Ran fine one day...would not run the next...replaced Idle Control Motor and cleaned throttle body...udles very slow and rough..seems fine at higher speeds...suggestions?

Welcome to the forum!

Moved to correct area.

Start with testing your fuel pressure.

Thanks. should be 41 to 47 psi, right?

Ya, right around the 45psi range. That'* with key on, engine off, KOEO. Then start the engine. may go down a little bit, but still in that area. If it'* low, you either have a clogged filter, or a weak fuel pump.

Wondering if a low idle/stall could be the Fuel Pressure Regulator?

yep, you can take the vacuum tube off and smell for fuel, if you can smell it its bad. what pressure readings did you get?

Finally got a engine check reading...P0300 Random Cylinder Missfire, P0171 Bank1 System to lean, and a P0102 Mass Vol Air flow Circuit low input. Fuel pressure looks good...

i would start by cleaning the maf,

Cleanned the MAF...still won't idle...thinking there is a vaccuum leak maybe...but can't fnd one...
