Misfire on 93 Toyota 4Runner 3.0
I have a 1993 Toyota 4Runner 3.0 that has a misfire when it's cold around 1500-1800 rpm it does it. It almost feels like it has a misfire all the time even when it's warmed up no matter the rpms. I know the 3.0s are slow but something just doesn't feel right to me. I have brand new ngk plugs in it aswell. No clue to as old the wires are. Thankyou !

Shoulda done a compression test while the plugs were out.
Tight valves are one of the usual suspects on these old 3vz's
It;s a pain to adjust the valves on them, so nobody ever does until it's too late and a valve job is the only solution.
