Question about 1991 Honda Accord

1 Answer

Idle problems driving me insane

I have a 91 accord, at start up there is no problem. I can let it idle all day and it's normal, but as soon as you give it a little gas it starts to rev up and down. I took it to a "mechanic" friend and he said he swaped sensors from air and fuel including the idle air control. He thinks it could be the computer which I don't think is cheap. Any suggestions?? I did take a vacuum hose off the MAP sensor and it seems to calm the reving but it still revs none the less....... please help.

1998 Honda Accord engine rumbles and stops


rumbles?, did the RPM drop below 800 RPM? that is called idle failure
and when it does, idle can go to 400 rpm and will shake hard.
and is normal for illegal idle speeds. so post that first.
post that engine stalls
and that the RPM is 400-500 just before the stall.
then post if the fast right foot can save the stall (a key test !!!!)
if easy the ISC is sticking.
if tad hard the EGR is stuck open'
if impossible to save. then more possible (many)
ever do the 60k mile tune up this decade????,. if not why not./ now.

Why does my 91 honda accord die once i put it in drive


With auto transmitters the problem that usually will make that occur is checking on your stall converter...i would have that checked.

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.

91 honda accord cut off


Here are the most common causes of surges, stalls at stops, low 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
