Ford F-150 - 1997-2003 :: 2001 - Running Rough When Cold / Stalling Out When Coming To A Stop Light
2 questions regarding our 2001 F150 Supercrew. My 2 questions are:
My 2001 Ford F150 Supercrew (5.4L, 230,000 miles)has the check engine light on with the code reader telling me that it is the P0174. The truck would run rough when cold (usually in the mornings) and sometimes it would get close to stalling out when coming to a stop light. So we would quickly put it in park and give it some gas to rev it up a bit. After the truck gets warmed up, it runs great with no hint of the rough idle. Since this all started I have changed out the PCV valve and replaced the PCV hose (including the elbow). I have also replaced the Idle Air Control unit but that didn't really make a difference.
We then experienced a cylinder #4 misfire which we resolved by changing out the cop with a new Motorcraft unit. The misfire went away but we still had the problem of running rough at idle to the point of stalling out at stops when the engine is cold. A few weeks ago we cleaned the MAF sensor and that seemed to work. The truck doesn't run as rough now (when cold) at stop-lights, but occasionally it will still have the loping idle. We cleared the check engine code and it stayed off for about a week before returning.
I don't know what else to check other than trying to see if there is some type of vacuum leak, but I don't have access to a smoke machine nor would I know how or where to hook one up. Removing and cleaning the throttle body would work? What could be causing the trouble, or what I should do to further isolate or troubleshoot the problem? I saw a you-tube video on the F150 intake manifold gasket possibly being the problem and although I hope that isn't the trouble with my truck, if it is then I will have to deal with it. We need the truck to get to work and the car is now due for a registration renewal, but we can't get a California smog certificate with the check engine light on.
Malibu :: Running Rough At Stop Lights - Check Engine Light Came On
I recently replaced the head gaskets in my 2003 Malibu. First time and all seems other than it runs rough at stop lights. The check engine came back on and so I had it read and there is an air flow issue. Is there anywhere that I can get a schematic for the vacum lines? I have all over and cannot seem to find a loose or broken one.
View 3 RepliesChevrolet :: Engine Is Running Kind Of Rough And Has Tapping Or Knocking Sound
It is a 2002 or 2003 Chevy truck with a diesel engine. He was going down the road the other day under normal driving conditions when the motor made a racket and then white smoke started coming out of the back like a chimney. The truck will still crank and run (and smoke), and now there is a knocking or tapping noise that is coming from the engine. The engine is running kind of rough, and has the tapping or knocking sound, but it will calm down for 1/2 a second at which time the rough idle and noise stop, but quickly return. There is no engine code showing, so my code reader is useless. I once had a Chevy 350 with a spun main bearing that sounds similar, but the motor didn't idle rough or smoke. I don't know enough about diesel engines. I was told there was a possibility of a bad injector pump or bad injector itself. Is there any way of testing this yourself, or does it require a shop trip?

Our R32 has 2428 miles- and today the check engine light came on and it started to run pretty rough, babied it home and the the light was blinking when I turned into the driveway.. I know that booklet 3.2 in the owners manual is diagnosing catalytic converter issues...I have always used super unleaded, it hasn't even reached the halfway point of the first service.

I wanted to pass along the results of a brake issue I encountered in my 2010 Prius (15K miles) and report to interested Prius owners how the issue was resolved.
Problem: In the last second (or so) coming to a complete stop I noticed a few light clunk type sounds, like something was loose up front. I never experienced any degradation in the braking performance.
Golf VI R :: Engine Sounds Coarse Or Rough During Warmup?
Golf R, 3000 miles. Seems like the engine sounds coarse or rough between 2-3k rpm for the first 5 minutes or so of operation. Smooths out after it is up to temp. Does not run rough, it's just an audible thing. Relatively insensitive to outside ambient temperature (winter/summer). One oil change with Motul Specific, Soundaktor still in place. Is this typical or am I the only one?

View 8 RepliesGolf IV / Jetta IV :: Clicking Sounds Coming From The Engine Bay
The issue I'm having, as stated is a no start issue. Its completely random and has no pattern. Here is the issue.
When the issue occurs, you will go to start the car to only have it click at you. No crank, no nothing. The click sounds like it comes from the engine bay but has not been confirmed. If you turn the key without the clutch in, putting the clutch in will make the click sound.
Thinking it was the ignition switch, I replaced it with a unit from advance auto. The issue occurred again shortly after so I pulled it out and put the old one back in. Then I replaced the starter. That didn't do it either.
It hasn't done it in a while so I kind of forgot about it but its started doing it again. Time to fix it.

