Integra :: 1987 Rough Idle / When Stopped RPMs Drop Below Normal
I have done everything I can think of to this car. New; plugs, wires, distributor, battery, fuel pump, fuel filter, relay, and electrical lines to fuel pump. The timing belt is fine. The car has a rough idle and when I am stopped the RPM's drop below normal. Now it won't start. What can I try now?
View 1 RepliesSaturn - SL2 :: 1999 - Engine Rev Up To About 2000 RPMs While At A Stop Then Drop Down To About 650
My '99 Saturn SL2 has from time to time in the past year or so had brief bouts where the engine will suddenly rev up to about 2000rpms while at a stop and/or drop down to about 650rpms combined with surging and stalling while moving. The Service Engine light would typically come on in conjunction with these spells, but then a few days later, things would be back to normal and the light would go off. The episodes seem to correspond with weather that has high humidity, but not necessarily extreme heat. Once or twice when the heat was above 90, the car quit completely and wouldn't restart for several minutes, but that was last summer.
About a month ago the car, which is normally parked in a garage, spent the whole weekend outside when we had some extreme rains (in air temps only about 60s or so). Since that weekend, the car is running frequently with the issues previously described, especially the surging and stalling while driving. It will feel like the timing of the fuel is all out of whack, will shudder and run hard, and then it will suddenly correct itself and run normally. A friend has a code reader and the codes that came up are 404 and 1404, which indicate the EGR valve. We replaced that with a new one and put in 4 new spark plugs, but the problem still persists. I believe the fuel pump is in the gas tank, so from other things I've read, a vapor lock may not be the problem since the fuel is being pushed.
Dodge - Dakota :: 1996 - RPMs Will Drop To Near 0 Within About 20 Seconds Of Coming To A Stop
I have a code scanner which indicated that I should change the MAP sensor. I did that, and just for fun changed the idle air control valve and throttle position sensor. Now the idle is extremely smooth in park or neutral, but once I'm in a moving gear it's up to the same shenanigans, antics and tomfoolery I described in my original post: 96 Dakota SLT idles rough & stalls. So I have a 96 Dodge Dakota SLT 3.9 4WD. Anyway, it idles relatively smoothly at about 700 RPM in drive or neutral, but if I'm in a moving gear and need to stop, the idle is extremely rough. Usually, the RPM's will drop to near 0 within about 20 seconds of coming to a stop. It will typically recover and continue with rough idling and near stalling a few times, but within a minute or two it stalls. A few additional details: it starts right up again after falling, it doesn't make any difference if I start it cold and drive immediately or drive it for an hour before coming to a stop, the same thing happens. Anything that looked suspicious to me has been changed (drivebelt, spark plugs & wires, distributor cap & rotor, pcv valve, idle air control valve, and, of course, the air freshener).
View 1 RepliesHonda - Accord :: 1983 - When Rolling To Or At Stop RPMs Drop And Stalls
I have a 1983 Honda Accord (manual with nearly 200,000 miles) when rolling to a stop or at a stop rpms drop below 1000 and it stalls out. I can start it back up without hesitation.No hesitation at initial startup or after sitting short or long time, it idles while in park rpms about 1000.When I feel the engine about to stall while rolling to a stop or at stop, if I put my left foot on the brake pedal, slightly step on the gas pedal with my right foot it prevents the engine from stalling. At stop if I put in park, rpms raise and don’t need to give it gas.
I'm unable [& unqualified] to work on my car. Given I drive only about 1,000 mi year; my alternate form of transportation is a bus or kindness of friends, I’m on a limited income, cannot afford to buy/ spend more than 2,000 -- my question if 2-foId, 1. is it possible that something it is nothing major and worth repairing/replacing (ex. air control/idle air bypass valve, a dirty throttle body or even carburetor)?2. Or, as discussed with one mechanic, since the car is 33 years old, during or soon after repair other problems (dried out vacuum hoses or major) will follow. Plus, parts can be difficult if not impossible to replace as a I spoke to mechanic pointed out.Given the car’s age is it worth repairing?
Ford 7.3L Power Stroke (1999-2003) :: F350 - RPMs Won't Drop Below About 850 When Come To A Stop
Have a 2003 F-250 with 174,000 miles. Recently replaced CPS and ICP and it's running much better. It normally idles at about 700 rpm. Lately, after driving for any distance above ~40mph, when I come to a stop, the rpm won't drop below about 850 rpm. If I shift to neutral (automatic trans), the idle drops to around 700. At the next stop sign/light, it's back up to around 850.

