ECM screwed?
OK, My car has been running really good. Well , not any more.
It won't even idle anymore. I pulled 2 codes a 33 and a 42 and with the laptop hooked up to it my TPS sensor is around 2 volts at closed throttle. All this came about at ounce. All my friends are stumped as well. Any ideas guys?

I'm not exactly sure, but shouldn't the TPS voltage at close throttle be around .54, 2 seems a little high to me. This may be the start of your problem, not sure though.
