How can i fix my car that cannot maintain speed when it reach 2100 rpm.
I have to floor the gas to escape the hiccups and then let's say at 70 mph it will start to lose speed. I constantly step on the accelator to keep up with the flow of traffic. Otherwise, if I let the speed to come down, it start********. Beyond 2100 rpm, it is okay.
Please help as I already change mostly everything like Air Mass Flow sensor, spark plugs, wires. fuel pump, fuel injectors, ignition coil, air filter and fuel filter.
