Re: lean missing and ECT sensors

I have idle miss problem in my 87 TC 5-speed also.  I also have a detonation
problem just as the boost starts to come up (before the knock sensor can stop
it I guess).  Any other suggestions would be appreciated.

 Yes...it lean misses ;) It doesn't do it when in open loop (startup) or
 off-idle...just when warm and idling. It's probably just the computer
 (normal). >>
