List,
 
If anyone can chime in on my "issue", please do so directly to me  
off-line.....I don't want to clutter the email site with non-TR chatter!   I'm 
hoping 
that someone out there has had a similar problem with their 14 year  old truck! 
 
The vehicle is a 1994 Chevy S-10 Pickup 4.3L TBI V6 5 speed manual  trans.  
After it starts (from hot), it idles around 2500 rpm then settles  gradually to 
1100rpm.  Sometimes it'll even hang around 2000 to 2500  rpm between shifts.  
Normal idle speed is 800 rpm.  I don't have any  trouble codes from the PCM 
which I guess indicates that my problem is not severe  enough to send a 
out-of-range signal to the PCM (I hate when that  happens!).  All of the vacuum 
lines 
seem okay - at least all of the lines  that I can see to check or temporarily 
plug.  The service manual  diagnostics seem to be pointing me to the TPS or 
IAC so I'll probably rig up  some test leads and check those do-dads 
next.......if anyone has any first-hand  experience they can share, I'm all 
ears:)
 
No stinkin' PCM's, ECM's, TPS's, ABC's, etc on the TR6......
 
Thanks,
