It could be a faulty coil pack as mine used to gain and loose power unitl I changed it due to being corroded etc

thanks so far guys.

I drove the car today, no problems at all. Then on the way home after work, once the temp was up alittle in 4th at say 3,000rpm it just started to hesitate

I'm not sure is the cam angle sensor replaced by the previous onwer was actually an original part, also not sure about air mass.

Its jsut very annoying. Any advice really helps

try getting it vag comd if you can as this should throw up a fault

Just had the car plugged into my local garage tech machine (not vw) and its showing mis-fire on ignition number 3.... this leads me to believe its a coil pack

Not using the polo while its faulty and this means the garage cannot look at it until thursday next week

Going to have all the spark plugs at the same time.

Any other advice would be welcome.

[alexperkins]

it could be one of three things

a faulty spark plug

a faulty ht lead

or a faulty coil pack


i had this and it was a broken ht lead

Car goes into my local garage today to try and fix it, not been driving it since they put the fault code reader on it....... gutted I'm hoping its not too expensive to fix as the stealer I got it from is being pain with his warranty conditions.

My GTi was doing exactly what you've described and it turned out to be down to the cambelt tensioner.
After I had the belt and tensioners changed it has never done it again.

I reckon I know the answer to this... but is there any way of checking the log file wotsit without taking to a garage!? After my local garage serviced on Thurs I've had problems, including the the "check" light flashing up on dash.

How corroded do the terminals in the coil pack have to be before you would start seeing problems with the performance? The top ones on my GTi are perfect, shiny and smooth, but the bottom ones look like they are coated in white powder. I got a bit of wirewool in there and some wd40 and they looked a little better - am I better off just buying a new one and being done with it?

if its white then thats signs of leaking, limescale type stuff, i would get a new one!
