there is no reason for a stock 22re with a stock cam to be loping like it has a big cam at idle.
wait it was louping jrock said spuddering this is different Not to thread jack jrock jus wanted to put out what i have tried with mine as now our problems sound the same my motor had a fantom loup at idle as well ihave doen everytthing my hole underhood is new everything only 10g's on the motor and everything was new in it when it was rebuilt and i still have this loupe sometimes and others its fine ive been seeing more ppl having this issue i even replace my ecu and fuelpume i have it pretty much narrowed down to a wireing problem somewhere possibly a ground issue ( does the ecu ground through the truck body where it is bolted in place in the cab)
