So, posted here before, but I've since tried a few things and eliminated others.
Basic symptoms:
* No low end power at all... WOT doesn't do anything until higher RPMs and even then not much. Once it starts boosting, I get a fair amount of power, but nothing like what I should be getting.
* 3000 RPM-ish and 5500 RPM-ish create a really weird vibration harmonic where if i hold it near those RPMs, it hums and vibrates strongly until I move above or below that area (+/- 200RPM or so.)
* Ticking noise when I give it more gas. It can hold RPMs in place with no ticking, but when I give it more gas you can hear the ticking. Hence, it might be exhaust, it might be valve tick, but at idle and holding an RPM in place, no tick can be heard, leading me to believe it wouldn't be valve tick.
Things we've tried:
* Re-did timing from scratch a few times. Incredibly carefully set TDC on the crankshaft pulley, then TDC on the two cams, attached belt. Felt same exact as before. Took the belt off the cams, rotated crankshaft 360 degrees (same thing as cams by 180) and put it back on. Absolutely no difference.
* Pulled ignition wires off one at a time and tried running the car to see if a single cylinder was busted (ran on 3 cylinders each time, different removed wire each time.) Each time, the car idled far worse, and had way more trouble revving. No one cylinder had any greater effect than another.
Possible ideas:
* Is there anything else to do with the timing? Could valve clearance possibly be causing this? Stuck valves or anything like that? Could the TDC nubs on the cams under the valve cover be wrong or something? Anything we should try with timing like moving the cams 90 degrees different or anything like that? Moving it one tooth off from what looks right maybe?
* The car was sitting around for something like 18 months before running again. What could go wrong like that?
* The gas was crappy. The tank was nearly empty, and when I filled it up with new 92 gas and drove around for another 5-10 minutes, it got noticeably better. Could the fuel filter possibly be clogged or something due to the crappy gas or something? Should I flush the tank from scratch to eliminate all remnants? Would having 80% new gas and 20% old gas in there possibly be causing this? What if the old gas was 87?
* I put in NGK Iridium spark plugs, at the gap level they came at, and switched to ignition wires from the MR2 3S-GTE I have lying around. Could the iridiums possibly be doing anything bad or possibly the other ignition wires? I can't imagine they would, but I'm getting desperate for ideas at this point. I haven't tried switching to the old plugs or wires yet, but I'm considering it. It just doesn't seem like it could have anything to do with it.
