Ok , anyone have part number for the outer seat track bolt cover on both front seats? I searched and found the front ones can’t seem to find what i need. You think it would be on actual part . Also need part number for spark plug wire separator? Two of mine broke. Next thing is , I’m getting a slight ping at just over 2000 rpm under a little load. Just started a few weeks ago. So far i sea foamed the intake and gas. Changed wires and plugs to recommended NGK. Changed pcv valve , air filter , and cleaned Maf for the hell off it. I even put 91 octane in it . Fuel filter was changed a few years ago. Any info is appreciated.

Try replacing the upstream O2 sensor, it's $50 on Amazon. Just be sure to get the right one depending on year, and if 4WD or 2WD. The DENSO part finder website is helpful.
On 2nd Gen 4Runners, Toyota recommended replacing the O2 sensor every 90k miles. If you don't think it's ever been changed in that amount of time, go ahead and do it.

Yes, just the upstream. You might even gain some MPG's back if it was fouled up but not throwing a code. Happened on my rig.
