Title: Got to sort this problem PART 2
Post by: Mars Attacks on 14 December 2003, 11:44
Right, this is doing my tits in now.

Car - Golf Gti Cabriolet 1.8 k-jet G-Reg

Problem - Serious lack of power through the whole car.  Engine stutters and hesitates through whole rev range. this is during warm up and when the car is fully warmed up. The car is at its "best, ha" when there are no electrical items on (i.e. lights, heaters, etc...) but as soon as you turn any of these things on, it stutters even worse and power is reduced further.

Its obvious this is an electrical problem. I've tried everything i can think of. Spent yesterday cleaning up all the earths i could find. (rockercover to bulkhead, bonnet to car, earth from battery, earth from gearbox to body looks good) i've also swapped the battery over to see if that would make an imporvement but nothing.

Is there anything else i could be trying? the car has no power at all and may as well be a 1.1 saxo (yes, it's that bad)

can any one help please?!?!

Cheers

Wolfie

Is the rev counter steady when it missfires?, check the rotor arm underneath for tracking down to the dist shaft. Check the air pipes between the metering unit and the throttle body for splits. Is the ign and cam timing correct?.

this electrical problem continues. Any extra electrical item results in power loss, think it may be a dodgy fuel pump as if you put to many items on, it blows the fuse (5 in the fuse box) and car won't start till you replaced it. Had a new lift pump, filter and fuel relay in last months so i'm guessing its the pump that buggered. Any way of checking its electrical draw?

Yeah, stick a 10A ammeter in series. I forget the exact figures but I think nominal current should be around 6 amps and anything above that means its working too hard i.e blockage or faulty pump.

When mine was failing it was pulling 8 amps!

ok i'll give that a go

where exactly will the ammeter need to be stuck to measure its pull.

do you think it is possible that a faulty pump could draw enough power from the rest of the car to make it hesitate when using other electrical appliances?

Put the ammeter probes in the slots that the fuse goes in. Or make up short leads with male spades on and plug them into the fuse box, could put a fuse in the circuit if your meter dosn't have one.

is it not just a knackered earth somewhere?

mine did a similar thing, would splutter and not rev and more electrical stuff switched on it wouldnt run and wouldn start. not sure why though. it was the timing had slipped on mine so played with it a bit and everything was better. the battery kept going flat though but has since stopped for no particular reason.

probably nothing like what yours is doing though

does the battery ever go flat or does it just continue to run but really badly?

probably nothing like what yours is doing though
