MK3 Golf GTI 16V Stalling below 1200rmp.......
« on: 26 October 2012, 11:34 »
I have recently rebuilt my ABF and started her up, only to find that she cuts out as soon as the revs drop!

The engine was stripped of all ancillaries, everything was either cleaned or painted, and then refitted with new gaskets and new bolts. I filled her up with manufacturer spec oil and coolant, checked all the loom for damage (repaired a few cracked wires) checked that there was power at all the plugs, checked all the fuses, checked all the appropriate relays got warm after driving around for 15 minutes and thoroughly cleaned the ISV with degreaser and then sprayed with WD40 (the ISV clicks with direct current from the battery but then silent when connected).

I have replaced the white coolant sensor, the crank/speed sensor and vacuum lines, the air and fuel filters were replaced just before I bought it.

Before the rebuild the engine was suffering from hesitation and lack of power around 3000 rpm and cutting out at high temp and were showing an ABS fault and a crank/speed sensor fault. All bar the ABS fault seem to have been cured. Also the oil hazard light is blinking on ignition but clears when the cars started and the oil temp shows -- -- on the clock display, however I believe this is just down to the spade connector snapping on one of the sensors located on the oil filter housing.

Any help would be greatly appreciated as I have only had the car for 4 months and 3 of those has been the rebuild lol!

Cheers.

Have you hooked it up on vagcom, to see if faults are showing?, I'd say try that as first bet, then take things on from there

Have you reconnected all the vacuum hoses?
And crank breathers?

I have the VCDS Lite version, only came up with the ABS fault (Which is next on the list to sort) Also, as a correction from by first post, with the ignition on, I can hear the ISV buzzing, so it's definitely working.

Yep, all replaced with silicone versions as well!

I still think ISV to be honest. Can you 'borrow' one to test that you know is working?

Does it run normally with the revs above 1200?

I'm trying to find someone with a 16v who is near by at the moment. Before hand it used to idle around 1000 rpm. It's between 1000 and 1200 when it drops off and cuts out :(

It's just weird, I can here it click open and shut from direct current and with the ignition on I can hear it buzz so it should all be working ok.......

Have you checked the throttle stop switch wires, and the switch itself?
