That sucks. after the light and chime sequence Does the backfire happen just once with the first press of the accelerator, or backfire with every punch afterwards of the accelerator? I'm assuming no codes?
Hope it's something simple.
Light and chime came later... backfire comes most of the time... at idle you can hear it sputter... up front the engine sounds smooth... I'm thinking catalytic.
So I got a misfire on cylinder#2 he's thinking it may be a clogged injector, as everything on the surface looks fine... I'll find out Monday... sucks I don't have the Jeep all weekend.
