View 2 RepliesTwo mechanics have told me that I need the valve cover gasket in my car replaced. I have all of the classic signs of needing one--the smoke coming from under the hood, the drops of oil on the pavement after the car is parked for a few minutes, etc. The problem is that I won't have the money until around Memorial Day. I drive about 300 miles a week. How desperate a repair is this, and what are the signs that I need to have it fixed immediately?
View 5 RepliesI have a 2003 Mitsubishi Diamante that I have owned since 2008 purchased it with 60,000 miles on it. Currently has 131,000 miles. I have always kept my car in good running condition and performed all of the scheduled maintenance per the owners manual. Last month I noticed a slight cold knock on the right side of the engine that would go away when the engine warmed up. I checked the oil and noticed that it was a little bit low (maybe half a cm below the lower threshold on the dip stick). I added oil and continued to drive it, still knocking.
Bought some sea foam thinking it was the lifters and sprayed a can in the intake and poured some in the oil. Then changed oil with 5w-30 synthetic, have been driving it for about 500 miles now and the cold knock seems to be getting worse and I can faintly smell burning oil when it is idling as I let it warm up before driving off. By the time I get to work the knock is essentially gone. My oil levels have been fine... My question is, should I be explaining to my wife and fiscally responsible self, that I need to be looking for a new (read used) truck sooner than I had initially planned? Or, is this something that can/should be addressed or just drive it until it gives out...
My car makes a ticking noise as soon as I turn the key to the 'on' position. The ticking continues once the engine begins running and stops shortly afterward (maybe 10 - 15 seconds). I'll attach a video of the ticking after the car is already running. I've checked the service light. It is the catalytic converter. I'm pretty sure this is a separate problem, but am not sure what is causing it.
View 3 RepliesI have a 2002 Mitsubishi Diamante LS. I know I know, but I am a poor student (emphasizing poor), and this car is paid off. Anyway, A couple months ago I drove through a puddle, water splashed up into the engine area and my car died. I was able to start it an hour later (after it dried out, I guess) Since then, there have been a couple times that it wouldn't start right away, it took a good 20 minutes for the car to start after the initial try, both of these times have been after a heavy rain. And now, occasionally, I smell a slight electric burning odor. I replaced the battery after the "driving through the puddle" incident. I just hit 80,000 miles. Obviously there is one or more issues I need to deal with.

View 1 RepliesI have a 1995 Buick Century with 149,000 miles that will occasional and randomly idle rough when started warm. Also, on several occasions it will idle so rough it kills the engine and I'm unable to start the engine until the thermostat reads completely cold. I've taken it to 2 separate mechanics who both are unable to pull any error codes (even after the engine has died) and are unable to duplicate the problem. When it does idle rough most of the time I can rev the engine, put it in gear and drive it for a few minutes and the problem disappears. Other times I try to put it into gear and it kills, I put it into park and try to restart the engine and the engine will start for a brief second and then die and will die faster each time I restart until the engine doesn't turn over at all. Then once the thermostat reaches 'C' it starts up like there was no problem at all.
Here is a list of recent pertinent repairs:
- Replaced Battery 12/2/11
- Replaced plugs and wires 4/11/12
- Throttle Body Gasket and Fuel Filter Replaced 3/18/13
- PCV Hose replaced 2/19/14 (last mechanic's guess on the problem)
I don't notice any signs of a rich fuel mixture or abnormal exhaust (there was a discussion with a Buick with no start that had this).
I have a 1995 Nissan Altima GXE 4cyl and it has been rough idling for a while now but now I have this new problem. While I drive the car and after it has warmed up, the car shuts off when I'm at a stop. When I'm at speed, it runs just fine and smooth and I only have problems at stops. I then restart the car just fine and continue driving. I'm having to keep doing this over and over. What could be the cause or causes for this?
View 4 RepliesSo I have a 95 aerostar 3.0. I use it every day my a delivery vehicle. I keep it maintained. About a month that ago, it developed a skip or a hesitation, most!y at high speeds, usually under load. I thought it may be transmission but had it checked and was ok. I drove it like that for several weeks. Then got worse so I parked it for ten days until my mechanic was available. When I cranked it to drive it over, it spit and sputtered the whole way here and barely made it. It had never done that before. He changed plugs and wires and distributor cap, even though it had been less than a year since all that had been done. Still no change. Driving way worse after sitting for ten days.
View 6 RepliesWe have a Galant with approximately 76,000 miles. Lately, we have noticed that when it rains the car sputters and accelerates really slowly up to 30 mph. Once we get to 30, it acts normal. Sometimes if we turn the car off and then start it again, this problem goes away. My guess is it is something with the computer.
View 2 RepliesI have a 1995 ford thunderbird 3.8 l. I changed the heads according to a chilton book. The car ran well for approximately 2 weeks and all of a sudden it started Idling high. I turned the idle screw all the way off and no change.

