My 2001 2500 v8 has an on going issue where it bucks/jerks while driving but only for the first 5 min upon start up. The Plugs and wires have been replaced and some temp sensors. There is no Engine light on or codes for that matter. And once the truck warms up it runs fine. Just Looking for any advice or suggestions.

 

test your fuel pressure, it may be the fuel pump on its way out. how is your idle if you tap on the gas and let off right after you start it. it should drop down to about 900ish when its cold.

 

Check and or clean or replace the TPS, and IAC. It sounds like a similar problem I had with my 99 2500, and my current 01 1500. Replace the 02 Sensors. Cured the problem on both of them.