View 1 RepliesIntegra :: 94 Teg - Drop And Surge Throttle Cycle
A few months ago my teg started idling a bit funny. Its got a chipped ECU and has always idled very low (500 - 750 rpm) once warm.
In the past few months however the revs have started fluctuation or surging. Basically once the engine is warm the revs drop right down to nearly 200 - 250 (the needle actually drops off so its hard to tell ), then the engine bounces back up to around 500 rpm. It then does this non-stop if I leave the throttle alone.
Ive found that resting on the throttle tends to solve the problem as I'm forcing the system to run constantly, however when letting off the throttle (or dropping out of gear), she drops right down gets really ragged then bounces back up to ~500. The drop and surge cycle takes roughly 2 seconds.
Ive taken it to an auto electrician who sat on it for 2 weeks and eventually shrugged his shoulders. I've heard that one factor could be the O2 sensor, however another camp has said ECU and yet another said throttle sensor.
Details of the car are:
94 Honda Integra (GS-R model)
B18C (Gen 1) motor - Enlarged throttle body, Gizmo chipped ECU, better breathing with a pod etc.
Camry :: Rough Idle - Vibration Start As Soon As RPMs Drop A Little
I've made posts about a rough idle before now I noticed something new about it. I noticed when I approach a red light the vibrations don't start immediately. They start as soon as the RPMS would drop a little. They stay above 500 but it seems like it's below 750. As if the engine is slightly starved from power? Now i'm wondering if it could be related to another problem I have.
Whenever I start the car, the battery light flickers until the car is started all the way. This is on a 2007 Camry 4 cylinder. So far everything iv'e done is: New NGK Spark Plugs, NEW OEM mounts (all 4) Seafoamed the engine, Seafoamed the throttle body, cleaned the MAF sensor, New air filter, and cleaned the air filter box, replaced the PCV Vlave, new belt, new alternator (duralast), and a new battery (from autozone).
Lumina :: 1992 - Stalls Intermittently And No Start / RPMs Drop Rapidly
I purchased a 92 Lumina Euro with a 3.1 and 101,400 miles on it a little over two weeks ago. It has been having problems since I got it.
It stalls intermittently, typically after I drive to work, shut it off for two hours, and then start it to go to my next client(home health aid) sometimes it stalls right after starting it then, and/or sometimes when put in reverse and/or drive and occasionally at stops signs after the aforementioned problems occur. It has also stalled out twice after highway driving after the car is shut off and started shortly afterwards, for instance, when I ran into a tobacco store for some cigs.. After the problem occurs it usually drives ok if I continue to drive it awhile even if I shut it off for a short time and restart.. I added some fuel injector cleaner when I filled the tank but it didn't work.
After about a week of the stalling issues the car refused to start after dying and didn't start for two or three days. As I was unable to get an answer from the dealer my step-father, who went with me when I bought the car, called him and he said if I could get the car there he would fix it. So I borrowed a bundle to have it towed the 25 miles or so to the small town car lot.
His mechanic supposedly fixed it by replacing the TPS and the dealer informed me that they had cleaned the throttle body before I bought it and apparently the TPS needed replaced to. However the issues again started after one day of it running fine. I tired to get a hold of this guy again and again I get the voice mail and no return call so as soon as I got off work I drove it over there and again he said he would fix it. He had it for three days and I again tried to get a hold of him without success and he again answered the phone for my step-dad and told him they had ordered some kind of module that would be in Monday. So Wednesday he calls me and tells me that they didn't replace this module because when they took it out it tested good five times but they noticed some gunk build up at the contacts of the wires that hook to the module and now the car was fixed. Why did they order the part before testing??? This doesn't make sense so it throws doubt on what the man said. I went to get the car and when I got back to my town and went to get those cigs it died twice after restart and put into reverse. That was two days ago and it has been dying once or twice each day since then although it is somewhat better than before as it isn't taking as long for the idle to even out at sufficient rpms after I throttle it at idle or drive awhile. BUT now it seems to be sucking the gas hard and I am wondering if this guy just did some jerry-rigging because he sure isn't fixing it.
A few more details. The rpms drop rapidly when this occurs, it has a couple of times had a rough idle at the same time but more often the rpms drop and it dies.Sometimes if I use the throttle and keep it up around 1000 rpms for a short time it won't die. I have smelt a burnt smell a couple times when I shut the car off, like electric burnt, not oil burnt or stinky exhaust. Lets see, I felt a very brief loss of power feeling when driving on the highway on two different occasions, so brief that it was barely discernable. It runs over the halfway point on the temp gauge after driving awhile in town, seems a little hot to me but I read these cars don't kick on the fan till 220. Sometimes the rpm bobs a little up and down at idle and slow speeds and once the battery power dropped and popped right back up when it was idling funny and when it had that no start an acquaintance tested it by putting a screwdriver in a plug wire and pointing it towards the engine as I cranked it and he said it had no spark and it did crank every time I tried to start it during the no-start condition. It has also done a bit of surging from time to time when the prob happens. The car is recovering from the stall condition quicker than it did before since this last "fix" but still stalling.
Camry :: RPMs Go As High As 3000 For A Couple Of Seconds And Then Drop To Normal On First Start Up

