Help! any one out there have any experience with the problem I'm having?, I have a 2000 V10 2500 Manual Transmission. My problem is when I'm driving slow like 25 miles an hour my truck bucks like crazy, I keep telling myself its just thirsty for more Gas because as soon as I step on the gas problem solved. It runs great out on the freeway when Im on the gas but does buck a little when I let of the gas. Ive noticed that its even worse now that the temps have gone up, I never noticed to much in the winter unless I warm the truck up before driving. Ive read several things on the internet but many different Ideas of whats wrong I want to fix the main issue, and don't want to spend a ton of money trying to resolve this.
Any Ideas would be greatly helpful.

 

Welcome to DF.

What RPM are you running at low speeds? (what gear ya in?) Getting any codes?

 

I'm usually in 3rd and at 1500 rpm, just yesterday I bought sea foam and it seamed to cure the problem about 90% I barley notice it might have something to d9 with not getting enough fuel, dirty injectors maybe. But im not sure why it would do it more in higher temps.

 

Higher temp means hotter air, which alters how fuel atomizes. (yeah, its a lotta fun...) Also, PCM goes into closed loop.. (starts paying attention to O2 sensor) If the O2 sensor is old, probably wouldn't hurt to replace it.
