2004 Accord : RPM Doesn’t Go Above 3000

I have a problem with my 2004 Honda LX, the rpm doesn’t go above 3000. Can you tell me why this is happening ?

Answer : It’s most likely your Throttle Position Sensor (TPS) meaning your cars computer doesnt know how far your pushing the gas down or how fast you want to go, so the cars computer doesn’t know the proper air-fuel mix to put in the engine when you go above 3000 rpm and need more power.
Also it could be the idle air control valve (iacv) meaning your engine not getting enough air at idle. It’s causes the rpm to jump up and down between where it should idle and like 1 or 2 grand.
Best thing to do is check your fluids especially your radiator fluid. If its low it will idle wierd.