View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: After Start Up RPMs Drop - Stalls Out Then Idles Rough?
2003 7.3 excursion.. The truck starts every time revs up and idles about 3 seconds then the rpms drop and it tries to stall out catches itself then revs backup and idles rough similar to if you have got air in the fuel lines from changing the fuel filter.. About 1 in five times the truck will stall out and it starts and immediately and idles rough but the rpms and everything runs at speed and rpms don't drop again! This is a reman engine/transmission recently installed.. The mechanic who installed it was unable to figure the problem out.
View 6 RepliesAcura - Integra :: RPMs Fluctuate Up And Down
Lately, my 1990 Integra has been idling VERY low. Some mornings, while idling at a stop, the rpms fluctuate up and down to the point where it almost dies. Is it just cold? I live in coastal San Diego, so it's not freezing here. This morning, had to keep my foot on the gas to keep the car from stalling before getting home from dropping son off at school. It died in the driveway. Started up just fine right afterwards, but idled down to nothing. Now it idles okay, but at a pretty low rpms, like usual. NOW, the battery, a SEARS Diehard Silver, is near the end of its usable life. Prorated 84,000 mile replacement warranty, but I have had it for 8.5 years and have 1 82,000 miles on it. YES! I have been meaning to replace it, as it is leaking some nasty stuff at the terminals, but wonder if the weird idling is a symptom of something else, since the car still turns over.

View 6 RepliesMazda - Tribute :: Rough Idle When Cold / RPMs Drop Close To Stalling When Stopping At A Light
I have a 2001 Mazda Tribute with 150,000 miles that is meticulously maintained. This past winter (as far as winter goes in San Diego) the engine would run rough and the rpm's would drop close to stalling when stopping at a light for the first 2 or 3 miles. After that the engine has warmed and there is no problem. Could this be the intake gaskets needing replacement. This only happens on a cool or damp, rainly morning.

View 5 RepliesDodge - Caravan :: 2005 Hesitates Several Times When AC On And Stop At A Light
I have 05 Caravan, 4 cyl, 115k. Runs fine (just got back from a 2000 mile trip) that seems to have a quirk or something with the AC.
When I have the AC on and stop at a light, it feels like it hesitates several times. I almost think it'll stall (never has). I usually end up turning off the AC while we're at the light, and start it back up when I accelerate. When the AC is off, there is no hesitation. Also, If I put it in park, and we have the AC on, no problem. I rarely, if ever, have the recirculation going.
One thing of note: I usually wait until I'm out of our neighborhood and on the main street before turning it on. That means the windows are down until I turn it on. When I do, occasionally I hear a sound that best can be described as similar to the sound of loosening a tight lug nut. Still, as long as I'm driving, there is no hesitation and it cools fine.

My 1994 Acura Integra makes a buzzing noise exactly between 3000 and 3500 RPMS. It sounds kind of like the sound a circular saw would make cutting wood. It only happens when I am accelerating through that range. Also, sometimes after driving for a while, it doesn't last as long and the noise stops around 3300 RPMS. I've checked the heat shield and it seems to be fine so I don't think its that. What this could be caused by?

The dealer says it is throwing a P3000 and P0A80 codes. I asked for subcodes, the dealer doesn't know what I am talking about.
The dealer wants to replace the hybrid computer for $900 and if that doesn't fix it they want to replace the hybrid battery for $3500.
