Hesitation.

[CrimsonEclipse]

2003 B2300 2.3 5 speed 70k

At acceleration with engine rpm at 1900-2200 I have hesitation and it is getting worse. It's not a problem at higher rpm's and seems more pronounced when it's not fully warmed up. I can't figure if it's a spark problem, fuel problem or a computer problem.

I've tried injector cleaner, new plugs, new air filter.
Next is a new fuel filter and spark plug wire harness.

Is there anything I'm missing?
Is there anything else I can (should) check for?

Thanks.

Solved.

Solution:
Ignition coil.

I needed to perform a tune up (if you can call it that) anyhow.