View 17 RepliesThe problem I have is when it is cold out under 40 degrees, my car starts rough and idles rough until it gets to temperature. My research has concluded it may be cold start. Does this sound right?

View 8 RepliesI have a 97 grandam 3.1 The engine idles rough but runs fine when you give it the gas. It shows no codes.
View 6 RepliesWell, a couple months ago my engine started making a noise. We located the issue to be a loose timing belt. We had it tightened, and the noise stopped, but since then it kind of acted like it was a little out of time with rough idles every now and then. This past week, I had driven my car out. I came to a 4-way stop and the car shut off on me. It would not immediately start back up so I pushed it to the side and waited a bit. It started up after sitting for a few minutes and cooling down. I got it back home and it stalled right as I was turning into my driveway (after the RPMs had lowered to idle).
A couple of days ago I set out to replace the timing belt as it seemed to me the timing was off ever since we tightened the belt and it eventually got worse, thus the stalling. I changed the timing belt, set the timing on the cams the way it shows to be set below:
I set the timing on the crankshaft pulley to the specifications found in this video:
Which is putting the crankshaft pulley on and turning it until it aligns with the '0' mark on the bottom timing cover. So I decide to start the car without anything else on to make sure its in time. It fires right up so I shut it off quickly and go about putting it all back together.
Once the car is completed, I attempt to start it again. It fires up, I back it up and it dies. It would not start back. I waited a few minutes and attempted to start it again, it started up so I pulled it back up to the same spot it was in and shut it off. Took the pieces off again, got it back to where I could line the timing up again. I again set the timing one more time to make sure. It was set correctly. I then tried starting the car again and this time it would not crank.
I gave up for now as its 30 degrees outside and I have been working on it non stop for 3 days to no avail.
02 Passat 4Motion with the 3.0L V6. I just had the car at the dealer 2 weeks ago for the 50K service and to have the temperature gauge fixed. Otherwise, the car was running just fine. At the service, they replaced the water temp sensor, performed a fuel injector service and radiator flush (both recommended).
Now two weeks later, her car rough idles, dies and has to be towed to the same dealership. They first diagnose fouled plugs which they replace gratis. They then tell me the plugs fouled because the ignition coil and wires have gone bad and need to be replaced. They want to do an additional injector/intake cleaning service. They are offering to discount the services slightly. I'm still going to be out another $850.
I called Volkswagen Customer Service and they confirmed that the ignition coils were not covered under the recall.
Something sounds "off" to me. The car was running fine before the initial service. Was the dealer just being "nice" in comparing the plug replacement or did he think that they initial fuel injector service may have fouled the plugs? I don't really want to pay 2x for the same service and now the coil/wire replacement.
I have a 2003 2.0 gas Jetta (181k miles, automatic.) that won't rev over 3k, starts rough, idles rough and wont stop setting a P0341 cam position sensor code.
The car was not running when i got it, i replaced the coil pack and it ran but not over 3k. Cleared codes, it sets the P0341 immediately.
Had timing belt, water pump, tensioner and cam pos sensor replaced. Still, sets p0341 code, starts rough, idles rough and wont rev over 3k.
The throttle servo makes a little noise when actuated, shop thinks this is my demon - suggests replace throttle body.
I just had my timing belt, water pump, etc. replaced at a reputable indie VW shop. I just got the car back and it seems to idle a bit rough. The car used to purr like a kitten but now it shakes a bit in idle. Seems to run fine but the idle is rough. I'm going to bring it back to the shop on Monday. Can the timing be off a bit? Will it ever purr like a kitten again?
