Truck starts to stutter when trying to accelerate in low RMP range. This usually happens when truck is in overdrive and/or when RPM's are 1500 or less. Truck has always been sensitive to poor quality gas so I use Lucas fuel treatment but that doesn't seem to help any more. The strange thing is this doesn't happen all the time. The truck has its good days and bad but it seems to do worse after hitting some bumps and shaking up all the crap in the fuel tank. Any ideas? Thanks in advance.

When as the last tune up? Has the fuel filter been replaced reciently? Have you checked fuel pump pressure?

Thanks for the reply. Since my last post I have replaced my spark plugs with Bosch Double Platinum plugs and it is running alot better but it does still stutter at times when trying to accelerate at low RPM's, usually while in overdrive. Any suggestions for the next thing to check would be appreciated.
