well my heater hose busted and to needed to change it, i couldnt get to the hose so i had to take off the distributor. when i put it back on it ran fien for a couple of days and now its starts to misfire really bad and throwing out a random misfire code. i tried to fix the timing and put it on the tdc mark and still misfiring. it also starts really rough, backfires from the throttle and idles at like 400..any help would be appreciated....
