Re: 07 runs bad when at red light
Maybe you got some bad gas ?or someone put something in your gas tank
Put in some dry gas/fuel injector cleaner run it low and fill up at
at a different station and see what happens.
Cloged fuel filter/injector or air cleaner
Bometimes the throtle body flap om the intake gets a carbon build up(theres a pin hole that gives air at idle when flap is closed,sqwert some spray fuel injector cleaner in and around the area.
Bad plug or wire(i would think they would cause a code to come up))
All cheap maintenance type things to check and do they couldnt hurt
