WTF is wrong with my VR6???

Driving home this evening, car not feeling quite right, didnt start well at all, feels lumpy.

then all of a sudden power just cuts out, back off the accelerator and power jumps back in, until i get to about 2000rpm and it goes again.

Limp home a bit like this and then it all seems to turn back to normal.

Any ideas?? [:^(] [:^(] [:^(]

Could be jumping teeth on the cambelt.

 

or sh!t in the tank or fuel filler

 

i dont think it has a cam belt, VRs have a chain, dont know if this can jump?

 

might be poo then.

 

A dodgy earth connection?? Had it before on a different make of car though!! Could even be the dis cap arking across the leads

yes it could, you can cause transients that can damage your ecu if it was not done done properly, dont think this would cause your problem though, so im bugger all use

 

Mine did something similar when the ecu was knackered.

Wouldn't rev over 5000 then when i let off the gas i got a boost of power



[TIP]

I would edit your first post and put "VR6" in the title to draw the attention of Phatty, etc...

 

Help me phatty!!

Really hope ive not fried the ECU trying to help jump start my housemates piece of crap car.

Im hoping the poo in the fuel tank is the cause. I filled it up today as it was getting fairly low and it seems to be running better now, still feels a bit odd though.

 

could be the connection on the ECU and if the grounding is bad it could fry your ECU!!! better check it out!!

 

He's not on today, hes doing a vr swap for one of his mates

 

you need to start by getting the diagnostics checked.

could be loads of things, ecu, coilpack, ht leads, cam chain tensioner letting go, etc.

 

I had a BMW that used to do this, it was the catalytic converter in the end

 

what year is it? does it have a coil pack?

 

Its a 94, so yep it has a coil pack AFAIK

 

Try an ECU reset - disconnect the battery for 10 minutes - and if the fault is still present after a good run then you need to get the car on VAG-COM.

I will give it a read if you can pop round. I live near Manchester.

 

Is that offer open to anyone close by I hav'nt got a problem, but its good to bear in mind

 

Thanks for the offer steve, but i live in southampton mate, bit of a trek up to manc. didnt know u could reset the ECU that way.

 

I bought VAG-COM when I had a Corrado and will help anyboby nearby with a reading as it sits doing nothing now I have a Mk2. I have an OBD style connector so can read any OBD2 VW/Audi from the early 90's on. As I say, I live near Manchester.
