So as promised I did venture into that dank and decrepit place, full of horrors and treasures alike, seeking to put things right. I didn't have Deckard Cain to offer advice and my tools didn't offer any defense bonus to slashing or blunt damage.
This place is thick with the stench of ghoulsI'm talking of my garage of course, and I was attempting to fix the skyline.
The first thing I had to do was remove the oil cooler lines as I had stolen the cooler for the gemini and the upgraded one I had bought has different fittings. I don't know how I fitted the cooler and more specifically the adapter (which attaches to the block and has 2 braided oil lines coming from it) in the first place, but removing it was not fun. For a start its like trying to do heart surgery by putting your hand up through the urethra of your patient. Its seriously that tight in there, at least on that side of the engine. I'm used to standing in engine bays kicking shit into place rather than half squatting at the side trying to undo oil lines with an inappropriate tool. The second thing is that because of the location and the condition of oil lines themselves my wrists ended up looking like they belong to a fan of The Cure who just ran out of eye liner.
Eventually I managed to remove the oil cooler (and most of the epidermis on my forearm) which made it a lot easier to get the fuel filter out. The fuel line to it for some reason had disintergrated. Perhaps it was the wrong type of hose, or the ethanol in the fuel, I'm not sure. It sure made a mess though. Combined with the oil lost from pulling off the oil cooler and adapter plate the floor of the garage looked more like Prince William Sound without the sea birds... uh, so exactly like Prince William Sound.
With the causing an ecological disaster part of the job out of the way and the garage now smelling like Aurukun on a tuesday afternoon, I pulled off the TPS, AAC valve and AFM and cleaned them all with the closest thing I had to electrical contact cleaner. Threw it all back together and tested voltages with what they should be. Throttle sensor I compared with what it says in the service manual and it was about right (0.5V) and it seemed nice and linear when you planted it. No dramas there. AFM it gets a bit tricky as its a Z32 one which results in me having to compare voltages with the (bunch of) retards over at the Skylines Australia forums. No short circuits or other nonsense there. Another 0.5V which is about right too.
Kicked it in the guts - it started - idled a bit rough but better than last time I turned the key. Voltages for AFM was about 1.1V at idle which sounds about right. Bit more revs and it started to die as it had before. Leaning out. AFM was getting 1.6-1.8 or so volts at 2-3 grand. Based on what the SAU guys said when they weren't rubbing cocks together (those that still have them) that's a bit low. Seems to have a big flat spot at 3 grand with no load. It sounds to me like its going massively lean. It actually feels something like its hitting the limiter, and watching duty cycles the injectors do seem to switch off at times, but TPS is reading ok voltages and not shorting. So I'm really confused. Even so, testing voltages beats the shit out of working on carbies.
Gave the AFM another big dose of carby cleaner trying to hose the element as much as possible. I'm running one of those useless oiled K&N pod air filters which probably fouled up the elements. After it tried off I took it for a strap down the road, ran beautiful for about 30 metres then shat itself, started missing and backfiring but I had a brief moment of wa-cha-cha. (I was half expecting to see the Red and Blues appear behind me.) Then it stalled. Got it back to the garage and parked it. So I think its a fucked AFM now, or at least I hope it is. I'll try clean it up properly (by removing the mesh and getting a brush on it) and I'll see if i can borrow one to test in isolation.
Its a bit of a disappointment, but I really should have realised that it wasn't suddenly just going to fix itself by sitting idle for 3 months or with half a can of carby cleaner.
Fuck cars.

Apologies for the Aurukun joke, that was in poor taste. Much like a glass of Optimax, I'd imagine.
