You are running very lean, thats why your exhaust is getting so hot. You have clogged injectors (or something else going on with your fuel delivery)or something is causing your car to lean out the fuel mixture to a extremely low rate by the sound of it.
Edit- Sorry skim read it the first time,thats it. Your MAF is telling your pcm that you have hardly any air coming in and your computer is barely pulsing the injectors.
Ok to go more indepth. The MAF uses the cooling effect of the passing air to tell how much air is passing (being sucked in). If the Wires stay too hot (voltage stays constant) the PCM assumes that there is little or no air passing and then leans out the injectors to make up for little to no air passing.
