Dear Forum Members,
One of my 2003 corolla LE seem to be very rough at higher RPMs. For example when accelerating from a stop, I can feel roughness and vibration past 2500 RPM. Also it seems that the car is not smooth at higher RPMs. However, the engine is very smooth at RPMs below 2500 no matter which gear.
I have cleaned the MAF sensor and reset the ECU by disconnecting the battery. Checked the spark plugs and they are clean. The car has 82K miles on it.
Thanks for your help.
