Engine began shaking a lot. After I was able to look into it I got a p0302 cylinder 2 misfire. I swapped out all the spark plugs which did not help then after playing for a minute with the wires determined it was the coils. Swapped out the coils and it got rid of the 302 but replaced it with a 300. It doesn't run as rough but there is some roughness to it. So I wasn't sure but I decided to disconnect the battery to reset the computer just in case the computer was making it run rough because it didn't know it was fixed. Wife drove it to work a d back and I checked the codes again. 300 was gone. Now I have p2097. Could any of the above caused the 2097 code. I know its an o2 sensor but before I begin swapping parts and emptying my wallet, I would like to know if something else is causing the problems. Secondly, while my wife was driving she said "gas cap" came up on the display. I've never seen that before and was wondering if it could be and how related to the 2097 code and/or the replacement of the coil.
have the same problem?
