Default Very picky & preferential stumble

My '96 w/ 2.3 & 5 speed has a weird hiccup. At EXACTLY 2500 RPM (in any gear) the motor stumbles momentarily. At 2600 it is smooth. Around 3200
the motor really starts pulling nicely. Replaced the timing belt and it has new plugs, wires, and coils. Any suggestions before I install a V8 out of sheer frustration? Thanks from a new member(ME)

Do a search on stumble
Sometimes I find answers by searching for different words related to my problem.
Obviously not all members are looking at the posts daily, though some may know the answer.


Good Luck

I have to tell you that I have never heard of a truck's engine stumble at one RPM only and smooth everywhere else along the rev spectrum. It makes no sense to me.

2500 rpm exactly- in any gear. Momentary. Really odd.

to have the stumble at that exact rpm every time no matter the gear sorta makes it sound like a computer / electrical type problem.
