jmeeter Posted February 13, 2007 Posted February 13, 2007 Hey everyone, Today I just bought a 1994 Honda Accord fo $900. The thing is in excellent condition, with 137,952 miles on it. Brakes, engine, steering, etc work fine. At a stop light, however, I put the car in park so I could reach in the backseat to grab something. I noticed that the RPMs starting jumping up and down from 900 to 2,200 RPMs. As soon as I put the car in drive, it stopped. I put it in neutral, it started. I put it in drive, it stopped. I spoke to a "mechanic" at Wal*Mart when I was there grabbing floormats, and he said it sounded like the Mass Air Flow Sensor was out of wack. Does this sound accurate, and how much am I looking at to get it repaired? Thank you, Jordan Meeter
cranny Posted February 13, 2007 Posted February 13, 2007 doesnt have a mass air flow sensor , lol. could be your iacv , or try topping up your coolant perhaps its low.
jmeeter Posted February 13, 2007 Author Posted February 13, 2007 What is iacv? Sorry, I don't know much about cars.
Monty Posted February 13, 2007 Posted February 13, 2007 Mine does something similar when I'm cruising at about 70-80. but it only bounces about 200-300 rpm. At first I thought it was because my car was trying to pull but even on downhills it does it.
90IntegraC1 Posted February 13, 2007 Posted February 13, 2007 idle air control valve....on the back of the intake manifold
Monty Posted February 13, 2007 Posted February 13, 2007 idle air control valve....on the back of the intake manifold think that could be my problem too?
90IntegraC1 Posted February 13, 2007 Posted February 13, 2007 ha i've never heard of fluctuating rpm's during highway driving.....couldn't help ya
cranny Posted February 13, 2007 Posted February 13, 2007 sounds like surging , it could be iacv. could be a couple things.
Joe W Posted February 13, 2007 Posted February 13, 2007 My crx does the same thing even after i replaced the iacv and did a radiator flush. Its really annoying.
90IntegraC1 Posted February 13, 2007 Posted February 13, 2007 how's your distributor? back in the day when mine was AT the rotor kept getting water on it and corroding, which then caused the rpm's to fluctuate all the time, then it would die about 2 weeks later.
Joe W Posted February 13, 2007 Posted February 13, 2007 how's your distributor? If you are asking me mine is fine only replaced the cap and rotor when tuning up.
jmeeter Posted February 13, 2007 Author Posted February 13, 2007 So let's say it's the IACV - Can this be repaired, or will it most likely need to be replaced?
boostedb16 Posted February 13, 2007 Posted February 13, 2007 If it is the IAC valve then yes you have to relpace it. I wouldn't take a chance on trying to clean it. I saw one guy clean one at work w/ throttle body leaned and it ended up ruining the IAC valve and the MAP sensnsor.
jmeeter Posted February 14, 2007 Author Posted February 14, 2007 http://cgi.ebay.com/ebaymotors/OXYGEN-SENS...1QQcmdZViewItem I'd want something like that, right? Or: http://cgi.ebay.com/ebaymotors/Honda-94-97...1QQcmdZViewItem
90IntegraC1 Posted February 14, 2007 Posted February 14, 2007 yes, buy the IACV before the O2, so you can replace it and see if it fixes your problem, if not, buy an o2.
