? on Trouble Codes

41 Ignition Control (IC) circuit (open circuit)
42 Ignition Control (IC) circuit (shorted or grounded circuit

what could these 2 indicate??? any ideas???


48 Mass Air Flow (MAF) sensor circuit
I replaced the MAF after a N20 backfire, and it still throws the code....but seems to work without a flaw

i also had a PCM Prom Error, but forgot the number of the code
no clue what that means



need some help, any would be greatly appreciated. Thanks.

also SHOEBOX, thanks for your website man....any input u have would be great.
