Ok let me preface this with I have spent hours reading searching and reading through the other posts but haven't found a fix yet.

Background: This is a 22re from an '87 that was rebuilt and dropped in my '85 about 20k ago. Has worked great since then.

Orig Problem: I first noticed it as a hesitation on acceleration and then when I let it idle (disengaged the clutch) the rpms would drop real low...400-500 and it would stumble until I opened the throttle and brought the rpms back up.

What I've Troubleshooted:
-TPS adjust and replace (checks fine)
-AFM checks fine
-cleaned throttle body
-cleaned IACV
-replaced plugs (wires are fairly new)
-checked distributor
-no vacuum leaks
-no EGR problems (blocked off)
-burped the coolant
-Injectors professionally cleaned 10k ago
-O2 sensor replaced
-pcv replaced
-


Problem Now: Initial start of the day is real smooth, idles fine about 900-1000. Idle drops to where i have it set about 750-800. then after about 2-3minutes it starts bogging down and stumbling. opening the throttle raises the rpm and smooths it out. Disconnecting the TPS will raise the rpm and smooth it out after a little bit. After about 6-10 min of a riased rpm it all smoothes out and runs fine. then for the rest of the day it works fine.

This is my daily driver and i need it to be a little more reliable than that. Any thoughts? Thanks

...and replaced almost all the same stuff. I read in another thread here that it may be a bad fuel pump. I am going to replace that next week.
