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).

      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

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
