My vehicle stalls everytime i take off after being stopped at a light, stop sign etc. I have had the alternator replaced, the engine flushed, the cooling fans and censor replaced and still no success. I have even bought a new battery. Any suggestions. Its a 2004 volkswagen beetle.

any engine codes if so have the vehicle for engine code --your problems can be from a numerous of reasons--check fuel pressure filter can be clogged or partial clog --vacuum leak check hoses --throttle body may need recleaning or sensor going -- egr valve carboned up ,damaged or circuit problem inspect it if carbon clean valve or replace if broke --bad load of fuel --needs tune up -air filter clogged

Sounds like your serpintine belt came off or is really slipping on the engine pullies...

it is a safety fixture for people like you, who do not respect gauges, if the lite come on is for a reason, too hot or nor oil pressure, well do that in some engine, obviously you did not respect the signs. that this make sense to you !!

Question, does this pickup blow black smoke on idle or at a stop sign. If so check your map sensor might be plugged up or unplugged or bad.

It sounds like your alternator is dieing out, or you have dropped a belt (should overheat though) With the vehicle running, remove the posative cable from the top of your battery and see if the vehicle stalls. If it does it's a good sign your alternator is no good.

Do you have more information? Such as, does it do this every single time you are stopped? Does it ever happen when you aren't quite at a complete stop? How soon does it stall after stopping at the light (right when it's completely stopped? As you apply the gas to move again?)?

Mainly a vehicle will stall do to a problem relating to the fuel/air system. Specifying any 'special conditions' (very hot, very cold, etc.) when the stalling seems to be more prone to happening (if any) will help with a diagnosis.

It could possibly be a bad/faulty fuel pump, where the engine isn't getting the proper flow of gas (in a case like yours, it would most likely be an intermittent flow).

Also, a faulty throttle positioning sensor (TPS) could be the problem. These are a somewhat 'run of the mill' problem in vehicles in general and aren't overly expensive to replace. This is even more likely the problem if your vehicle stalls when you are taking off from the stop light. This isn't difficult to test yourself and there was plenty of directions to do so online and elsewhere.

A vacuum leak is another possibility. Another symptom of this can be a high idle (higher than usual for your vehicle at least).

Lastly, I wouldn't imagine this to be very common but it's worth a look, and i only mention it because it was the problem with my '87 Celebrity that suddenly stalled at a stop light, then kept stalling whenever i pressed the gas to move. The car had a known engine oil leak, one area of which it effected being the air filter housing (old-fashioned circular one). I noticed, once i finally got moving (albeit only for a short time before stalling again) it sounded as though the engine wasn't getting enough air. Even though i had just recently replaced the air filter, i checked it and found it was completely covered with dirty engine oil. I took out the dirty air filter and it solved it. It just hadn't been letting enough air through. So, simple solution though not commonly the case. No harm in checking anyways.

Good luck.

oxygen sensor

First suspicion - TPS (Throttle Position Sensor)

this is the cause.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

check the mass air flow sensor it is hooked with air cleaner
