    thats not the issue fixitman im not opening throttle all the way im just trying to get the car to actually go when i push the gas peddle. its not trany problems either cause it bottoms out power in every gear. i was told to start by replaceing fuel filter, then do a compression test on fuel line and then fuel rail ie pressure regulator valve, also try cleaning lenum what ever that is, also was told to take appart the throttle body and clean it up, another one was said to check vaccume, and somone else told me to replace spark plugs, wires, dist and i did that already i also replaced the mass airflow sensor since it was broke at the sensor plug. all i want to know is if somone else has had this kinda problem where the car idles but wont accelerate. and if they have let me know where to start and compare there problem with mine and there cure with my solutions.

The engine has a rev limiter to keep from blowing engine up with too much rpms at idle.

    Have you checked vacuum yet? You may want to because you may have a stopped up exhaust system which when you check with a vacuum gauge and you open the throttle the vacuum goes to zero or very low. If your exhaust sysytem is operating properly when you open the throttle the vacuum will go down shortly but come back up pretty quickly. Also you may want to check the rubber boot that goes from the mass air flow sensor to the throttle body for air leaks because that can also cause alot of problems. Hope this may help you. Let me know if I can help any further.

High reving engine


Probably a sticking throttle cable - when this occurs, look under the hood to see if the throttle lever on the throttle body is fully in the rest position.

Over reving


Can be a number of things (check all of these):

  1. Stuck throttle linkage or accelerator pedal;
  2. Loose butterfly on throttle body;
  3. Stuck or malfunctioning idle air controller;
  4. Loose or damaged throttle body or bad throttle body gasket;
  5. Cracked intake manifold or bad intake manifold gasket;
  6. Bad ignition control module.

My engine revs and trys to take off while i am sitting still, the car would be in drive and my foot on the brake, It revs up and sometimes when i let off the break it surges forward then shuts down in...


The idling may be a loose connection to the "idle air control valve". if the control valve connection is secure, then it could also be a bad Throttle Positioning Sensor (TPS). To test the TPS, tap it with a screwdriver while the engine is self-revving, and see if the reving changes when tapped. if its not the TPS, then try cleaning the throttle body.

Engine speed hunts on idle. Auto trans slow shift.


The fast idle valve is inside the throttle body. Sometimes it backs out and needs turned back in (it's threaded). This will cause the loping idle.

Get transmission filter changed with new fluid. Honda does not recommend transmission flushing.

Car dies when slowing down or stopping


Disconnect the air hose going to the Idle Air contorl Valve and plug the line with a small screw.
if the problem of the idle goes away and the car runs smooth and doesn't stall at stops, it's the air control valve housing sensor, it's basicall the whole unit thats no good. If it still stalls, clean the throttle body housing and all parts in where the air gets sucked in, put a rag underneath to keep the dirt from dripping down, start the car with somebody inside the car reving up the engine to 2000rpm's to 2500rpm's, then spray in to the throttle with burst of throttle cleaner and you will see the gunk keep coming out, you may have to change your spark plugs after this is done also.

Good Luck BigWillie
