Evening everyone,

Currently my daily driver 96 4Runner V6 3.4 Supercharged 5 speed manual. Whats going on with it has me stumped... A very slight misfire that only happens from what I can tell in 5th gear at 2900-3000RPM. I have 0 codes and also 0 pending codes, for about 3000 miles now i've noticed this going on. As far as what i've done to being the process of elimination in trying to locate this issue is, clean throttle body, clean MAF, replace denso spark plugs and denso wires...


Next plan is to replace the fuel filter just for giggles? Along get a compression on all cylinders.
No signs of head gasket problems...
New motor has 50k on it.
Full wide open throttle is just fine, cruising in town is fine, and cruising at 65mph is fine but that 2900-3000 freeway speed is a very slight tiny misfire.

Any ideas?

My buddy has a problem very similar. Interested to see where this post goes.
