I have a 2001 Dodge ram 4X4 360 motor. I am having problems with it. If I am driving around and let off of the gas it starts bucking. It does not do it all the time, it idels and runs fine under a load. It had a tune up about 35000 milea ago I got the expensive plugs with a ten year waranty also got lifetime wires and cap and rotor. Any sugestions |

bucking under deceleration is almost always a too lean condition. (does it actually backfire?) timing might be too far advanced (or lost its vacuum advance) or the Throttle body is getting hung up and closing too early It is kicking any codes out? I'ts almost definately an electrical/throttle issue. |
