SOURCE: 99 vw passat, when running, MIL lite, on car vibrates- shakes

no flashing light and rough shaking will be part of spark plug but also a very bad miss fire. I am going to guess that your engine is a 1.8t if so you have 4 coils that sit on top of your spark plugs that most likely are arcing you will need to figure out which coil is failing or you can save yourself the trouble and replace all 4 and the spark plugs. before you do that though check your wireing going to your coils look for broken wires or the ground that is next to the #1 coil that is the one closest to the front of the motor and you. hope that helps. that will be the start to fixing your issue also when you pull out the spark plug look down the hole first and make sure that there is not oil in the bottom of the hole if that is the case you will need a valve cover gasket as well. good luck hope that helps

SOURCE: Error Code

P1300 Misfire Detected, Fuel Level Too LowIf the low fuel level is not the case check for a dirty heat sink for the ingintion/igniter module or any other source of a misfire, if you have run out of gas this could cause the code as well

I would trust them but make sure it is just not in need of some kind of cleaning.

You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.

Lean code cel flashing and lack of power what is the most likely csuse

You will more than likely not notice any drivability problems, although there may be symptoms such as: a lack of power detonation (spark knock) rough idle hesitation/surge on acceleration. Causes A code P0171 may mean that one or more of the following has happened: The MAF (Mass Air Flow) Sensor is dirty or faulty Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak downstream of the MAF sensor Possible cracked vacuum or PCV line/connection Faulty or stuck open PCV valve Failed or faulty oxygen sensor (bank 1, sensor 1) Sticking/plugged or failed fuel injector Low fuel pressure (possible plugged/dirty fuel filter!) Exhaust leak between engine and first oxygen sensor Possible Solutions A lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include: Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect all vacuum and PCV hoses, replace/repair as required Inspect all hoses and connections in the air intake system Inspect and/or test the intake manifold gaskets for leakage Check for a dirty fuel filter and proper fuel pressure Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool If you have access, you may want to run a smoke test

1999 passat check engine light on and low idle

Best bet is to plug it into a code reader to see what the computer believes the problem to be. Only takes a few seconds and should be next to nothing in cost. Best guess is that the front O2 sensor in your air intake needs replacement. Other possibilities are clogged fuel filter or even worn out spark plugs. Need that code number to pin it down accurately.

Rough idle and smells like gas when driven

When checking for Vacuum leaks, did you use a water spray bottle on seams and vacuum lines and EGR pod?(engine running)

Check for air leaks in exhaust before O2 sensors. O2 thinks its running lean from air leak in exhaust header and enrichens fuel charge.

Fuel injectors dirty, not closing tight. Switch injectors to other bank and see if Error Code moves to relocated injectors.

Bad spark plugs, check if you have fuel runners in your intake.

Keep getting same 3 codes, MAF, random misfire and EGR I have replaced air and fuel filters, Mass air flow sensor, cleaned the EGR and reinstalled, replaced plugs which were old, cap, rotor and wires all...

No vac leaks...have you put a vacuum gauge on a manifold tap and checked the vacuum reading? Vacuum should be steady at 17-22 inches. If much lower than that, below 15 inches, you may still have an air leak-check the intake manifold gasket, and throttle body assembly gasket. Spray carb cleaner around the sealing areas while engine running, listen for rpm surge or change in pitch. Does the big air boot have any tears or punctures, and is it clamped down tight?

What is the fuel pressure reading? Does it match specs for your vehicle?
A cylinder compression test may be called for if you cannot find any other reason for the misfires. Look for low compression figures that may signal a valve problem, or valve timing problem.

1999 Chevy G-30 utility van code p-0174 , cleaned then replaced MAFcleared code, back on 50 miles later, found vacum leak hose off vac. ball, code cleard 50 miles light back on,

what size engine do you have in the g-30 van. is it the plastic plenum. if it is there are rubber o-ring seals that go bad all the time and will cause the p0171,p0174,p0172,p0175 these are all lean codes also check for fuel pressure to make sure it is up to specs.
have you changed your fuel filter lately this can effect fuel trims.

Codes for 1999 passat p1300 p0103 p1416 and p1545

P0103 Mass or Volume Air Flow Circuit High Input P1300 Boost Calibration Fault,P1300-P1399 - Ignition System or MisfireCode Description P1416 Port Air Circuit Malfunction/ (AIR) System Bank 2 P1545 Probable Causes:1 - Failed Throttle Actuator
2 - Failed Throttle Valve Control Module
Look for broken hoses, vacuum lines, leaking gaskets, anything that could cause air to escape. Check your vacuum lines carefully by using a propane UNLIT propane torch and go around every single vacuum line with the engine running. If the engine rpms increases, you have found the leak, check for any connectors that may have become unplugged or burnt or broken,, It appears that you have a circuit loss,, check the fuses
