Hello again,

I have been having a problem with hesitation / bucking at a constant speed when more gas is applied as well as taking off from a stop. Now I am hearing a sort of farting noise from the exaust. The exaust noise just started happening recently but the hesitation has been around for a while.

I have replaced plugs and wires, replaced fuel filter, cleaned the MAF, replaced EGR valve and DPFE, replaced IAC valve and am out of ideas.

I am hoping that this new exaust thing can shine some light on the problem. I am NOT getting a CEL

Thanks for any help!!
