Hi axeman
I have 2001 sportage ex also a problem that hopefully you've heard of before. cel on.
1.Gas smell when cold outside and inside pass. compartment.
2.New prob. just started last wk. Car starts ok seems to idle fine but when given gas hear a pop or backfire from engine. hesitates when trying to take off. went to autozone codes are 0128 and 0303. Have to get inspect sticker by 1/31/07. with this new hesitation problem, when riding down street, cel flashes about 1x per sec for 5 or 6 flashes then remains steady on. thanks
