Question about GMC Safari
P0101 is the MAF sensor and if it has even a tiny amountof crud on it, it can keep the dar from running. clean with ELECTRONICS cleaner not carb/brake spray.
P0300 is multiple misfire detected. Sound like it might need tune-up parts
P0420 is the catalyst system bank 1 low efficiency.
I would start with changing the plugs, wires, cap and rotor. And clean the MAF sensor with the proper cleaner. Then see if the car starts and idles. If it does then clear the codes. If it doesn't run right then I would suspect the MAF sensor is kaput. The P0420 code can be caused by a poorly running engine.
