So Ive been fixing things left and right on this car, and theres still more to do.
....its a 90 2+2
First off, Fuel leak, only when over half a tank... its coming from the filler neck, where it meets the tank, there is an Oring there that seals it, WELLLLL...I replaced the Oring, also keep in mind nothing is bent. It still leaked, so I took it off again and bought some MOTOSEAL, and I even made a gasket for it and soaked it in the sealant, and it STILL leaked....just not as bad. I just dont know what to do any more.

Also the high idle. Its not really that high but its higher than it should be, Ive already set the timing, 15* btdc, and set the TPS correctly, and the adjustment screw is all the way down, did everything at OPT temp. It usually sits about 1k fully warmed up, when I come to stop light or cruising then put it in natural it will jump up to 1500-2k then slowly come down within 10 seconds or so.

So any suggestions would be greatly appreciated....
