I think the timing is off. The engine starts and and it won't really idle. It revs up to about 3000rpm then dies. I check all the hoses and I don't see any obvious problems. I assume its the timing. I adjusted the block to tdc and then head to the have the valves closed on the #1 cylinder. help...

Check the TPS? throttle position sensor.

What should I look for with the tps? should I test with a volt meter?

-The ICV might be bad
-the voltage could be off
-TPS switch as mentioned above.

Theres one more thing it could be, but I forget what it is.
