Car Forum / Honda Cars / September 2005Engine racing
Hi all, I left my '97 Accord sitting in a driveway for 12 days, and when I got back, I found that the engine had started racing. Frequently when I'm driving, it's like cruise control is engaged for 2-3 seconds after I stop pressing the gas, and when I take the car out of gear (to change gears, for example), the engine races, usually to around 4K, sometimes almost into the red zone. Does anyone have any idea what could have happened while the car was sitting still that could cause this? Many thanks. -Joel Hoffman > Hi all, > [quoted text clipped - 11 lines] > > -Joel Hoffman frayed throttle cable sticking? >> I left my '97 Accord sitting in a driveway for 12 days, and when I got >> back, I found that the engine had started racing.

Also, I've noticed that tapping the gas tends to bring the engine back down to where it should be. -Joel ---------------------------------------------------------------------------- Free 35mm lens/digicam reviews: http://www.exc.com/photography ---------------------------------------------------------------------------- >I left my '97 Accord sitting in a driveway for 12 days, and when I got >back, I found that the engine had started racing.

One more data point: I've noticed that tapping the gas tends to bring the engine idle back to where it should be. Could a clogged something cause this?

Could a clogged something cause this? frayed cable can do this. it the pedal snaps back, it's got more velocity and therefore momentum than a gradual release. check both ends. it's a common problem on high mileage cars - but you don't reveal that vital data. before asking more questions, it might be handy if you tried the suggestions made by all posters & report back on whether they helped you finger the problem. otherwise we're all shooting in the dark. > Thanks. > [quoted text clipped - 3 lines] > Free 35mm lens/digicam reviews: http://www.exc.com/photography > ---------------------------------------------------------------------------- >>I left my '97 Accord sitting in a driveway for 12 days, and when I got >>back, I found that the engine had started racing.

Maybe not a frayed throttle cable, but possibly a gummed one... something collected on the cable where it slides into its sheath. Depending on the environment it's in, it's more than possible for something to settle while the car was parked. --- avast! Antivirus: Outbound message clean.

It gets condensates of gas vapor that gums it up. That's why sitting can make it worse. Should be done occasionally anyhow. Use google to find a DIY answer.

I had this happen to me on an old VW and it turned out to be a throttle cable that had worn through it's teflon liner (200K+ miles) and in cold weather ice was forming on it and binding it. nate >> Hi all, >> [quoted text clipped - 11 lines] > > Clean the throttle body.
