Last week i had my plenum gasket replaced, I get my truck back and everything works great. I have probably driven approximately 200 miles since the repair, and now i am developing a sputter when trying to accelerate (especially when driving in lower RPMs 1000-1800). When i drive the truck cold, it runs perfectly fine with no sputtering issues at all. The longer i drive it, the worse it gets. Once it is warmed up it starts to sputter when the truck is idling. Again, when the vehicle is cold i have no problems.

Last night the check engine light came on, from doing research I believe i cannot check the CEL code without taking it too a shop(b/c its a 98'), please confirm that. I am going to get the CEL code checked out, and i am assuming that is the problem. I am looking for any advice so I can decide if it is someting i can fix myself, or i have to pay a mechanic. ... Thanks a lot

 

you can take it to autozone and they'll check it for free. since it only happens when the truck warms up, it could be a sensor... like the o2 sensor.

 

They will check it for free? I wasn't aware of that, thanks! I will take it to the local autozone. How hard is it to change an O2 sensor?

 

Is that what it is doing then go to tips and tricks for rams in the SEC. GEN RAM INFORMATION thread.

 

i'm not saying that its definately your o2. but they'll check it for ya. they can be kinda hard to change sometimes because they'll rust into the exhuast pipe. if it is your problem, get some penetrating fluid, some antiseize, and a new o2. spray the penetraating fluid on there and let it sit for a while and go at it with a wrench. when it comes out you put antiseize on the new o2 threads so that it isnt so hard to get it off next time. people say that you can spraythe old one with fuel injector cleaner to clean it off, but if its shot im not sure thats the best route to take.

take the first step and get the code read... take it from there.
