1994 toy runner

I’ve got a 94 runner 3.0 v6 5 spd 4wd, that runs great at idle, great at highway rpm but stutters a bit at mid range under a light load. i.e. very unsmooth accel from 1200-2600 rpm. like accelerating in 2nd gear after turning a neiborhood corner. Lots of people have looked at it and no solutions. It is worse with A/C on (additional load). Thanks for any insight!

Have the MAF sensor tested. It is an expensive replacement part, so don’t go chasing the problem by throwing parts at it. My manual has a procedure to test for smooth readings with a digital multimeter. Any Haynes manual should have the same test.

Thanks, I’ll give it a try
