Looking for help with 2003 camry 6 cylinder with erratic idle. Replaced starter then it started having erratic idle immediatly after. Did not do this before working on starter. Double checked all connections. Started getting P0102 code. Went ahead and replaced MAF sensor.

Idle will jump to about 2500 rpm then fall to 2000 then right back to 2500. Cycles about every 3 seconds.

 

Did you disconnect the battery to replace the starter? If so this can cause idle issues as the computer relearns.

Did replacing the MAF solve any engine light issues?

 

I think, the main point is the battery... there are some problem with the battery that causes it to idle.

 

Full house, you are right. But how do you reset the computer? Anyone. I just posted a 2002 v6, disconnected battery and now wont idol at all after warmed up. Tried driving for about 10 min, did not correct it. Any suggestions?
