Since I installed my MEVI and then reinstalled my USIM ive had some problems with the car wanting to stall on start-up. I figured it was due to playing with the IACV so when I got the idle correct I just didnt really worry about it: I still have to tap the gas on start-up to keep the RPMs from falling back down to 0 after ignition but after that it sits fine at about 700. Recently however the car keeps wanting to stall while im driving for the first several minutes anytime I put the clutch in to come to a stop and, again, I have to save it from stalling by tapping the gas. Ive done no work on the engine lately.. is it possible that I just need to play with the IACV some more. Oh, and I do have a PF TB if that makes any difference. Thanks guys,

pulling any codes? I am guessing it may be the MAF sensor ... but dunno. Any vacume leaks that you can find?

 

How were the condition of all the gaskets during the swap?

 

The gaskets seemed fine during both swaps (only about a month or so period between going back to USIM). I guess I could just keep looking over each of the vacuum lines to check. Since you mentioned the MAF I will say that when I hold the pedal at about 2000 upon start up for a few seconds to prevent stalling the engine sounds very awkward.... almost exactly like the time I forgot to plug in my MAF a few months ago after cleaning the TB.
