What’s up guys. Had a check engine light come out about a week ago. Came up as P0174-bank 2 too lean. Car seemed to be running perfectly. Cleared it and off I went. Yesterday I got the check engine light again. This time the P0174 code is not there. But I got 4 others. Any help or info is greatly appreciated.







P0301- cylinder 1misfire detected.

P1313- misfire catalyst damage bank 1.

P1316- misfire rate above limit.

P1000- ?

 

I think all the codes stem from the P0301. Could be coil wiring, coil, or faulty spark plug. Could be Fuel injector not spraying correctly or at all. And if it were compression in that cylinder, you would have a bigger issue to worry about.

 

Just incase you needed reference.

 

NYCJAG, the P1000 is an "ignorable code" (ie, it is just telling you that you are not meeting all the conditions to be error free. As was stated, alll your problems are stemming from the P0301 code. Could be a simple bit of oil in the #1 plug well. Could have a plug that has failed. Could have a coil that is going. Could even have a fuel injector that is giving up the ghost. Granted, of the options, the coil is the more likely suspect. I would say to access plug well #1 and make sure you don't have oil in it, swap coils #1 and #2, and then pull plug #1 to see what it looks like (if it looks fine, put back in, if not, replace). From here, if you get a P0302 code, you know the coil is bad. If the problem stays with cylinder #1, then your fuel injector needs replaced.

 

Thermo's post years ago, also IF...IF there is any possibility that you got water on engine (like doing the donk cleaning engine with hose/car wash thing) it will cause a cylinder fault. Granted this is usually multiple cylinders but...




lmao! He's quicker on the draw than I.
