someone tell me what i did wrong i changed the lifters the timimng chain head gasket now it wont start if i crank over and over and hold the pedal to the floor it my start then when i release the pedal it dies did i forget something??????????????

It sounds like the IAC Valve mightnot be working. The IAC Valve opens to allow air past the throttle plates into the engine, to allow the engine to idle.

Adjust the pintle on the IAC Valve, to do this, with the battery disconnected it removed from the Throttle Body, push in a hold the spring loaded sleeve, then turn the pintl/tip of the valve clockwise to move it in about an 1/8", then put it back in the TB, connect the electrical connector and reconnect the battery.

i done that it starts now but when it warms up it quits running also the exaughst header is getting red hot

Your timing is off, set the #1 Cylinder at TDC on the compression stroke and check the timing marks on the Crank and Cam Shafts.

Yea but if you set the timing and it still dosent work, could it be the Camshaft Posision sensor because doesn't that correlate with the crankshaft sensor to set the timming on the other pistons.

The Crank and Cam Sensors corrolate to adjust the timing between the Fuel Injectors and Ignition Coil (Spark), not actual engine timing.

ok guys i did everything you said and it runs great you guys are the best thanks for all the help
