3.6 Litre engine, had engine torn down at 174 000 miles, 10 000 miles in on the rebuild. About 5000 miles I started to get a hesitation in low idle, runs great other than that. Took it back to the machine shop that did the engine and they said the could no nothing without and engine light and code to tell them what is wrong.

Ideas on if the engine rebuild could have caused this and what it might be?
 
Do you have Jscan or know someone with a decent scanner to watch the live feed from your engine?
