Gentlemen I'm at my wits end here, any help or direction would be extremely appriciated, willing to investigate anything/everything.
I purchased a '92 SC400 a few months ago, car looked good, ran okay and was generally clean. First things first, I did a full tuneup (caps/rotors/plugs/wires/fuel filter/air filter.) The car ran great, strong, no CELs. No problems. On go the 19's, Konis, Pro kits, Recaros, etc. I'm happy.
About 4 weeks ago a buddy asks to borrow the car to run errands as he sold his to go work in the UK for a year. No problems, trustworthy guy, etc. Well in the first 15 minutes he sideswipes a GMC Safari at about 30 kmph, pushing in my passenger fender, bending the rim, and scraping the door. He said he stopped, exchanged info and then as he was pulling away (fender cutting my new rubber) the car just died. He started it up and drove a few feet and it died again. Had the car towed to another buddy's shop.
So, I show up the next day, crank it a few times and it will start, but the idle is crap, lots of misfires, low idle and very slow to rev, only revs to 1800, won't go anywhere in drive, stalls right away. A quick look around and notice there's next to no gas in it. Great. So I go get gas, throw in 25l and no change.
I did a few hours of reading here and the AFM looks suspect. I unplug the AFM and the idle smooths out, but not much, maybe 50% better. At this point I go get a used AFM, plug it in, no change. I figure I probably got a bad one and order one from the States. Three weeks later I get the AFM, stoked I can drive again, plug it in, same issue.
One thing I did notice was that the car ran only slightly better with the AFM unplugged, others advise the car runs fine without, albeit a little rich. Does not drive well at all without it either, won't rev up accelerates with much trouble, getting to 40 kmph is impossible.
I did check for spark and fuel pressure is good. I tried a spare ECU that was working well in the previous car. Also tried both ignition coils. No changes here. I also tried pulling codes, all I got was 29 for a bad sub O2 sensor, I replaced both, no solutions here. No other codes in memory, but that 29 still pops up after a reset. When I took the fender off, I looked for any damage to wiring, didn't see any. Didn't see any unplugged/broken connectors either.
If you've read all of this, thanks again, and please HELP MEEEE!! I've posted on other sites that I frequent but no help available it seems. If anybody is wondering why I don't just go through insurance, the reason is that the other driver apparently didn't care about a new dent in work van and didn't want the hassles. So I hear at least.
