Heres the dish i just swapped another 22re into my truck, got my hands on a timing light and tried to tune it in, the mark on the crank sheave shows up completly off the timing rack by quite alot. I know its supposed to be set at 5*BTDC when the motor is idling at 800rpm in "limp/diagnostic mode" but when i try to trip out the plug with a wire nothing happens, nothing changes and the motor continues to idle at about 1050 rpm. Any ideas why the diagnostic port isn't working or maybe someone knows what to time the motor into at 1050 rpm? The truck currently starts and runs but when i let off the throttle it continues to rev for a second then comes down.

landed some info off a guy on another forum, i guess when your jumper doesn't work its a sign that your tps isn't functioning properly, i need to down my idle speed to around 800rpm and the base timing with no jumper is 12*BTDC. He also gave me this link http://www.4crawler.com/4x4/CheapTri...roubleshooting

If you can't get the mark anywhere near where it should be, you may have a timing chain off a tooth. You'll have to pull the valve cover to check if it comes to that...

I did the chain before i put this motor in and i'm confident its in properly, this motor actually runs better than my last one, more power, better compression (sorta haha) but the last motor had 450,000km's so i'm not going to knock it to loudly
