Re: High Idle
What do you mean by "refinished the TB"? Were the plates removed? Any part of the throttle mechanism touched?

Re: High Idle
Right. That's what I thought. Probably send the TB to Marc H and have him reposition the throttle plates and do the spring mod for it. Then you need to do the Min Air adjustment.

Re: High Idle
Well pulled plenum again, disassembled and reassembled the TB. I have no idea what changed but the Z runs just fine now. WTH

Re: High Idle
You probably repositioned the throttle plates correctly.

Re: High Idle
Was the MAP sensor electrical plug connected when you pulled the plenum? Had the same issue with the 88. Plugged it back in and idle was normal.
