Golf IV / Jetta IV :: Idle At 1200 RPM Way Down To 800 When Starting And Engine Is Cold

I have a 1.8t jetta that has a weird idle issue when starting and engine is cold it like to idle at 1200 rpm then will eventually work its way down to 800 rpm

I have no cel codes and have looked for vacuum leaks (but may have missed one) ,but if i start the car and it idles at 1200 rpm then i shut it down and start it right after it will idle at 800 rpm as normal.

Its a 1.8t unitronic stage 1 stock everything except e type coils with plugs at .032, Also does not have much pull after 4000 rpm, not to worried but just may be part of the issue....

Golf 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?

Ford Escape / Hybrid :: 2001 Won't Idle After Starting - Cold Engine Misfire

I'm needing cold engine misfire. 2001 escape 3.0 engine 190300 miles on it. I changed the plugs, cleaned the fuel injectors, new air filter, new fuel filter, cleaned the pcv valve and new ideal control valve. When the engine is cold it starts right up but wont idle right and misfires sputters some to but run the rpm's up and it smooths out. drop to idle and it misses. Now when the engine gets to operating temp it seems to run fine. What am I overlooking to find the problem?

Camry :: 1995 V6 - Rough Idle / Engine Lope When Started Cold

We have owned a 95 Camry V6 for 20 years and it has always been reliable. However, several days ago, the car started to have its first engine performance issue. When we start the engine cold, there was rough idle/engine lope. If it was warmed up for about 5-10 minutes, the car was fine for the entire day. but during this rough idle, the car jerked slightly as well if i press on the gas.

Since the symptom began, I took it to local shop A and they replaced all the spark plugs, pcv valve and air filter which did not solve the rough idle/looping problem. The rough idle continued, and few days later, I was unable to start the engine though it cranks. (at least that's what I think it does). Had it towed to shop B and they've replaced oil pump, which they thought to be the problem. I took it home, and the next morning I found myself unable to start the car.

Ford 6.0L Power Stroke Diesel :: 2006 F250 - Rough Start And Idle When Engine Cold

Truck has been doing this and now getting worse. 06 f250 6.0 147,000 miles. Runs like crap when you first start and truck has trouble shifting when I first take off in the mornings until it warms up then it idles fine and runs like a champ no problem shifting. Not in a cold climate 40F at the least. Not trying to take it to the dealer and get raped. Been doing research some people say get the inductive heat flash, some say needs new injectors, some say could have a bad gasket on the injector idk. I'm trying trying to get it resolved....

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)

Golf/GTI VI :: 2009 GLI - Running Rough / Engine Seems To Chug A Little When It Was Cold

About a week ago I purchased a new K&N air filter for my '09 GLI (6spd stick & all factory options with 55,000k on the odometer). Outwardly the vehicle seemed to run better (although a new clean air filter of any type will make a vehicle run better) however, 2 days later I noticed that the engine seems to chug a little when it was cold. Not missing like a plug wire off but a chug where it surges forward then holds back continually until the engine warms up. This persists today. I've also noticed a little bit of a rough idle. I've re-inspected my installation and nothing seems to have come loose and the filter fits perfectly.

Intrigue :: GLS Hard Starting / Rough Idle

My wife's Intrigue has had a hard starting/rough idle/rough start issue for a little bit now. On a hunch this weekend I decided to clean out her throttle body. Turns out it was more full of soot than a chimney in February. Nasty black carbon buildup. Took a toothbrush and some throttle body cleaner and scrubbed it out best I could. Car runs great now, very smooth and responsive. Gas pedal use to stick, even fixed that. So I'm a hero, until we realize that her car is still starting hard. Turn the key and the engine turns over no problem, starter sounds good. Once the engine is running it purrs like a kitten. But sometimes you have to crank it for several seconds before it fires up.

Golf IV / Jetta IV :: 2004 - Rough Idle / Bucking When Engine Is Warmed

I have a 2004 gls 1.8t Jetta. It has a straight piped turbo back exhaust, and a stage 2 tune. I recently had a problem with my car starting to rough idle when the engine gets to proper temp. The car starts to idle roughly, and when driving the car will bog down, if I keep my foot on the gas, the car acts like it is coasting and the rpms fall, but at some point the car will shoot off like i floored it. At lower rpms in the 1st and second gear, the car will randomly and periodically start bucking, with the same symptoms. I already replaced my coil packs and spark plugs with a kit off ecs, and when i went to change the spark plugs i had oil on the spark plugs and oil leaking from a bad valve cover gasket, so that was replaced as well. I replaced the fuel filter already.

