Here are the particulars:
Only starts to ping once good and warmed up, it's not super pronounced but you can notice it.
Here's what I have done so far:
- New NGK Toyota approved plugs gapped to .032
- New Toyota Plug wires
- New Denso Cap and Rotor
- 2 Full cycles of Redline Fuel system cleaner
- Checked timing (it's correct when jumpering the diagnostics points indicated) 3 degrees BTDC. When jumper is removed timing should sway in between 2 to 15 BTDC. At idle it tends to stay toward 3 to 8 degrees.
- New PCV Valve (Toyota)
- Tried running premium fuel (Did Not make a difference at all)
- Tested EGR valve and passes fine
- Just had an emissions test and it passed with flying colors
I don't know if it would be worth it to take it to the Toy Doctor here in Littleton CO and pay the $90 just to check it out, I'm afraid they may just give me a bunch of expensive fixes! I guess I may not have a choice but was hoping you all may have some other ideas?
Can an air filter make a difference?
This air filter is I would say in marginal shape.
Thanks again in advance! I'm still trying everything I can. I know that pinging is hard on the engine and need to figure this darn thing out!
