Re: cluster? or a simple sensor?
First, change the fuel filter, sounds like it is fuel starved. You're right, the fuel pump will generally wither work or not, a clogged filter will only allow a certain amount of fuel through, limiting RPMs

Nothing, you have hit the rev limiter. The up and down is the computer controlling the rpm. If you drive it, it should rev past 3,000. The computer is designed to keep free wheeling rpm to that level. It will only allow a higher rpm if vehicle is in gear and moving with a load.
Hello ,,i have run into a situation some what the same with another unit but i describes it quite well, i found a piece of fuel line that some one had replaced and the hose was not rated for gas, the line swelled on the inside and choked off the fuel flow at high demand, i`e pulling hills and hi RPM`s
3000 rpm? This is pretty high for idle. You need to have the stored code read from the ECM. Usually this is a simple O2 sensor but with it racing to 3000 rpm I would have this diagnosed by a tech at a shop.
Well all cars idle at 550 rpm to 700 rpm depends on engine but it sounds like you throttle body is not shutting down .
yes could be idle sensor or you could have a hose come off the intake manifold so bypassing the body valve, ,check throttle cable for free play when not going..check for hoses off /crackedand leaking air/or hose off the engine block either big or small ..
If you dont have a code reader go to Autozone and have them read them for you. it sounds as if you may have a defective sensor. It may be a simple cheep solution to try to clean your mass air flow sensor. You Can do this by taking some brake parts spray cleaner to clean it up. the brake parts cleaner dosent leave any residue so it wont harm the sensor. If you dont know where the sensor is located it is usually located just after the air filter box.
Hi, Did you notice the motor actually reving higher when the tachometer was reading a higher rpm.. If it was it could be your transmission slipping.. Set your cruise control and listen to your motor while the tachometer starts moving erratically.. Good Luck
