Subaru - SVX :: Rough Idle / RPMs Drop Very Low And Engine Shuts Off
1997 Subaru SVX (Alcyone) LSi, 3.3L H6 engine.
My SVX was driven from Denver to Las Vegas, NV and it developed an odd habit where the RPMs would start to oscillate while on cruise control. I had to disengage the cruise control to get the oscillations to stop. Three days later I was driving the SVX to work and the RPMs started oscillating at idle and the car started running rough and it died.
These things have all been replaced with OEM grade parts: Spark plugs, electric fuel pump & strainer & fuel filter, Mass Air Flow sensor, new air filter and fuses.
The car starts up fine but after a few seconds the RPMs begin to oscillate. Then the car tries to recover, the idle becomes rough, and the the RPMs drop very low and the engine shuts off.
1992 S10 Blazer - Rough Idle At Start / Shuts Off In Gear And Engine Never Getting Higher Than 180
1992 S10 Blazer, 4.3L, 4x4, TBI "Z"
When I start the truck, it idles rough, like it's idling too low, and even feels like it's missing during idle. Sometimes when I put it in gear (reverse or drive), it shuts off. No codes are being thrown. It has no problems driving around town or on the highway. It's just that initial start and idle.
I've checked all the following with a shop manual:
Ignition Control Mod.- Orig and 2nd one from junk yard. Both tested good at store. Even the testing in the shop manual with an ohm meter and battery tested good.
Ignition coil- tested good using shop manual testing
TPS- Scan shows .2-.7 at idle.
Plugs, wires, cap, and rotor are good.
Vacuum is good.
Haven't checked IAC, EGR
I recently moved cross country, and about halfway through, I broke down. Engine would turn over, fuel relay would click, injectors would work, but no fuel. Pulled it in to a truck shop, and after all my testing and theirs, we determined it was the fuel pump. After they had to fix a pinched hose, it ran. I made it to Texas. I didn't have the idle issues prior to the trip. Just had the tranny rebuilt and everything was great.
I thought, at first, the ignition control mod was the problem because it got a bit warm pulling the trailer, and I know those things don't like too much heat. No dice. So, what controls idle at Park and in gear but at idle? EGR, IAC?
I did a WinALDL scan. IAC at Park/Idle ranges from 18-55. The engine never runs in Open Loop. I would say the engine runs mostly rich according to the scan. I've attached a manageable version of the WinALDL data.
Also, I need to check the thermostat or temp sensor. Scan reads the engine never getting higher than 180.
Santa FE SM (2001-06) :: Hard To Start After Fill Up - Rough Idle And Engine Shuts Off
Every time i stop for gas..my 01 santa fe is hard to start..it would take 4 to 5 start before she goes, then i have to keep the rpm up, bring her to idle..after that shes ok, till the next fill up.. the only way around this is to keep her running while gassing up..while filling up she run rough idle, some time engine shuts off..then its hard to start..
View 5 RepliesGolf IV / Jetta IV :: Car Idle For About A Half Hour And Shuts Off
I have narrowed down my starting issue to a faulty relay(409). When I pulled the relay and cleaned the contacts and reinstalled the pump primed and the car started. Car will idle for about a 1/2 hour and out of the blue it shuts off. If I try to restart, 9 times out of 10 it does not start. If i tap the relay, it starts right up. If the car is running and I tap on the relay the car stutters and if I tap it again it shuts off.
View 10 RepliesGolf V R32 :: Car Shuts Off - When Restart RPMs Bouncing At Idle
I got a mkv R32 with 57k miles (DSG transmission) on it and the past few weeks ive been having some crazy issues. My car shuts off once in awhile when I come to a stop in traffic or at red lights. Last night it happen again I came to a red light and the car shut off, when I restarted it my idle was bouncing all over the place all the way up to 2500rpm and down to 1300rpm. Also, in addition to the idle every time i started pressing the gas the car would KICK like something was wrong with the transmission and a CEL came on. I ran the codes and it said MAF was at fault and I have had a MAF code again maybe a month ago.
I am thinking of replacing the MAF to see if it fixes the problem and I was wondering if it is a straight hardware swap or will i need to do some programming with a vag com?
Scion - Tc :: Shaking / Idle Drops - Car Shuts Off When Idle On D Or Reverse
I drive a 2006 Scion tC with 96000 mileage. The car has been getting a lot of problems lately.
1. P0741 torque converter engine light
2. Lost in power
3. Lost in MPG
4. Shakes a lot inside
5. Low Idle
6. engine shuts off on reverse and d mode
7. Noisy strange sounds
8. Gear slip around 2-3
9. RPM goes high at low speed.
I Replaced,Spark plugs, coil plugs, engine oil, coolant, steering fluid, brake fluid. I need to to replace the transmission fluid. I was told by a couple of shops to get a transmission rebuild....
I also read someones comment online: "It's your transmission. Your torque converter is bad. There is too much torque as a result. When your car is in neutral or park there is no torque being created. When you leave the in gear idle state, the torque is relieved. That is why the problem will go away when you hit the gas."
Golf/GTI VI :: TDI Has Rough Idle
Once in a while, I notice that my TDI has a rough idle. It feels more like a shake in the seat than rough idle. But I don't know how else to describe it. This usually happens at warm up- after driving about 5-10 minutes.

