ya i just changed my thermo stat today got everything changed put back together and started the truck had a high pitch tick( its not valve or rod kinda tick) more like a zapping kinda sound ticking hard to explain...and wen i reved it to about 2 1/2 3 thousand rpms and let off the gas it would fall back down to like 200 rpms and about die>>>.any body got any ideas that would be sweet

 

Check all plug wires and grounds. Might try looking around with it running (be carefull) at night to see if you see any arching from the plug wires.

 

i didnt see any arching but i dont understand why it would all of a sudden start making this noise and about stall after a rev

 

I was thinking that maybe a wire got knocked loose somehow when you were working on it and the "ticking" was arching.

Did you unhook or remove anything to do the stat? If so, double check everything you touched. Make sure it's all tight, clipped, snapped, etc.

 

well first thing i did before i worked on it was put a magnet down inside my Tb to see if it had the stock plenum thing witch it does but its not broke yet...ten started to replace the stat the only thing i took off was the airbox

 

Check the connections for the TPS (driver side of TB) and IAC (rear). Make sure they're plugged in and making contact. Try wiggling them around a bit, see if that helps. Might have bumped one or both and lost connection between harness and sensor.

 

Ill try its wierd bc i took it down the road and there was no loss of power or anything

 

Spill any coolant on the belt?

 

possibly would that effect anything
