thwup thwup thwup... what's wrong?
When I start my truck it sounds like it's hitting on 2 cylinders... thwup thwup thwup. I give it throttle and it eventually smoothes out and runs normal. Once it smoothes out it runs just fine. TPS? Throttle body? Something else?
Thanks for any suggestions!

I'd guess you have a bad spark plug, but I'd do a compression test, pull all the plugs, and also check the injectors. Start from there and let us know what you get...

How is your coolant level?
If you're losing small amounts of coolant, it may be a bad head gasket allowing coolant to leak into a combustion chamber after the truck is shut off.
