email him and have him read this thread and work with you to solve your issues IMO.

He would know best what to try next and get you to an ultimate solution.

That is why he is the ZR-1 specialist. No one knows em like Haibeck does as many will attest too.

Now there are others who are also very good with the ZR-1's like SGC and DRM not to slight them at all. Or Jeff at PNW ZR-1.

But I like to support those who advertise here >> http://zr1netregistry.com/index.htm

or like Jeff who is on the forum here all the time with advise etc.

We support those who support us.

I hooked up the secondary map corectly and checked all the vacuum hoses, changed check valves. Now the secondary system works! and car pulls great, I think I still has a little vacuum leak but I think its from pcv valves, I will have those new in couple of days and we`ll see when I replace them.

aslo I changed pilot bearing because of tranny noise, luckly as me and Bill Boudreau / zfdoc.com (which send me a long email with some advice) thought the source of tranny noise was the pilot bearing. Now the zf6 doesnt produce any noise and is really quiet.

On the PCV valves.....I bought new top F shaped connector and new injector housing connectors back in 05. I installed them and they worked great for awhile. Now I just gave up and bought the expensive SAMCO replacement PCV top and bottom hose set from LIMEY.

I do believe if you use the car enough that the amount of oil blow by in our PCV system degrades the rubber PCV parts made from standard rubber in a fairly short time so that they start to leak slightly. As time goes by they degrade progressively and the small leaks become bigger & bigger & bigger.

This is JMHO. The only thing I know for sure is that the new rubber connectors were tight up to about a yr ago. They don't seem to last long.
