My volkswagon jetta TDI loses power when i am accelerating. i noticed that it usually happens just before i get to 2000 RPMs in every gear exept first. what could be wrong?

    i added injecter cleaner to my fuel. i forget what brand, and it ran good for that tank (as expected) and it does lose power much less often than it did before. Im going to run another bottle through and see if it gets any better. thanks again for your help goeffreyh

This may not be the answer you want but as all vw product are computer controlled you are best to get a diagnostic done at a dealer that has the machine(a proper vw one)you dont have to get them to do the work but its so simple once diagnosed correctly.....and a small price to get the correct info first time.
you can buy the all in one type,but they are not available here in the U.K.so i dont know if they are any good...
i am a fully qualified technition but still go to my local dealer for it to be done(cheaper than buying a diagnostic )

    it was a good idea, i have a volkswagen reader, all that it read was a glow plug malfuntion which i already knew about, but it has been reading tht for years now and there was no power loss. if you have any other comments i would love to here them.

    as it seems to happen when you have no real load on the engi(first gear)could it be a dirty injector,i would try redexe or similar to see if it helped..but i am clutching at straws.....

    I added a bottle of cleaner to my fuel. as expected it worked fine with that tank of fuel. And it hasnt been loosing power as much any more, it rarely ever happens, but still once in a while. Im going to run another bottle through... see if it helps more. thanks again goeffreyh.

it sounds like a wire is bad/ shorting out. Put it in a dark garage open the hood have someone start it while you look under the hood if they give it a little fuel you will see an arc from the bad wire.

2002 Volkswagon Jetta not accelerating like it use to. Has no power

Mass airflow sensors commonly go bad on these vw's and can give you lots of low power problems. If the car has been tuned up and not running poorly I would start there.

Easy DIY is to change all fuel, air, and oil filters, do full tune-up, and change ignition cables, too. See if problem goes away. Take a look at coil, too, those cars have a known coil issue and it needs replacement every 25,000 miles
