MISFIRE
 

MY 02 dodge v6 back fires through the throttlebody ,checked timing,wires,dist,cam,cat,crank censor,computer,valve springs.all ok amy one else have this problem ?

You may have a intake manifold "belly pan gasket" leak. How many miles on this engine?

Check engine light is on? What cylinder is the misfire on? Perform a leak down check on that cylinder.
