Passat (B7) :: Filled Up First Tank Of Diesel - Check Engine Light On

The car is great. Filled up with first tank of diesel last Sunday. About 100 miles into a long ride east, the CEL came on without explanation. I double-checked the gas cap, and it had been replaced properly.

Passat (B5) :: Engine Check Light On And Throttle Start Surging - Water In Tank?

Coming back from Busch Gardens today. Filled up at a Shell. Got on the road and within minutes got a check engine light and the throttle started surging like when you have water in the tank (know from past experience-don't ask). Is the check engine light what would come on if I had water in the tank?

I was able to make it home after adding one bottle of dry-gas but the car is still doing it...major loss of power during mid-level throttle. I was able to keep the engine light from coming on if I was very careful with the throttle and kept the revs around 3K or higher.

Hate to take it to the stealership if not necessary. Burned 1/4 tank of gas on the way home. Should I add a second bottle of dry-gas and top off the tank with fresh gas before taking it in? Don't want to damage injectors or?

Chevrolet - Equinox :: Engine Light Always Comes On With More Or Less Than Half Tank Of Gas

I have a 2006 equinox with 74000 miles that consumes up to 2+ quarts of oil every 2000 to 3000 miles between oil changes and the water in the fluid section of the car drops about one gallon of water thus causing the car to over heat what could be the problem. The engine light always comes on when i have more or less then 1/2 a tank of gas. The manual said this could be the gas cap that is producing the problem and is there a solution.

My 1999 VW Passat has a check engine P0411, P0422, so I looked for any damaged vacuum lines and found one that was all melted coming out of the blue vacuum reservoir tank in the front left lower bumper area. The line was broken off and I cannot figure out where this line is supposed to go.

Toyota - Rav4 :: 1998 - Check Engine Light Came On When Gas Tank Filled

I have a 1998 Toyota Rav 4 with apporximately 140,000 miles. When I fill the gas tank the check engine light comes on, the engine runs rough (like a misfire). Diagnostic code comes back a "lean mixture,bank 1". When the tank reaches approximately 3/4 of a tank the light goes out and the engine runs smooth and fine. Then, when the tank reaches just belwo hal a tank the light once again comes on and starts running rough again. Have drained the tank, used dry gas, Startron to counter the ethonal etc. Nothing seems to work.

Mitsubishi - Galant :: 2004 - Check Engine Light Came On When Putting Gas Into Tank

I loaned my car to a friend for 2 days. While driving, she allowed it to run out of gas. The check engine light came on as soon as gas was put into the tank and has never gone off. I now need to get inspected, but afraid it will not pass. Someone said to put "Garanteed To Pass" in the gas tank. I have never had any problems with this car. I am the original owner, and I keep the oil changed and the filter clean. The car runs perfectly with 120K miles! What should I do?

Ford - Explorer - F250 :: 4.9L Engine Gasps For Gas At Half Tank

I recently acquired a 1983 F-250 regular cab with one previous owner and a known issue...the engine heaving for gas once it dropped to the half-tank mark.

Both fuel pump and fuel filter had been recently changed, among other small maintenance adjustments including new sparks and wires. In driving it down from the mountains following the vehicle transfer, the engine completely died at half tank. I then poured 2 spare gallons into the tank and it started up and finished the journey home. Prior to arriving home, I filled the tank completely and it only took 6 more gallons (19gal tank). So this doesn't seem to be an issue of a fuel gauge malfunction.

I'm perplexed. How is it that it can run fine at full tank, but upon reaching half it begins to sporadically shudder, as if not getting enough gas? If I continue to run the truck beyond half, it will stall or not start at all. Put a couple more gallons in, and it starts right up. When it's on half and won't start, it still fires with starting fluid. I suspect there's an air leak in some component in the tank.

Prius (2010-12) :: Check Engine Light / Code PO0456 - Entire Gas Tank Needs To Be Replaced

2012 Prius Gen III 38,000 miles, check engine light came on. Drove car to dealer and they came up with error code 0456. The explained that a rodent (I live in a rural area) chewed on a hose which is causing a leak like a bad fuel cap.

To solve this problem they recommend that the entire gas tank needs to be replaced. Does this seem reasonable? It seems to me they are saying that the chewed hose can not be replaced.

Passat (B5) :: Check Engine Light Came On After New Engine Installed

Okay, I bought this car used and the previous owner apparently didn't maintain it. So I spent the last couple months having a new (used) engine installed. All said it's been in the shop longer (by twice) than I've been driving it. On the way home from the mechanic the check engine light came on.

If I keep changing my oil every 2000 miles will it sludge again? Dealer recommended every 1500 to 2000 miles! I've spent 15k on this car so far, and driven it about 2k miles......
