Throwing cylinder 1, 3, and 5 misfire codes, has ticking noise that almost sounds like an exhaust leak. Other codes include system to lean bank 1 and 2, O2 sensor bank 1 and 2, and misfire detected with low fuel. car will run fine at times and other times it will hano power on acceleration and compulsive shaking. While coasting on higher speeds the rpms will skyrocket while set on cruise. Shifting hard and at high rpms. Fuel pressure test was fine and fuel injectors tested fine. All new spark plugs and getting ready to replace coil packs. Spark resistance test showed extremely low, could this be an issue with the ecu? Plugged up Catalytic converter? I am completely dumbfounded by this...Anybody else have these similar issues? What was the outcome? I have a video of what noise it's making...only has 80,000 miles on it and did not start acting like this til I started it and drove it when it was -20 degree weather outside.
