The engine code i got for this problem was p0301 cylinder 1 misfire. I replaced the spark plugs and wires. it was fine at first but now its missing again but only at idle. Also the transmission is having some issues. It does fine when its cold or at low speeds. Then it revs up until almost redline then still doesnt shift. It acts like it doesnt know when to shift or something. I replaced the Transmission output sensor and that didnt fix it. Sometimes the transmission does this and at other times it doesnt. Please could someone help me with this. Could this be a vacuum issue and or a bad injector. I need to know the next steps to take