Prius (Gen 2) :: 2006 - Knocking And Rattling Sounds Coming From Left Tire
I currently own a 2006 prius which has done about 100k km. I've been hearing knocking and rattling sounds coming from the left tire whenever I go over a rough patch of road or even a speed bump, between slow to moderate speeds. It's currently bearable, but it gets irritating at times and it seems to be getting louder. What is the cause of these noise and how I can rectify it? I wish to get rid of it.

My mechanic tells me I need the intake manifold gasket replaced (check engine light on, engine surging, running very rough). How much damage can I do to the car by doing this repair myself and screwing it up? I've done lots of repairs on my car before -- brake pads, rotors, replace oil pan. I also have a copy of the manufacturer's shop manual.
View 2 RepliesPassat (B5) :: Car Running Rough And Engine Light Came On
So- I take the variant in for a 65000 mi service- i.e oil change- and to get the recall done on the crankcase hose. I pick it up, drive out, and at first stop sign --- it starts running rough and engine light comes on. Take it back- they throw the computer on it and it throws a code for vacuum leak connected to brakes.. they take it back-pick up next day---they had to replace the brake booster (under warranty, extended-nice of em, I guess), because, they say, the cowling plug was plugged and water filled the booster. I HAD smelled musty water smell. But- why did it just go in the shop?? 60 bucks to unclog drain- W.
View 3 RepliesGolf IV / Jetta IV :: ASR Light Came On / Running Rough And Smoking With Codes
I was driving along the highway cruising at around 100 km/h when out of nowhere the car started driving a little rough so I look down and the ASR (traction control) light was on. I got off the highway, shut it down and fired it back up. The ASR light was off and car running like normal. When I got home I scanned it and these codes came up:
The catalyst code if from my catless turbo-back exhaust which I plan to fix next month with a tune. Anyway I cleared all codes and continued on my way without any other hiccups. So is my MAF sensor dying/dirty? ECU? N75 valve? Boost leak? I'm making a boost leak tester today just to 100% eliminate that variable, though I'm fairly certain I'm good there.
The car is mostly stock except for a few bolt-ons, all of which I've had installed for thousands of kilometers now. Here is what isn't stock, not including suspension, wheels, etc:
Forge 008 diverter valve
034 Motorsports PVC silicone hose kit
Samco boost hose kit
Forge silicone turbo inlet pipe
Eurojet SMIC
custom built 2.5 stainless, catless turbo back
AEM Dryflo short ram intake
GLI MFA cluster
Accord :: 93 EX-R Running Rough And Engine Light On - 3rd Cylinder Not Firing
I started the car the other day and it was running really rough and engine light was on. I started pulling the spark plug wires and pulling #3 didn't make any difference in terms of decreasing performance where the others all did.
I've replaced the plug, and distributor cap. I've also confirmed with the plug out of the block that it is firing.
I'm not sure at this point what to look at next. This happened overnight, not gradually over time, and apart from running rough the engine isn't making any noises which based on sound, and how fast it happened doesn't make me think its a scoring/compression issue.
Touareg :: Running Rough At Idle Then Check Engine Light Comes On
Filled tank with 8 gallons of 91 octane to top off. One hour later noticed car running rough at idle then check engine light comes on. Could it be the coil pack? Car has been running very well until now, and this Gremlin appears. I don't think it's the gas.

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.

View 1 RepliesTouareg :: 2004 VW - Check Engine Light Is On / Running Rough At Low RPMs
I have a 2004 VW Touareg with 116K miles. Yesterday the check engine light came on and she is running very rough at low RPMs. The manual tells me that there is either a problem with the exahust manifold or an O2 sensor is bad. It feels as if she is struggling for air. When you start the vehicle the check engine light flashes then stays on in the cluster. What can I expect when I take it in to the dealership? Is there anything I can check before I take it in?
View 4 RepliesPassat (B5) :: 2003 - Check Engine Light Came On And Car Is Running Really Rough At Stops
I have an 03 Passat with about 70K miles on it. My daughter put rug in it this morning (about 7 gallons) and since then the check engine light came on and the car is running really rough at stops. While accelerating, it seems to be fine. It is also getting about 10 mpg less than normal. MIL codes: P0300, P0301, P0302, P0303, P0304, and P0171. He said the P03xx codes were related to misfirings on each cylinder. The P0171 is a bank 1 failure (?). What do those codes really mean and could they be related to bad gas? Sent her off in my TDI JSW so she's not out on the highway if the Passat decides it doesn't want to go anymore.
