SC/SL/SW :: 1998 Saturn SL2 Idle Speed Changes Low / High Then Back To Low
1998 saturn SL2 idle speed changes low, high, back to low. Some times the car dies, can happen any time a few times in traffic. Once the engines dies the idle stays low for 5 minutes, then the problem goes away for a while (a week). You never know when it will happen.
View 3 RepliesSC/SL/SW :: 2002 Saturn SL1 Won't Start - Running Rough And High Idle
Recently replaced spark plugs and wires on 02 SL1 with 209K miles. Was running rough, rough and high idle, almost died on me driving home one night. After replacing everything, car still wouldn't start. Spent some time on the forums and some suggested a leaking intake manifold gasket, so I changed that out as well as the coolant temperature sensor. Still it won't start. I am getting good spark at the plugs (coil arcs across the posts when plugs wires are off).
Really not sure where to go next with this. I can hear the fuel pump hum when I turn on the ignition, and I get a good spray at the fuel rail. Basically I turn the key and it cranks, sputters, and will almost catch, but then not. What next??
Saturn - Vue :: Service Engine Soon Light / High Idle Condition
I have a 2002 Vue with an annoying "service engine soon" light problem. When I first took the car in to have it scanned, codes 171, 172 came up, which were "Fuel too lean Bank 1/Bank 2". It also has a problem with a high idle condition where the idle will creep up to 2000 rpm when parked, and a vacuum leak. My mechanic fixed the vacuum leak and replaced the gaskets on the intake manifold plenum, reset the light, gave it back to me and within twenty miles the light came on again. It only has 20,000 miles on it....

My girlfriend has a 03 celica gt with around 126k on it. most resent it has had a problem of high idle its sits anywhere from 1100rpm to 2000rpm.

And I forgot to mention no engine lite. I've herd its not common with toyota. I also looked for vacuum leaks as well but found nothing.
View 5 RepliesSC/SL/SW :: 2000 SC2 Accelerates On Its Own When Driving And High Idle
I have a 2000 sc2 saturn DOHC 1.9 engine with just under 200k miles.
My problem is this, I recently purchased this car and was told it is in desperate need of a tune-up, being broke I decided to replace the cheapest parts first. I started with spark plugs, they are all gaped at 0.40 and all are new and the right ones for the car, ever since i changed the spark plugs the car has been idling rough (when i start it rpms go to 2500+ for about 10 seconds and drop to about 800-1100, when i shift into any gear it revs the rpms back up and they drop gradually). My other problems are that my car sounds like it is souped up and sounds like a rice rocket, when i put it in drive it starts to accelerate on its own and has reached around 40 mph at a gradual increase.
My uncle who was a mechanic said it could be the IAC, EGR or throttle position sensor, or cadilityc converter i replaced the IAC and it don't really seem to have worked much.
Ford Excursion :: 2000 - High Idle After Start Up
I purchased a 2000 4X4 V10 with 63,000 miles. It sat with very little movement for 12 years or so. I have been driving it for a few months and it now has 73,000 on it.
To my question. I have an high idle after start up. After the engine starts the idle goes up to 2K but comes back down to normal(1K or so). It takes a second or to 2 for the idle to drop. This seems strange to me. Is this normal? I've done some searching and found plenty on high idles but none seem to fit this condition.
Ford Excursion :: 2000 - High Idle Intermittently?
I have a 2000 X V10 and am having an intermittent high idle condition. I have searched the forums and found some useful info but nothing that addresses this issue. Here's what I've done. New IAC, found PCV valve hose leaking-replaced also new valve, found another vacuum leak-repaired, tested TPS and that was fine according to the specs I found. So here's my problem-upon starting engine occasionally "stumbles" then roars to life idles 8-1100rpm. Drives well till stopping at an intersection and idles 1100-1200 rpm.(lots of brake) Can pull into parking spot place in park and will idle up 1500-1800 rpm and then only drop to 1200 or so. I have checked everything I know. ALL these idle conditions are INTERMITTENT. (and yes I did check for codes "0" ) There is no loss of power.

Camry 2000 CE 102,xxx miles. My car died in Jan 14, after have P0770 for while, only Reverse gear work. The mechanics said the tranny need to re-build. I had him bring the tranny to tranny shop to re-build ($1650), then the code still pop up. Brought it back, they said the ECU needs to be reset. I had the car next day then that code pop up again!
They replaced the Solenoid E. The code is still there. Brought the car back, they took the tranny to rebuild it again. Drive the car for a day, the darn code pop up again, now they blamed on the ECU. Ok my mechanic guy replaced it at my own cost for part ($150) but the code is still there. This time they blamed on the high idle rpm approx. 1600-1800. My mechanic tried to fix the high idle speed so the tranny stop blaming other causes. He cleaned IAC valve, replace O-rings (I don't remember the location of them) then he said whenever he inserted the new ones, they start to crack!
Ford F-150 - 1997-2003 :: 2000 - High Idle With Codes
I will try to keep this short. Picked up a 2000 f-150 4.2 for my nephews first truck last night. Bought it blind against my better judgement, but the price was right. Got it home, odometer didn't work, fixed the solder joint and was happy it only had 132k on it. Heater core was plugged solid. Got it flushed and at least now its has luke warm heat until I have time for a full coolant flush and new core.
Next on my list is the high idle and engine lights. Its idles around 1300-1700, cold or hot sometimes it drops down. I only have a cheap scanner, but I have 2 codes. PO171 and PO174. Where should I start with diagnosing this? I would assume vacuum leak. Any common spots to check on these?

