Idle Issue

After I installed the SW headers and the 5Star "87 performance" tune... the engine can't seem to idle correctly. It seems like it trys to idle at about 650rpm and then has issues and jumps to ~900rpm for a second and then trys to settle back down to 650. it seems like it just does this when it warms up (but not 100% certain.

Tried to video it with my phone...

Thoughts?

Could be a few of things. loose intake air tube unmeasured air getting by , if you pulled the battery you need to go through a new KAM learning process.

Is that ticking I hear... Might be Canister purge valve..

My truck does the same and the engine is completely stock

I've been noticing the same thing with my truck here lately and it's completely stock.

roughly 50,000 miles

From my limited experience.. Those with aftermarket CAI tend to see failing canister purge valves sooner. Those that are running stock intakes 40-60k miles seems to be the trend.
