Guys...I'm after a definite answer here. I've heard of both ways, but which way do you turn the AFM screw to lean it out...Clockwise (higher resistance) or anti-clockwise (lower resistance)?

So turning clockwise will increase the resistance which will 'richen' the mixture, whereby turning anti-clockwise will 'lean out' the mixture.

cheers mate...you're sure of this? There is a lot of conflicting evidence, thats all

Multimetered the craaaaaap out of my AFM this arvo, pins 1 and 6, raised the resistance, like lots based on advice from a mechanic who previously had them from 380 ohms to about 490 ohm, i think this had leaned it WAAAAY out. Any tips?

my vl has only just developed a missfire so i checked the crank angl sensor cap took it off then i put it back on and and the spark got worse and now it doesnt even spark at all from only just touching the plug do you guys think it might be a dogey wire in the plug or wiring harness???? or is it the crank angle sensor??? any help would be much appreciated ---------- Post added 12-11-10 at 19:02 ---------- Quote: Originally Posted by adz24888 [View Post] my vl has only just developed a missfire so i checked the crank angl sensor cap took it off then i put it back on and and the spark got worse and now it doesnt even spark at all from only just touching the plug do you guys think it might be a dogey wire in the plug or wiring harness???? or is it the crank angle sensor??? any help would be much appreciated i changed the crank angle sensor and now it still has a missfire and runs like **** ive done the fuel filter changed plugs changed leads changed the water temp switch changed distributer????3 weeks before i put a bigger fuel pump in a bosch 044 but i didnt change the fuel sender inside the tank could this be the problem???????????or could this be signs of a headgasket letting go? theres no water in the oil cheers

after all that the number 1 injector was blocked

Hey guys, up until yesterday the vl was idling and runnign mint, replaced 2 broken manifold studs today and when wiring the dizzy back up i hooked it up clockwise instead of anti clockwise and tried starting it several times, realising what i had done wrong i swapped it back and it started then stalled while idling, then it wouldnt start at all, and now its starting every now and then and if i leave it to idle itll run for maybe 30 seconds then just die like its getting no fuel, if i give it some juice when it actiually manages to start it splutters or pulses or sometimes just dies occasionally it wont pulses or splutter but instead makes a sound like its missing, you can hear a murmer from the exhaust when its idling gets louder just before it dies. I have done a diagnostics test which returned 21 (ignition system) if that helps... What's wrong?? ---------- Post added 30-01-11 at 11:22 ---------- My afm is giving just .02 volts on the 3rd wire... is my ecu stuffed?

GAB did u find the problem

hey mate, not yet she still parked lol, waiting on a new xover pipe and afm will update as soon as i get it running

Then my friend came round and jiggled the fusebox, the fuse rail was loose enough to jiggle round and cancel connection for the ignition fuse intermittently, thus killing the engine. This resulted in the ECU displaying the code for Ignition also. Most definitely even if your fairly sure its in good condition take out your fuse rail and inspect it for corrosion or bad connections on the ignition fuse. A very frustrating thing that one was. Replaced many unneeded parts. Never heard the end of it from my friend from that one haha. Some original photos have not been recovered yet.

Thanks for the info! I should have updated this ages ago ha ha, afm wire had snapped. New crossover and afm got her running again Some original photos have not been recovered yet.

New crossover and afm got her running again did you mean the hot wire? Im experiencing similar problems with an engine i just installed in my vl as the ones you said from before.the cutting out and running like a bag of ****, missing etc.. Some original photos have not been recovered yet.

Yeah hot wire! Was good for a few months, but in true Vl fashion having fuel issues now haha. Gotta love them

Even with the hotwire broken I didn't get an error code. If you can get it to idle try unplug the afm and you should be able to hear the revs change. If you can't get it to idle try get hold of a known working afm $10-20 on this site and swap it in.

Thanks ill check that out also.

my afm is currently reading 1.26V meaning borderline lean, tried turning the adjusting screw clockwise but nothing changed... where do i go from here ? Some original photos have not been recovered yet.

too late now but for reference years ago when i wired up my CAS i mixed up a wire and blew the fuseable links. These are the little ones coming off the +ve battery terminal. from memory light green wire and orange. you can swap this for one off another car in 1 minute. currently working on some other CAS issues I may add.
