Hey all.

I've been trying to solve an intermittent misfire recently and I think its down to being either the afm or ignitor unit. Before everyone jumps in and says "gap your plugs", I should mention that it only misfires/stutters at light or trailing throttle between 2-3k rpm. Very wierd.

Before going to one of the bigger workshops and wasting their time, I thought I'd try to diagnose it myself. So does anyone living south of the river want to lend me a hand for an hour or so? I'd only need to salvage those 2 parts from your engine bay and test drive with them for a few minutes.

Gradenko, ive had similar issues with my car and it was also AFM, id almost say for certain thats it. I even took my car to a workshop and had them test it all via the diagnostic port, even changed the plugs thinking it was that, cost me $80 and it still didnt fix it. Diagnostics said AFM readings were within spec.

In the end i resorted to a backyard fix thinking it was the AFM, ignoring nissans diagnostics. Sure enough a drowning in contact cleaner and it was running perfectly again.

Gradenko - I'll be fitting my replacement turbo tomorrow morning so the car is already in bits. You're more than welcome to come round then and borrow the AFM for a while... PM me if you're interested...

Dsturbd, I'll take you up on your offer. Next weekend perhaps. I'll pm soon.

Went to Garage Malaga today to swap bits with cam. Found out that series 2 afm's are very different from series 1 afm's, so not much testing was done. Did clean the afm with contact cleaner though, but that made no difference (thanks anyway, red17).

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
