Ok so some of have read my past post on my 94 toyota pickup (22re) with egr problems egr is fine did all the test, and pinging! i have fixed all issues! All vaccum lines are hooked up right. Im still having pinnging problems. Anyone have a clue what might be going on? injectors havent been touched. Running ngk g power plugs and a 180 degree t stat. I dont know if any of this info would help or what not. thanks guys

Your timing is probably too far advanced....what kind of condition is your coil, igniter, wires and everything relating to that in?

my 90 22re was running rich and pinging wouldnt pass smog .the shop diagnosed and fixed it .they replaced the o2 sensor and found 2 vacum lines swithed that went to the egr.are you getting any codes ? that might help diagnose itgood luck with that.

It's in the FSM(you can download here) or on the sticker under your hood.

Engine has less than 4,000 miles on it! New plugs,wires. Ignitor isent new and coil is either. Timing is set to 5* tdc with timming jumper installed! Could I try and set the timing to 4* or 3* to see if it will go away? Any long term effects if the timing is not set at stock settings? O2 sensor is also new.
