Wont rev past idle

Will it rev up when you are out on the highway? If so, newer cars have a rev limiter to protect the engine if you are not driving the car. If you have an electronic throttle sensor, it may be bad. Scanning the obdll system will give you that information.

Most cars have a rev limiter built in and will not let the engine goe past 4000 rpm's you may want to change out the spark plugs as often if it has flooded just once the plugs do foul out

IF you have a carby then take it apart and clean it out as all the throats are not working properly including the accelerator pump.

You need a repair shop to diagnose
ALL the codes & resolve ALL the cars
problems,not a guess without a vehicle to test

Accelerator pedal position sensor needs testing.

check fuel pump pressure first ,

Have someone check your fuel presure, it may be time to replace your fuel pump. It worked for me.

My vg30 dnt rev more than. 2200

that sounds like a fuel delivery problem. either the filter is clogged or the pump is not delivering the right pressure. i assume you have no check engine light. this would not set one but other problems like sensors would. being 11 yrs old i would not be surprised if the fuel pump was worn out. good luck

try your maf sensor
