This morning I started up my truck and let it run awhile. Then I sarted going down the driveway ( 1/2 mile long ) and the truck sarted surging with me holding the gas peddle steady at about 10 MPH. Does anybody have any idea why it's doing this? It's probably just because it's cold, but I'd like to be sure because little problems can become big problems quick.

 

Mine started doing the same thing after I installed the 14" round filter, just until it warms up a little though, then its fine. Also had a surge issue when I bought mine where it would surge at hwy speed, but only on cruise, not foot. It was the TPS that time. Your probably right in thinking its just because its not warmed up. Did it just start doing this lately? Maybe take off the IAC solenoid from the rear of the TB and give it a cleaning. This helped my surge a little.

 

don't know if this will help but I just read this article before reading yours.
