Hey guys i have an issue that i have been trying to troubleshoot for a while and its pissing me off! My car is a higher mileage 5 speed ka 209,5xx miles. will start right up and has plenty of power, but on deceleration while im still in gear, it will backfire kind of loud. i dont have a muffler at all and after the cat, its just 3 in straight pipe. now the one that really bugs me is the hesitation... it hesitates when i try to maintain speed... it doesnt really do it when i accelerate, sometimes at the start of acceleration, but as long as i accelerate, it doesnt hesitate. i have no idea what it could be and it bugs me. i have already replaced spark plugs, cleaned my points, plugged a few vacuum leaks, adjusted my distributor, and replaced my fuel filter. oh and tried adjusting my IAC valve because i figured maybe it was off as well, but no luck. any info will be helpful. thanks
