Keep getting P1150 DTC after putting on Magnaflow catalytic converter. Started with an Ignition coil problem on Cyl #3. Replaced all coils and plugs (183K miles). Next DTC was P0420 - catalytic converter. Made sense since there's been a slight power loss over the years. Figured bigger might be better = Magnaflow. Replaced A/F on Bank 1 upstream because old sensors threads were stripped.
Replaced A/F sensor for Bank 2 Upstream but it didn't clear code, so I'm doubting sensor was even defective.
Has anybody had to have the ECM (ECU) reflashed after putting on a larger exhaust? Car was driven ~ 30 miles with ignition coil defect, so no saying what fuel injector looks like.
