They are both on the intake tube about 6 inches from the air filter and there is a single plug that attaches to it. Hope this helps.

I have had many engine light codes that have to do lean/rich fuel ratio, misfires in 3 &6 cylinders, something about the O2 sensors. But before this I had replaced the cylinder pack, wires, spark plugs, and the catalytic converters and o2 sensors along the passenger side, and one post catlytic converter under the driver side. I'm at a lost for how to stop the jerking that happens between 30-40 mph. please help me! Hello,

If I accelerate hard the CEL flashes until I slow down and let the engine level off. Once I get up to the speed I want, the car runs fine until I go to accelerate again. I have changed the spark plugs and it was a little better but is back to the same thing again now.

What a disaster that was! Immediately after it was fixed, the car started misfiring. I changed all plugs and coils and it was fine for a few days. Now when I start the car it idles fine, but when its put into gear and driven, it starts to misfire once I hit 3rd, 4th and 5th. In turn, the exhaust malfunction light(looks like C.E.L.) flashes until i stop. Once I stop, the light stops flashing but stays on. Once it gets real warm, it starts misfiring in all gears. It is still throwing misfire codes!!! What am I doing wrong? Any ideas?Thank you for listening My 2005.5 jetta value edition’s coolant temp sensor kept popping out causing overheating.

The locks all dont lock and unlock (esp the rear ones). I've noticed when driving at night that the headlights dim and the lights on the a/c controls will turn off or on. It was turning itself off when i came to a stop then restarting automatically. tonight it turned the engine off at a stop sign and had to turn the car off then back on. Sometimes when i turn the car off the lights inside and out and radio turn off before i take the key out or turn the lights off and it'll reset the odometer and clock. I had the alternator replaced cause thats what one mechanic said it was. Didn't fix it. still turned off when coming to a stop. The battery is new and has no corrosion. the dealer i'm buying it from cleaned all the ground wires and it solved it for a time but now its started again. Any ideas how to fix it? i've heard it could be the BCM or a short in the wiring somewhere in it. Help! I'm scarred to drive it long distances since i frequently drive to atlanta (260 mile round trip for me) Hi! i’m paying on a 2003 Jetta GL and have been having electrical problems with it since i got it.

Now the check engine light is on and the car is sputtering at traffic lights...i have to throw it into neutral because if feels like it wants to die. I just had to put a new battery in it about 3 days ago...really hope its not the alternator. Any ideas? 2000 Beetle–I live in South Florida and the other night the streets got flooded from a storm.

I have a question and I hope someone can help me out. I have an 05 vw golf tdi 1.9 hatch. What is happening is, whenever I accelerate, my turbo/engine bay sounds as though it is loosing air somewhere in there. I checked my car with a OBDII reader and it said I had an error code 16683 ( Boost Pressure Regulation: Control Range Not Reached). Is there a way to fix this without having to go to a mechanic? Who said chics can't get under a car? Smile. Please help, anyone? Hello fellow Vdubbers! I have a question and I hope someone can help me out. I have an 05 vw golf tdi 1.9 hatch.

I went to start my car after it sat in the drive way for an hour and the CEL would not start blinking; the engine was running super rough. I thought I broke the motor mounts and that perhaps the lifters went bad because of the noise. I let the car sit overnight. The next morning I started the car and the engine was as smooth as a brand new car; the CEL was now solidly lit and would not turn off. Again, I let it sit for a day. It drove perfect for the next 3 days before the CEL started blinking again and it started running rough again. It is at the dealership now but I am told they cannot do a OBD to read the codes and cannot figure out why. What can the problem be with all of this??? HELP!

I had the thermostat and ETC replaced and its still throwing the same code. And sometimes when I start it (or try to start it) it sputters to life (usually after a few tries) and the RPMs go up to and stay at about 4000 and when I hit the gas she stalls.
