Idle fine, checked all the obvious, 1 old code from busted exaust. Cleaned all changed oil and ran throttle body cleaner through v6.
still shakes when you atempt to drive it. In gear its a shaker, new plugs and wires and can not figure out whats up with it. Feels like a bad miss or a dead cylinder when powered.

Check the fuel presure. May be enough to idle but not any more rpms.

Checked that as well, all the obvious stuff was done. Going to clear computer codes again and then see what happens, its got all the ear marks of a dead cylinder. Yet you can rev the hell out of it when in neutral and it sounds normal. Nothing in oil or rad. Does not make sence. Thanks

What was the fuel pressure?

Clearing the computer? Does nothing for your issue. What was the codes?

Start at basics here with a real fuel pressure test with a guage