I've been having this problem lately, when its a hot day the car revs up passing the 1000rpm's or when I am in traffic for a long period of time it does the same and its stays there for a while ( like 5 mins) then returns back to normal. Heres a video so you can see of what I am talking about... [URL] .....
View 10 RepliesGolf IV R32 :: Bump Start / Very Rough Idle And CEL On
So last night my battery died, and nobody around me had jumper cables.....so I was forced to bump start the car
It worked, but now the idle is really rough. At a stop in neutral the revs stay between 800-1800 sometimes. When I'm up shifting, every time I left off the clutch the revs jump about 200 rpm and now I have a CEL.
What could have happened?
Golf IV R32 :: Rough Idle And Warning Light?
My R is acting up a bit today. I went to start it this morning and the battery was dead. I'm not sure if I left the stereo on (it doesn't turn off when the key is removed and door opened. I have to disconnect the faceplate every time.) or what but it had just enough juice to unlock the doors and light up the some light LEDs. After I got home from work I went to jump it and it wouldn't even unlock. I had to use the key to manually unlock the door.
I was able to jump it just fine and took it for a drive. It idled high sometimes and would drop down to roughly 400-600 RPM. Driving the car, it was clearly lacking power and not running properly and the traction control light came on. I parked it in the driveway and took a video of the idle, shut the car off and started it up again. This time, the idle seems normal but it doesn't feel as responsive or powerful as it was before today. The traction control light is still on as well. If I rev the engine up, it'll drop down to around 1,100-1,200 rpm, sit for a few seconds then finally drop to 800.
I just got it about three weeks ago and haven't done anything to the car. Hopefully this is something minor because I don't really feel like dropping a ton more money on a car I just bought.
Golf/GTI VI :: APR Stage 1 - Car Revving On Its Own And Rough Idle
So today I went for a drive in my mkvi gti with apr stage 1 and an intake and the car was idling rough and then as i pressed the clutch to take it out of gear and brake the car would rev up to about 3k and drop ant go up and down a couple times until it returned to normal idle and still it would idle rough and this happens every time i press the clutch to take the car out of gear. also on a cold start it would jump up to like 3k and then slowly drop down.

So this morning when I went to start my car for work, it wouldn't idle and was misfiring badly, also has a very loud noise coming from the valve cover. The car has under 40k miles on it and is CPO, so it'll be towing it to the dealership today to get check out. The car ran fine on friday when i parked it.
Here is a vagcom scan I did this morning also.

Golf IV / Jetta IV :: Rough Idle Between 600 - 800 RPMs
My golf 2.0 vw isn't doing so good right now. It has 227000 miles on it. It has been driving great, and then last week it started to idle rough. It idles between 600-800 rpms. it fluctuates between 600-800 rpms. It had the check engine light on before this happened i was told by my brother that it was an 02 sensor. I had it checked for what is causing the engine light to come on today at o Rileys, and it came up with 11 codes. Some of the codes where 02 sensors, it was running to rich, needed a new computer, evaps system, fuel pump, fuses, coil pack, spark plugs, It shakes when you sit in it when it is idling like not a bad shake but a small one you cal feel, l'm including a video of it running.
View 6 RepliesGolf V R32 :: Rough Idle After Cold Startup
If my car's been sitting - say monday morning after sitting all weekend in the garage- it runs rough for a little while. Sometimes only for a few seconds, sometimes for a little while after the idle drops. The colder the car is, the longer and worse the condition. It feels like a cylinder isn't firing.
After a particularly cold and wet spell (I had the car outside) it ran so badly it threw a code for one of the cam position sensors and #4 misfire. I replaced both of the sensors. That worked a little.
Since I was due for 80k service and saw a misfire when damp, I replaced the ignition coils along with the spark plugs. That worked a little more. But, it still does it. What else could it be if not ignition? Sticky valve? something else?
Golf V R32 :: Rough Idle After Engine Rebuild
Just yesterday cranked my car for the first time after complete engine rebuild!! Before starting I cranked it couple of time with the spark plugs out and fuel injection still on. This was to get the oil/fuel pressure up.
After that torqued everything in place and it jumped to life instantly. The car runs really smoothly. No clicks or ticks and all the timing chain noise in gone for good. I warmed the engine with 1500-2000rpm and checked for leaks.
Only minor one was in the oil filter housing, couple of drops came between the cooler and the housing. (this was oil)
Fans, thermostat and basically the whole cooling system worked good. Lifted the reservoir up to get the air out, worked just good.
Mate was inside the car to look the revs and checking the stats in VAG-COM.
But... It was really hard to keep the revs between 1500-2000rpm and with a slight touch of the gas pedal it you could adjust it but it wanted to go over the needed all the time. When you lift the pedal just a little the rpm sank pretty fast.
When you take the foot of the pedal completely the idle RPM drops to 600-640 according to VAG-COM
What could cause this?
-vacuum issue?
-does not having brakes installed affect this?
All is torqued by the Bentley manual. I still have the steering rack and the brakes uninstalled (calipers off)

A few days ago I noticed a very rough idle first start of the day, this happened twice, then on my way to a show this morning, I lost most power for about 15 miles, boost would not go above 0hg, all the sudden on the highway,BOOM, back to normal...during all of this no engine light or CELS were displayed. Scanned the car later in the day and the only thing that showed up were some random fueling errors, cleaned the codes from the memory and so far so good all is fine!
View 18 RepliesGolf IV / Jetta IV :: Assuming Car Clogged Because Of Rough Idle
After putting on a o2 spacer my CEL cleared. I finally got some downtime so I parked the car in the garage to chase electrical gremlins, do the timing belt, and replace the downpipe and catalytic converter. Lately it's been sounding like I have quite the exhaust leak so that spurred me into doing a little quicker. Long story short I got the cat out and after looking inside of it I see this .
The inside of the cat is completely bare, not even a remnant of any form of honeycomb. So was this a hollowed out cat or did everything deteriorate and blowout. I was assuming my cat was clogged because of my rough idle lately... but looks like I was dead wrong.
Now for additional info.

Previously had a CEL for the catylst below threshold
I can't currently check my codes because the OBD2 isn't reading/connecting, but that's not related.
