Re: Hesitant acceleration persists

OK, new plugs and wires.....you say coils were within range....do you mean resistance wise? You should do a coil output test with a spark test.....

If ok, then have you checked compression? Does this happpen at idle or when under a load?

If at Idle, I would check valve springs, for a broken spring.....

If ok, could be an injector problem.....

Assume 3.8.....losing coolant?
