bog standard g40 hesitating at 3/4k

[hooblah]

i recently bought a bog standard low mileage g40 that was sat in a garage for a few years. i drove it before servicing it and it was a bit iffy and there was a bit of hesitation at 3/4k. now ive just given it a full service and its still doing the same thing.
when you put your foot down it boosts up alright, but then when it hits 3/4k theres a slight hesitation and then it starts pulling again. oh it hesitates twice between 3/4k.

could it be related to fueling? i was going to change the fuel filter but vw told me it was a non-servicable item...

cant see it being the leads, cap or rotor arm as it would be a constant problem.

can anyone help?

Could be your dizzy/hall sender?

[hooblah]

how would i check this?

[hayesey]

is the hesitation a misfire?

[hooblah]

i guess so. what else could it be?

Fuel filter is a metal can under the car by the drivers side rear wheel. They are most definately replaceable and cost about a tenner. I changed mine when I first got the car as it had corroded a bit and was dripping out petrol.

okay i'll give that a go, but i cant see that being the cause of my problem.

Maybe check your boost pipes for leaks. Just make sure they are secure.

lol boost pipes. i think you need to do a bit of reading before giving advice like that

mine used to do that,

i had the timing set properly as it was out slightly and that sorted it out.

Sorry next time I'll recommend to go replacing every part under the bonnet. Rather then checking simple things. Especially when that is the only thing that sorted my car out when it was playing up.

If you did some reading you'd know that the fuel
Filter is replaceable. I swear some people on here think they are the dogs danglers.

some people do have brains and sometimes simple things arent always the answer. if there was a boost leak then you would notice a decrease in performance throughout the revs. it helps to know what youre talking about and to whom youre talking to before giving answers.

for the record, i was advised by vw that the fuel filter was non-serviceable, so why would i feel the need to look into it further?

anyways. back to the problem solving.

ive been told it cant be an ignition problem as unburnt fuel would get dumped into the exhaust which would cause backfiring. whether this is true or not i dont know.

Whoever you spoke to at vw is wrong. The fuel filter most certainly is a serviceable part on a g40 as much as any other car. Well worth doing if it's as old as the car, a blocked fuel filteer can potentially destroy your engine.

Obviously your vw garage didn't know to whom they were talking to and didn't know what they were talking about did they? Go and lecture them about doing their research. Speaking of know whom your talking to, you have no idea what I do so don't judge my intelligence. Your here seeking advice and I was giving a suggestion. 

Why don't you go to this expert that is giving you advice and get them to put it on a gas analyser to see how it runs through the rev range or actually test your ignition before you reject it as the cause?

i'll change the fuel filter on monday and take a look at the dizzy. if i cant solve it then i'll be back.

cheers guys.
