Hey everyone, just finished up a 17 hour straight drive from Los Angeles to Seattle in my 91 Camry 4cyl auto 3SFE. The Camry did amazing, however I noticed one small issue after I would start the car after turning it off to fuel/get food. After starting, it struggled to idle, seemed very low rpm’s and felt like it was on the verge of stalling. After even just tapping the gas it would idle like normal. Any ideas on what to check? TIA

update: the next morning when starting there was no stalling or low rpm issue. Actually the opposite. Very high rpm’s that didn’t drop after a few minutes .

Two main possibilities - stuck/dirty IAC (idle air controller) or something is up with the cold start injection system.

I'd start with a good throttle body cleaning if you haven't done it before. The IAC bolts to the bottom of the throttle body - make sure you use a good quality screwdriver (JIS cross-head if you can) to remove the screws that hold it on to the throttle body if you are going to remove it.
