My Camaro has been mis-firing badly. It idles very rough and get's a "dead miss" usually while accelerating or while climbing hills. I have already replaced the spark plugs, wires and even purchased an ignition coil. I've tried replacing each ignition coil with the new one, but it runs exactly the same each time. I've considered that the problem may be in a idle or throttled related sensor, but whatever is causing this nightmare isn't "throwing a code". Can anyone offer any ideas? I plan to put some Lucas fuel system cleaner in the tank in case any injectors have gotten dirty. Much thanks to any and all responders!

These engines are bad for intake leaks. Throttle sensors rarely go bad. Loosing any coolant?You have double checked that your wires are on the correct coil towers, right? Does it idle ok on cold start up ? If so your oxygen sensor may be bad causing a lean miss.
