[QUOTE="psufan, post: 1157292, member: 11430"] Not sure what's specifically happening on your truck; however, if the pops are occurring when you lift throttle during acceleration (i.e. lifting to coast to a stop), it's probably unburnt fuel burning (exploding) in your hot turbine/exhaust track. This is especially noticeable if you are running an aftermarket exhaust (or are catless). Both my Corvette (stock powertrain) and my Evo X (not stock / catless) do this. Most vehicles do this, but it's often well muffled by the cats and stock exhaust. Note, I would assume that this might be more prevalent with lower octane gas due to it's lower resistance to ignition. That being said, I haven't driven a vehicle that hasn't required premium in like 15 years... so no first hand experience with that. [/QUOTE]
