I have cylinder #2 misfire… replaced plugs and coil pack , with after market coil pack, still not running correct … new coil pack bad? Or do I need to replace coil pack with Mazda coil pack?
What is your question?
I had Mazda coded and it read cylinder 2 misfire, changed all plugs and #2 coil pack … still running bad… put new after market (Advanced Auto) coil pack on different cylinder and it runs worse.. do I need actual Mazda coil pack?
How long has your 2011 Mazda CX-7 had this problem?
RepairPal Certified shops can diagnose and repair your 2011 Mazda CX-7. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
First, sorry to say, but I'd never use aftermarket ignition components. Go original Mazda to eliminate any doubt.
Did you perform a base engine compression test to ensure the engine does not have some kind of internal concern?
