22re's are junk
There, I did it, you happy firehawk jay?
Check the ignition module ignitor thingy, mine was shit and the truck idled like shit but ran ok under load.
Timing could be off, timing guides and timing chain replaced recently?
My 22re had all loads of issues, then it blowed up, rebuilt it, new ignition thingy, new pistons, rings, bearings, cam, etc. ran decent after that, until it died on the way home for the new owner, fucking peices of shit.
