G40 stalling/idle problem.

[vwmk3jon]

Trying to pull away is dodgy to say the least! Its almost like its got a fuel defiency and then suddenly wham, the power picks up. Need them wiping off the chip really.

Deffo the map on the chip.

tbh, you'll get a bit of that with the eaton as its all top end power

[vwmk3jon]

surely not as bad as mine though? Its like my 1st ever car, the carb would get shit in it and cause me to be stuck at 5mph. thats what it feels like! sometimes i can drive through it, sometimes it stalls.

[hayesey]

sounds like it's running lean at the bottom end.

[PeteG40]

1341 g40 eaton i drove was like a gt/stock g40 pulling away, then you got to 4k and it went like stink, only to change and be the same... mind you car was a bag of spanners

[hayesey]

yeah I wouldn't judge it by that one you had pete, I dread to think what the fuelling on that was like.  Seeing as how the "remap" on it seemed to consist of an adjustable fuel pressure reg.

[hayesey]

I would say "aint so bad".......but it was.

[vwmk3jon]

This pulls away like a stock cube! 5/6mph max!

Hayesey's car was deffo in need of mapping - yours may be the same. I'd only commit to spending money on a remap once you're 100% sure that everything else is in good health though.

[vwmk3jon]

im gonna get the coil changed along with the pulley to a vernier but ive gotta get it working first so i can get the bottom end checked to make sure its not fubared! injectors, plugs, gaskets, sensors are all new.

[Andy]

A compression tester should only cost £20-£30, that'll tell you a lot about the bottom end. Did you sort the suspected alternator problem?

[cheddarcheese]

back on topic hijackers and what's my problem or and possible courses?

[vwmk3jon]

mine used to be the same. i cleaned the ISV out and checked the CO pot. we adjusted the screw on the t/b too and it ran better.
