losing power vw polo

hi my daughters car seems to be loosing power when your driving it.when you change the gears there is a drop in speed.it was serviced on saturday and the mechanic says it may be the distributer speed sensor.can anyone let me know would this be the problem.:confused:

babs rather than spending time looking around looking for answers to your problem,I would if it were me go and get the car diagnostically tested there are so many issues in the modern day car regarding sensors it could also be one of a number of other issues,i recently had to get my own car plugged in due to something similar,if the fault shows up then you are getting to the heart of the problem immediately and not replacing parts that dont need to be replaced,the down side is that the ecu (engine control unit) can clear the faults itself and you could find that nothing will show up on the diagnostic test,so try and get it tested asap,sorry for not being more helpful,if i was to list what i think could be wrong then i would just be speculating.

thanks moh i will do that and let you know we had a problem like this before and it was some sensor.the mechanic says it maybe a speed sensor.

No probs babs hope you get it sorted i would be very interested to know what the problem is,let us know how you get on

whats the year ?diesel or gas? by losing power do you lose rpms at the same time?any codes displayed?please post back with this info.

thanks aldan its year 2000 and runs on gas nothing is on the display and when you go up a gear it seems to be slowing down.

distributor speed sensor should post a code.have it scanned for codes and maybe a fuel pressure test.half the battle these days is finding a reputable shop.never heard of this model,im in canada tho.another thing to look at is the caylitic converter.pull one of the o2 sensors and see if it runs any better.if it does you may have a plugged cat.cheers Al.

thanks aldan the distributer speed sensor was mentioned so i will get that checked out and let you know.

dont see many cars running on gas,petrol yes,diagnostics first i think.

hi cacti aldan is canadian so it gas there petrol here.we think its the speed sensor i will let you know when we get it sorted.
