1999 Toyota Camry 6 cyl Front Wheel Drive Automatic 244500 miles
While driving 55, 60, 65 mph engine will start to slow down and sometimes even speed up some. I have replaced wires, plugs. Air filter, fuel pump and screen. The egr valve ports are clean-even blocked the valve port but no change. IAC valve was replaced one year ago due to stalling at idle. Engine idle is fine as is excelleration to any speed with no miss, and no trouble codes. Also cleaned the throttle body. Also replaced boots under coils (3).
have the same problem?
