Good luck Jeremy. Let us know how it turns out.

It's been a few days now (five to be exact). Inquiring minds want to know, did you find out what the problem is yet?

Not 100% yet - we had a problem duplicating (as in it idled steady as a rock at the shop) although my mechanic at this point "thinks" its the Idle control valve slowly failing. He checked mixture and idle setting - and they were fine.

He explained to me that since the ICV takes over around 1100 rpms - and when the idle microswitch is engaged, that with 993ss cams That the ICV has got to be functioning 100%.

SO, once I get my new ICV I'll let you know
