I have a 2000 Chevy Silverado 1500 4.7 w/175000 mi., and it constantly has trouble starting and it idles very very low. I have to turn it over for a good 10 seconds to get it to start. It starts just fine if it has been sitting for 5 hours or overnight. I have replaced the Spark Plugs, Spark Plug Cables, Fuel Pump, Fuel Filter, and also the part of the computer that controls the power to the fuel pump because it wasnt getting any. I did not put the factory plugs in there and i have had it pluggen in to a computer and the only thing it says is that it is misfiring. What is wrong with this thing? Please Help!!!

Get an ommeter and test both the ECT and IAT here is the range chart for BOTH. These two act as your choke...
