I recently had a Jasper rebuilt engine installed in my Ford E150. Since than my check engine light keeps coming on and the computer is saying my cas air mix is "lean". The instaler says i need a new fuel pump.Another mechanic says it is more likely a vacuum problem.I know it's possible that the fuel pump is bad bur since this has just started since the install, I don't believe it can be the fuel pump unless it's just one hell of a coincidence.

Volvo :: Vacuum Leak - Check Engine Codes
Just bought my volvo several days ago. It was throwing check engine codes so I had it scanned and it came down to a vacuum leak. I found the spot where it was leaking which was a little piece to the left and slightly behind the exhaust manifold, slightly behind and beneath the thermostat housing. It went from a hard plastic vacuum line, to a 1.5 inch rubber vacuum line which plugged into a nipple on the exhaust manifold or something behind the manifold. the rubber section had 3 large holes in it, so i replaced it with more rubber vacuum line. same length and same inner diameter.
What I did notice when I replaced it was that it was too large for the plastic line, slid on way too easy, but i had to fight it onto the nipple. The check engine codes went away for 2 days(I drove about 150 miles over that time) but today, the check engine light came back on, went to auto zone, had them scan it, came back with vacuum leak. So when I got home, I popped the hood, sprayed some carb cleaner by the replacement vacuum job I did, and sure enough the idle changed. What the proper replacement hose is for that area?

Passat (B5) :: Vacuum Leak - MIL Light Came On
We have a 2001 Passat with a 1.8T engine. There is a small vacuum hose at the front right fo the engine attached to the manifold that is cracked where it attaches and leaking. I'm fairly certain that this is causing the MIL light to come on. The clamps that hold the hose on look to be put on with some sort of custom VW tool. I'm going to replace this hose myself. What to use to reattach the new hose?

Regarding photo - The area the hissing appears to come from is located in the rectangle area, more or less.

Passat (B5) :: Check Engine P0411 And P0422 - Vacuum Reservoir Tank?
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.

View 5 RepliesToyota - Avalon :: Check Engine Light Stays On
The "Check Engine Light" is on. When I brought it in for the annual inspection (NY), the diagnosis was "lean fuel mixture". The fuel filter was replaced (the car has over 110,000 miles on it), and some adjustments were made in the computer, or the sensors (I don't remember which). It was found that one adjustment was effective at low speeds, and the other one was necessary for 2000 RPM. A valve cover gasket was replaced because of an oil leak, but I don't see how this could have contributed to the problem. I drove it for about 10 miles and the light went on again. What the cause might be?

I have a 2001 Chevy S10 4.3L. The CHECK GAUGES light stays on, and the oil pressure gauge stays at 0. The oil is full, and the engine runs and sounds fine. I drove it about 5 miles with no change. Up until now, the gauge has worked normally. Could it be the sending unit?

The check engine light stays on. The hood of my car was not securely locked when I purchased it, I'm sure it's due to an accident because it's damaged. Can the hood be a reason the check engine light stays on..it does not blink.
View 7 RepliesJetta - Volkswagen :: 2001 - Check Engine Light Stays On
I have 2001 Wolfsberg Edition 4D jetta (gas) with 180,000 miles, manual transmission. The engine light has been on for years and years. Usually what I do is take it in for an oil change just before a smog. They re-set the codes. I drive it to my office and back and the light would stay off and I could smog it. Until recently. In April, I took the car in for an oil change. And when I picked it up, it ran terribly. It was lurching like crazy. I had to keep slip the clutch to drive it until it warmed up and the it would mostly start running OK. I took it back to my mechanic and he thought it was a timing belt. I had already changed the timing belt at 119,000 miles.
It seemed odd to me that this procedure needed to be done again after 60,000 miles, but I went ahead and had it done. That did not fix the problem. Then the mechanic replaced the air mass meter. That didn't work. Then he replaced the coils. That didn't work. My mechanic has had the car for a month and can't seem to figure out what to do. He keeps getting different error codes - codes that don't seem to make sense to him. The car needs to a smog (my registration date is June), but he can't smog it because we can't get the check engine light to stay off long enough.

View 7 RepliesAccent MC (2006-11) :: Check Engine Light Flashes Then Stays Solid
My wife was about to go into work today and when she started the Accent she said it started rough and revved up two or three times and the check engine light flashed 5 or 6 times. The light stayed on solid after that but there was no loss of power, smoke, low gas mileage or vibrating or any other symptoms after initial start up. I plan to take it to an auto parts store tomorrow (the car is at her work about 20 miles away) and get the code read. What I may be in for? I'm hoping its something simple. I told her to check the gas cap just in case.

My 2002 Hyundai Santa Fe 2.7L V6 AWD failed to start a week ago. After towing to my neighborhood repair shop, it was diagnosed as a faulty ECM based on code P560 (System Voltage Problem). They replaced the ECM (along with relay) with a used one with the exact same part#. After that, the car was started and run OK but Check Engine Light stays on all the time. The codes displayed are:
P1529 TCU MIL Request Signal
P0501 VSS Range Performance
I was told that this is caused by the fact that each ECM is VIN/PIN locked. The replacing ECM was used in another car before and was locked with a different VIN thus cannot communicate with some components of the current car.
My questions are:
Can this used ECM be unlocked and relocked with a new VIN/PIN? If so, does it require the previous VIN/PIN to unlock? Most likely the previous VIN/PIN is no longer available.
Does this service require the presence of the car or can it be done with the ECM alone? Do keys need to be re-registered? The car starts fine currently.
Accent MC (2006-11) :: Rough Idle - Check Engine Light Flashes And Then Stays On
I just bought this car from the original owner. She didn't take that great of care of the car. First oil change was done at 8,000 miles for example. Basically if it was broken she would fix it, but didn't do much preventative maintenance.
I just replaced all 4 spark plugs and coils since one was misfiring and didn't want to have to go back in and replace one in another few months. Replaced the AC belt a few days ago since it was cracked and worn. All other belts are fine. I drove the car around for a few hours the next day and it ran great.
Today, the check engine light flashes and then stays on. The car is idling rough at stop lights and acceleration is poor. Previously, the light came on and it was the EVAP system. Not sure which component and I was told it isn't supposed to affect the way the car drives.
