The p0036 p0056 p0141 are all o2 sensor codes. Code p0102 is a mass air flow sensor code.P0451 is the evap pressure sensor code. The p2122 is accelerator pedal sensor 1 low voltage. So what do you mean the cats gone?As far as the codes go I would be looking at the code p2122 that put the vechile in reduced performance mode where the timing is retarded etc. Thats what happens when there is a fault in the throttle by wire system its a safety feature. Your going to need a scan tool that can read Live data and the throttle position sensor readings to diagnose the problem. The top fix for that code is the gas pedal assembly replacement but no guarantee that will fix that code.
