I got the truck back from the shop and all was fixed. However the first few start up the truck roared badly when cranked and shook a bit. A bit if idling and it calmed down. After a few starts and drives the roar and shaking went away. I suspect it was the ecm relearning. The base idle seems to have leveled at about 750 rpm or so.
Only remaining issue was a chirping. Sounds like a cricket when idling. When driving it goes away. If you throttle the truck up to about 1250 rpm and the chirp goes away.
Took it to the shop and he wants to have it back to tweak. He wants to locate the chirp. Not sure if it's a belt squeak? However he said he feels the idle is too low? Truck runs fine and does not try to stall even with Ac and a hard brake with lights on. So I figured it was fine. Maybe he thinks the timing is off? Truck never has power but we have gotten used to the civic again so it feels even slower at acceleration.
So what should base idle be? I don't want him faring around with the idle if it's ok.

Refer to PROPER IDLE RESET. DO NOT let him touch the idle adjustment screw. There is a reset procedure for these Cars. You will hear me and Ed always talking about Mitsubishi dealerships. That's why we take them there. These Montero sports take some TCL but they are well worth it. ;D

700 +-100. Just need to find a good mechanic. Preferably one that is mitsu certified or at least familiar with them. Only thing I have the dealer do is tranny flushes and timing belts and more than likely the TPS in due time.

Almost guarantee it's a belt. I had my belts changed out and the power steering belt was chirping terribly. Bought an OEM belt and immediately cleared the chirp. Huge difference. OEM belt has a felt-like surface, the replacement belt did not.

Thanks to you all. Glad I trusted my instincts and asked. I felt the idle was spot on. Truck behaves same as it always has. I will tell him to leave it be when I take it back for the chirp. Funny dclambertt that is the very belt I was eyeing...  |

Its like 700 RPM for the M/T and 600/650 RPM in drive for the A/T. redraif, BD's correct. Do not EVER mess with the idle or let anyone else mess with it either. The 'idle' is set - and I use that word loosely - by adjusting a caped screw in the TB. Setting this required a MUT, BTW. After that, the ECM/PCM takes over. No matter WHAT you adjust that screw to, the ECM/PCM will 'adjust' things so that idle is 600-700 RPM. There is no such thing as changing the idle on the Montero or Montero Sport, Eclipse, GT, EVO, etc. That said ... the techs DID have to readjust this on m big Sport when we did the 3.5L conversion. But, that was primarily due to the swap of the 3.0L TB onto the 3.5L intake. Having to do anything with the 'idle screw' in the TB is a very, very rare thing. Edward |

Excellent. Seems my idle is sitting right where it should. Good to know. I know fiddling with the set screw on the bird opened up a host of issues and I made sure to NEVER fuss with it. I will make doubly sure he does not touch the sports. Thank you All for the info!  |
