i did that...

Well...like I said. Many times before I have ran into the same issues getting the car into timing mode. I do believe if you just rev the car to 4k and hold it there for about 5 seconds and back to idle and back to 4k and do this 3 times. Which keeps the crank steady with the needle for a good reading. Works everytime now. FSM or not...unplugging the tps doesn't always work. But try both ways...and see the differance.

You did say you're timing is at 10degrees. Is this a ga16 or an sr20. IIRC 15 degrees is OEM factory setting not 10.

So even unplugging the tps doesn't necessarly let it go into timing mode?

Not in my case....but I'm sure someone will argue it. But I can tell you that with mine in timing mode done multiple times both on a 1999 emissions over loaded de and now ve I had the same exact problem no matter how hard I tried and ended just setting it with the tps plugged in. Set it at 18 degrees no problem and the car woke up like hell. No issues.

When I did mine. The tps was un plugged but instead of revin. For a sec. It stayed reved

Im about to say fuck it and swap out my ga for an sr.

Ok.... so this IS a ga and not an sr. Are you sure that the timing is 10* on that motor?

yes i had it checked at a friends shop