The MAF sensor was just cleaned and didn't look too dirty. When I unplug the MAF it still idles rough. The fuel pump relay can be heard working properly when the door opens. Another problem that sometimes occurs on cold start is if I don't wait long enough for the pump to activate or sometime right after it starts, the car will start partly then stall out. When driving and the car is bucking the exhaust gives rich fuel smell. Also when 2 stepping in the car (which I don't do very often), the CEL starts to blink and the car misfires and drives rough. I figure since I don't have many parts on it yet I probably shouldn't do it anyway so I don't blow up the engine.

Golf IV / Jetta IV :: 2000 - Rough Idle - Flashing Check Engine?

The check engine light came on in my 2000 Jetta and the engine power suddenly decreased noticeably. Got worse quickly and was idling rough, like it was about to stall out (but didn't). Took it to dealership, they said spark plugs were the problem and replaced. All seemed normal driving home, but after 10 minutes, same problem: check engine flashing, weak engine (trouble on hills), and a rough idle.

Two questions: what could it be?

and is it safe to drive back to dealership (~10 miles) or might that cause further damage?

Golf/GTI VI :: Extremely Rough Idle And Engine Stall With Clutch Depressed

This morning when I started my car the RPMs were all over the place. The engine would rev to just below 2k and then drop, as it it were gonna die and right before it did, it would rev back up. Then, when I tried to move it, it would not accelerate and would hardly move and while coasting it dies if the clutch is depressed. The car does not die when idling (albeit a very rough idle) but it does when it is moving.

It flashed a check engine for a few seconds at one point but went away and has not come back on. I am running APR Stg 1 and a Carbonio intake. I switched from 93 octane mode to stock and nothing changed.

Golf/GTI VI :: 2013 - Intermittent Rough Idle / Shakes As About To Stall Out - Engine Light On

I have a 2013 Golf TDI with 2070 miles on it. For around 2-3 weeks, I've noticed that it intermittently will idle rough, shakes, etc, as if it is about to stall out, but stays running and drives normal. I figured it was a typical Diesel thing and wasn't too worried about it. However, today, this happened, and I got an engine light. Yikes! I made an appointment for it but need to wait till after the 4th for it to be looked at. What's up here? Is it a regen cycle? Timing issues? Am I doomed with my Golf TDI?

Golf/GTI VI :: 2010 - Engine Shake / Vibration At Idle And Cold Start

I've had my 2010 GTI for 8 months now and have really only had one issue with it. When I start the car, it shakes before I start moving. Like, the steering wheel, body, pedals, gearshift, etc... It's not a violent shake, but definitely something I've never noticed in any other car I've owned including my MkV GTI. It doesn't seem like a normal feeling for a brand new car. I took it back to my original dealer at 4,000 miles and they said there was nothing wrong with it and they didn't feel any vibrations.

Well lately it's been vibrating more intensely and more often (at almost 8,000 miles) It now does the same thing while stopped in traffic or at lights. It's really annoying to me. I took it a couple days ago to a new dealer (I moved) and just talked to them on the phone. They also said there's nothing wrong with it and it's normal.

I forget exactly what they said it was because I was walking to the gym, but basically it was some cooling pump/fan that kicks on to cool the engine down and that's what is causing the vibration. But, they said it's normal and all VWs do it. I'm not quite sure why a fan needs to cool a perfectly cold engine in the morning though.

Ford - Explorer :: Stop If Don't Step On Gas After Starting - Rough Idle

1994 Ford Explorer; When I start it, if I don't step on the gas it will stop. If I give it some gas when I start it, the engine will race and then decelerates about 2000 rpms and keeps doing this, it does get better as the engine warms up. But the idle is really rough. It has new wires, plugs, vacume lines, oil change, air filter and battery. If I put the gas pedal to the rug, it will go from 4000rpm back down to 2000rpm and continue doing this as long as I keep the pedal to the metal. I had it put on an analyzer and it didn't read anything.

Buick - Century :: No Start When Damp Or Rough Idle After Starting

When damp or foggy, my 1990 Buick Century 3.3 will either not start or start and idle rough. Spraying WD-40 on coil packs and wires work. I tried click and clack's method of misting water on the 3 coil packs and wires when idling, and got arching on middle coil, # 2 wire to top of coil pack. Do I need to replace that coil, or just the spark plug wires? The slight mist of water on that middle coil stalled the engine, and it would restart after WD- 40 was sprayed on the coils/ wires.

Touareg :: 2006 - Runs Rough After Cold Winter Starting / Choke Stuck Closed

I have had my 06 for 4 months now. I started to get a cold running problem now that the temperature is falling below 40. When I start it in the morning I wait till the idle comes down before driving. I start driving and it runs rough as if it had a choke stuck closed. I spoke with the dealer and he told me to run lower octane in the winter. That has not worked.
