Probably the timing belt jumped. If you have over 100,000 KM it needs replacing. Hope this helps. When timing is out, it will idle high and rough.. :-) Cobra

I just bought a 91 honda accord se and when you go to stop it stalls or suts off. any ideas of what may be causing this


Check your 91 Accord's ignition coil. The coil goes bad at apprx. 150k miles and cause the car to run rough, hard to start(long cranking time) in the morning, stall after the vehicle has warmed up, cut out while driving and backfire horribly when accelerating from a standstill.

Truck loops during idle and eventually stalls.


Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

My car threatens to die during idling...the rpm drops down low and then goes back to normal. It started doing this during driving too. I just had the fuel filter and a few other fuel related things...

ROugh idle


there are 2 things that usually cause this, one is a dirty intake idle control valve and the other is hard engine mounts, I would say that both most likely apply to your car. try cleaning the intake with the following procedure from Ford.
