Can you explain exactly how yours was behaving with bad injectors?

I replaced my PCV again and it actually got much worse. I'm wondering if my issue could be fuel injectors or who knows what. The first time I replaced the PCV, it was instantly fixed. But the issue is back ~14k miles later. It seems there is a newer part number than the PCV I received. I'm going to try the latest version I can find. If that doesn't work, it's onto a different brand. I've had enough.... My last three rovers have all been nightmares.

 

Can you just read error codes? It could be even air filter assy/sensor that triggers misfire.

 

There is no check engine light and no codes.

 

Update on misfires. PCV and spark plugs fixed it the first time (an LR mechanic recommended I change those two things). PCV made it worse this time or more than likely it was just getting worse and changing it made no difference. Next I replaced the spark plugs. The latest part number is a Bosch plug instead of NGK. New plugs made no difference - still had misfires.

Hopeful that it wasn't injectors I ordered four ignition coils. Without any codes indicating which cylinder(s) was affected, I just replaced all four. That seems to have fixed it. I haven't been able to reproduce the issue for 100 or so miles.

Average monthly maintenance cost over 15 months (excluding regular oil changes and my labor): $256.

 

Sorry I have been away but it almost felt like it was misfiring and it was struggling to get going. I didn’t have any error codes but the app told me it was a gas delivery issue. Mine were replaced under warranty.
