All 6 cyl missfire with multiple codes. Idle is rough and loosing the torque power.
Just completed scanning process on 2003 6 cyl with 118K miles on her.We exctracted muliple codes:
238, 240, 239, 202, 203,228,227,241,242,243.
All cylinders missfire indicated on the scanner.
Sounds like a cat converter? But before I wanted to get in touch with everybody within our community and ask what do you think.
What else could it be?
Car rides noticeably different then before. Power is not the same but still going 60-80 with some hesitation.
I could feel when in park or idle engine missfire.
I took some screenshots and will upload them shortly.
Thank you!

well... misfires (if there are real ones) - start with plugs, then coils... if plugs were not replaced within last 50Km miles, they can be replaced as a preventative maintenance, regardless if they are culprit or not... if the coils were not replaced within the last 100K, they can also be replaced under the preventative maintanance... if those things do not resolve the misfire, then the wiring to the coils... then, the DME...

what about those screenshots? you got them?

Yes. As I promised the screenshots are posted. I took two screenshots because display on the scanner could not fit all the codes. Please take a look.
Thanks again!

Here they are. Sorry, the images were too big to upload. Took a few minutes to resize.

Ok, I bought NKG plugs. Will replace them today or tomorrow. I will post the result.
Thanks again

Based on the fact that all cylinders are reporting misfire, this sounds like a massive vacuum leak to me. I'd check for any loose hoses, especially near the intake, and do a smoke test if you haven't already. How many miles are on your X?
