I have a a 02 jetta 1.8 turbo the code po343 came up after new temp sensor,valve cover gasket and full tune up. is it an easy fix the car is misfiring an very hard starting.
View 1 RepliesI did a valve cover gasket replacement. Changed all spark plugs and coilpacks. The car is still misfiring. I also just did the timing belt and water pump. Why it's still misfiring?? I'm new to this whole forum thing so bear with me lol. I'm wondering if it would be my cat, fuel pump, fuel filter. Or could it be a sensor?
View 2 RepliesI'm thinking of purchasing a 2001 GLX VR6 Jetta with lots of deferred maintenance (shocks/struts, brakes, exhaust). Most worryingly, the valve cover gasket is leaking oil. The price is pretty low, but is such a beast worthwhile at any price or is it better parted out? And the interior is about as beat up as the mechanical--screeching passenger window motor, broken glove compartment ... Is this thing worth being brought back to life?
View 6 RepliesMy mk4 sat for a while and upon starting up was misfiring. I checked for pvc leaks and didn't see anything but went ahead and cleaned my maf sensor and decided to pull my coils. Cylinder 1 had oil on the tip and around the spark plug which to me spelled out a bad valve cover gasket. I got all the parts to do the inner and outer gaskets and replace the coil and spark plug, however we got a snowstorm and my luck a rabbit got in and ate the wiring on one of my fuel injector connectors.
So went ahead and put on the new gasket, replaced the coil and plug and bought a new Fuel Injector Connector and spliced in onto the Injector "Pigtail'. I double checked everything was reattached properly and let the gasket sealant dry for 24 hours. I went to start it tonight and after trying to turnover it completely cuts out, wont even start up. I'm extremely frustrated at this point and am thinking the rabbit must have gotten to something else unless I did something wrong in the process of repairing.
New valve cover gasket on my 03 VR6 GTI, new plugs, oil filter and cooler seals, new gaskets on the intake manifold and when we started it up . . . .

View 2 RepliesI've got a coolant leak here (I wiped away some of it before taking the picture):
Close up
This is the only place I can find coolant leaking and it's running down all the way to the water pump:
When I wiped away from just below the valve cover gasket it flaked right off and it doesn't appear there is any oil mixed in. I changed the oil today and it didn't appear to have any coolant mixed in either.
The coolant doesn't appear to have any oil in it's nice and pink as it should be. I started the car from a cold start and sat and watched the area waiting for it to leak but nothing ever came out, of course.
I know there shouldn't be coolant leaking from this area anyways but I don't know how else to explain the trail pictured. I definitely have a small leak somewhere as I've found coolant on the floor of the garage before.
Do I just replace the valve cover gasket and move on or is there something else I should be concerned with here?
I just noticed what appeared to be an oil leak around the valve cover gasket, which the VW dealer has determined to be a defective cam sensor. Apparently the VW parts distribution center in Wisconsin has 530 of these in stock, so it may be a common failure. This is on a 2010 GTI with 28,xxx miles. Thought the community would like to know.
View 2 RepliesI'm looking at replacing the valve cover gaskets on my 02 f-250, it's a 7.3L.
Looking at them on line there are many different brands. What have you used on your 7.3L, and which has worked the best for you?
I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.
After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.
Other things which may serve as clues:
Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)
When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.
Car has 107K manual shift.
So my check engine light came on in my 04 jetta sw, and when I had the car read, it gave me a code that tracked down to be a bad coolant temp sensor. I bought the replacement part from my local VW dealership, installed it and the check engine light went away. Now about 2 weeks late it came back on, and I am getting a reading of "Coolant temp sensor high voltage". So it goes from needing replaced, then the replacement is running high voltage?
View 3 RepliesI have a 2002 F250 5.4with Air Conditioning. The valve covers are leaking and the gaskets need to be replaced. I am attempting the valve cover gaskets. I was able to get the drivers side cover off with some difficulty. For the passenger side valve cover. There is very little " no" room to get at the bolts. I read somewhere that I may have to drop the engine on that side. I will do that if I have to.

View 5 RepliesMy 2003 Mk 4 Golf have had a lot of error codes and I have cleared most (O2 sensors, thermostat, and Mass Air Sensor) I now have an error P0113 which is the Intake Air temp Sensor.
So I need to clean the sensor first then maybe replace it, but I can't find the sensor on the intake manifold.
I have looked all through the U-Tube info, but nothing matches my 2003 Golf 2.0L ...
2001 jetta 2.0 VW guys a while back I was pulling a code saying that the air temp sensor circuit was low I believe it was P0112 so I replaced the maf with a bwd maf. Said it was for the car. Was fine for a day but now it has a P0102 code and the epc stays on (rough idle) what could be wrong ? Is it because the car hasn't learned the new sensor yet because I've only drove 10km or do I have a faulty sensor. BTW replacing the maf fixed the P0112 code

I recently got the solid check engine light for my 2003 VW Jetta 1.8T GLS. I used a bluetooth OBDII dongle and Torque Pro to pull the code P0118. This seems to coincide with my symptoms:
Car idle at start in park stays around 1100RPM then in reverse it drops to 1000RPM then back into park and it stays around 900RPM and keeps that at idle.
If I start the car then immediately reverse out of my driveway then the car has a very rough idle but if I wait around 5 seconds in park idle then reverse out of my driveway it is smooth.
My car dash thermometer stays pretty close to the bottom low then after about 4-5 minutes it shoots up to 190F and stays. Gas mileage is also very poor.
I looked up a tutorial which shows the parts needed and how to replace the sensor : [URL] .....
I removed the engine cover and believe I found the coolant temp sensor in the spot the tutorial shows. My question is if there is anything I should be aware of before attempting to replace this sensor that this tutorial doesn't cover? I took a screenshot of what I believe is the coolant temp sensor.
I just got this car it a 2002 jetta glx vr6 12v 5 spleed. It has a miss new plugs wires gas and used coil pack. It misses especially when cold check engine light on says cam sensor changed it and still same thing if I clear the code it comes right back.

I recently did a valve cover repair to stop the dreaded misfire problem. Well, I'm still waiting on a few things but during the spark plug change obviously some of the oil from where the valve cover leaked previously fell into the pistons because I couldn't really clean it all out efficiently. This seems like it would cause a lot of problems? Do you think I should throw old spark plugs in there and let all the oil burn up before finally replacing them? I really don't want to foul up my brand new NGK's.
Also, I pulled p0300, p0305, p0306, so I am guessing oil in the spark plug/coil pack connection may cause some of the misfires, but do you think two of my coil packs are bad still? My plan was to move them around to see what happens after I get the new parts and am actually running again.
