Hello friends, i have a 2007 Crv and its making me go crazy. It first started with a misfire 4, change all plugs with NGK Iridiums. Code went away then a few days later misfire codes for 3 and 4 and multiple random. Replaced ignition coils with OEMs. Didnt change code but then i started to get sputtering while on load, on idle cars is amazing, no smoke and no burning oil. Then i decided to replace injectors cause the codes for misfire where still active and while on load CEL while start flashing then go away and sputters during load. Codes then went to 1 and 4 or 2,3 and 4 misfires. Replaced vvti solenoid and injectors OEM. Nothing change. Then i got a code for Cam position sensor A, replaced both intake and exhaust sensors, not oem got those at Oriellys. Still same issue misfires and sputters at load and sometimes baby backfires. Someone told me possible Cam Phaser. Any advice lol or help?