My buddy just bought a vr6 2001 and it has a problem! the previous owner said it had an oil leak and didn't notice it until it started ticking! ok not a big deal! we changed what was left of the oil with semi synthetic 5w20, and put a new filter on it! figured out that the oil was leaking out of the filter gasket , how he didn't notice is beyond me! now the ticking has gotten quiet BUT now it idles high! there is now CEL and the previous owner said it did not do it before the ticking! so my question is how did running low on oil, and POSSIBLY messing up a lifter or two cause it to be idling high? It only idles high in park between 1 and 2000 rpm!
View 1 RepliesAccent LC (2000-05) :: High Idle - Hesitating / Bogging Over Half Throttle
I just bought a 2002 Accent L 5sp with 37,000 miles. It ran great for a couple hours, then started hesitating/bogging over half throttle. I also noticed the idle was a bit high at this time. Suspecting a dirty throttle position sensor, I repeatedly pressed the accelerator pedal to the floor for 15 seconds with the engine off.(this will sometimes clean gunk off the contacts inside the tps) I drove the car again, and now the symptoms changed. Now it has a hesitation under half throttle, and accelerates cleanly above that. Car has not and is not misfiring. I am on the right track with the tps sensor here?
View 8 RepliesVolvo - V40 :: 2000 - Starts But Dies Unless High RPM / Stalls Out If Idle Slows
I'm struggling with an intermittent (of course) issue where, esp. if cold, I can't start my car unless I give it lots of gas. If I take my foot off the gas at all, it will stall, which means I drive this automatic two-footed (one foot on brake, one on gas) , giving it lots of gas at all times, including when stopped. After about 10 minutes it is fine, and is then good for the rest of the day. My trusted Volvo-spscific repair shop has tried replacing booster pressure sensor, fuel pressure regulator (both indicated by engine codes) and new plugs. The end result is I've got $500 into the car that does seem to run better when it starts, but the original issue is unsolved. I was thinking something is sticking with a cold start, or idle speed is incorrect, but can't figure it out. Seems like it should be an easy fix.

I have 95 ranger 3.0L revs up over 2000rpm at startup then comes down slowly to a little over 1000... Changed the IAC valve still does it... When I let it warm up I unplug the IAC and idles normal and smooth about 750 RPM so I don't think it's a vac leak... What else could it be???
View 5 RepliesElantra XD (2001-06) :: High Idle / IAC Motor Revving Up And Down
I had some problems with my Elantra and I fixed (or tried to) them all this weekend. I needed a new IAC motor, the motor was reving up and down and I tested it, then changed it. I needed a fuel injector and changed that. I needed a lower thermostat housing and changed that.
These changes resulted in the following problems. The vehicle now revs at a high idle all the time at approximately 3000. What are the causes of this?
I know that when I was burping the coolant system (changing out all the hoses and the thermostat housing) I got antifreeze sprayed all over the top of the motor.
Here is the problems that I have now. Didn't have these before.....
The engine idles at or about 3000 rpm. Constant from startup until shutdown. It idles down when you shift it into gear but that is because of the strain on the motor with the brake used.
The transmission is now having problems shifting from 1st to 2nd. I checked the fluid, its good. There is however antifreeze on top of the transmission by some sensors. Do these sensors have anything to do with the shifting?
Elantra XD (2001-06) :: High Idle / 2.5 RPM Just When Start It Up In The Morning
2002 Elantra idles high, 2.5 rpm, just when I start it up in the morning. The second I put brake on and put it into gear, it settles down and doesn't do it again until the next morning.
View 3 RepliesSuburban :: 2001 - High Idle Delayed Shifting
My 2001 Suburban, 1500, 5.3L, 2WD with 164k miles, has a problem with high idle and delayed shifting. The high idle occurs when the vehicle has been driven around for awhile. When I start it up, even when already warm, idle is normal (~600 rpm). After some time, however, it idles at 900 to 1100 rpm. The delayed shifting happens right away--almost like I have the tow/haul mode turned on.
I have cleaned out the idle air port, cleaned the MAF sensor, replaced the idle air control valve, replaced the PCV valve, replaced the engine temperature sensor, and unhooked the battery to reset things. It still idles high.
I first noticed this a few weeks ago when the battery died. After I put in the new battery, the idle was very low. So I cleaned out the idle air port and valve. Then it was high. I drove it around for a few days like that and then started replacing stuff, to no avail--still high. I also cleaned around the throttle plate.
Dakota :: 2000 4.7L V8 Overheating In Idle / On Highway At High Speeds And While Driving Slow
I drive a 2000 Dodge Dakota Sport w/ 4.7L V8 engine. I have been dealing with an overheating problem for about 6 months now and have nearly exhausted all hope of correcting the issue. It has been in the shop on 4 separate occasions and seen 2 different mechanics. The radiator has been replaced, the thermostat and thermostat housing have been replaced, the radiator fan works properly, hoses have been replaced and no subsequent leak has been found by either mechanic, they haven't mentioned the possibility of a blown Head Gasket (nor has the typical "milky residue," shown up in my oil cap). Each time I got it back from the shop the problem was fixed for about two weeks, then returned and slowly got worse.
It overheats in idle (with the fan running), on the highway at high speeds, and while driving slow. Sometimes it only gets about 3/4th to the red (usually when its cool at night) and sometimes it will hover just below the red; while I'm doing everything I can to keep it from hitting red (defrost on, revving engine). Some days it takes a little while to get hot and some days it happens very quickly. I'm tired of sinking money into the vehicle but as a recent grad I don't have the money for a new truck at this point. Suggestions included heater core clogged, water pump gone bad, fan clutch.
