07 GX and lately has had a strange idle. At stop in gear the norm is 700rpm but it will drop down to 500 then randomly change back and forth to 700 or 500. A/C is off. Lately on highway cruising around 55 and if you are barely touching gas pedal you can feel the change just like the idle rpm. If I slightly press gas then let go the tack will drop down to 1000 then jump back to 1500. Something is confusing the computer. I just cleaned the MAF sensor and throttle body with no help.
anyone have this issue? Thinking it is ether MAF or throttle position sensor.
