Hey everyone - ep3 replaced clutch and mounts recently- no issues. Problem is it sat for 3 weeks while I waited for spare time and parts.

Everything is back together now this is what happens.
Engine starts fine , then as soon as it begins to warm up the idle begins to fluctuate from 1.5k-2k rpm constantly. The car drives but it will stumble in revs if chugging around at lower speeds. It feels basically that it is running constantly in cold start.

I have taken off the icav cleaned it thoroughly , checked the gearbox ground etc , no sensors are off no ecu light on dash etc.

My question is what else could I have missed ? anything else I should look for ?

 

I would just re-check every bolt/sensor that you touched during the clutch install.

-Make sure you have no vacuum leaks
-Make sure you have all ground wires bolted to the frame.

 

It sounds like the engine is "relearning" its idle as if the motor had been swapped, since it hasn't ran in awhile and you likely had numerous parts removed/disconnected. Is your issue improving? (Is the fluctuation more rapid and between a narrower range of rpm's?) That's the exact thing my cars have done after swaps and slowly resolve over a few days. After my a2 swap Acura tried to force the relearn but I ended up having to wait it out. 4 days later with daily driving each day, it was gone.
