Am having a problem with low end, engine breaking up, slight backfire, 700 to 2500 rpm. Believe it is due to bad sensor as have replaced many crank sensors on other vehicles acting in similar nature. Any one with info on the subject. It is DOHC. Should I be looking at another sensor. I replaced timing belt @ 5000 miles ago. Plugs, fuel filter, etc, all new. 82,000 on engine. Thanks
