engine has 241,000 miles but runs great.

You realize its old, but dug it up anyway??? The Dug up the Old Azzed Thread of the week AWARD right here!!!

You could have started a new thread and linked back to this to do it right. READ: Old Threads/'Necro-Bumping'

Answer, it is an I5, they are not inherently balanced, when the AC clicks ON it changes load and rpm and smooths out. Same thing if you get rpms up off the idle stop, it is how the I5 balance weights work. It is a funky motor, but puts out good power and low end torque.

This old thread is put to rest.
