Multiple cylinder misfire loss of fuel pressure

Sounds Good ! Good luck with those plugs. Hopefully they've been replaced before. But it'll be running like new again when you're done ! But do use a 10w-30 or 10w-40 synthetic oil in the motor. That 5w-20 oil from the factory is just for gas mileage numbers, but it will lead to pre-mature wear and damage later for the owner to deal with.

So I got the plugs, coils, and injectors all replaced. Plugs came right out, no problem. Now It starts right up but I instantly got 2 new codes p2195 and p2198.
02 bank 1 sensor 1 stuck on rich
02 bank 2 sensor 1 stuck on lean

Anyone have any ideas what to do next? Could this be my catalytic converters? I read that they might have been ruined with all the raw gas out of the cylinder with the stuck injector.

Look for any vacuum tubes and hoses left disconnected. Especially in the areas above the valve covers. The PCV hose(s) are typical culprits.

I have triple checked the vacuum hoses and everything is hooked up.

Any abnormal running condition or just the codes set? If no running issue clear codes and drive see if reset. Possibly could’ve set from all the excess fuel from before you repaired.

Also use some carb cleaner with engine running and check for vacuum leak.

It was running a little rough at first. I just change the oil (it smelled like straight gas). And now it seems to run a little better. Cleared the codes and drove around about 10 miles. Don't have any codes showing now. But my scanner is saying the following system monitors are abnormal. Cat. Eva. O2. Htr.

I can look at the live data but really don't know how to interpret it.

You’ll have to keep driving for it to complete all drive cycles. If is running ok and no engine light on I’d say you good

Fuel in the oil kinda worries me if it was enough to whiff it.

It takes 40 drive cycles to clear a code. What I have done in the past is to disconnect the vehicle's battery for an hour or so, then start it again. When you start it,the tach, speedometer and gauges will go all the way over and pin, then go to nothing then they will all read normal, This says the codes are cleared.

Another issue which can occur. The in-tank fuel pump has a screen in the intake port. If it gets crap on it, the fuel flow goes bananas. If it runs rough or refuses to start, smack the fuel tank bottom a few times. If it starts, take the fuel pump out and clean the screen. Happened to me on another car I had.
