Misfire
Good Day
I have an 04 civic SI with 200 000Kms,
The past little while I have been receiving a misfire in cylinders 1 and 2.
Spark plugs were changed, compression test done and coils checked by swapping to other cylinders.
CEL still comes on for 1 and 2.
Shop is talking about going wire hunting,
I don't really feel any symptoms of a misfire except perhaps for noticeable shaking at very low rpms, especially while creeping forward at an idle
Any advice is much appreciated!

Canadian SI with 1.7 engine? US SI with 2.0?
Post the freeze frame data.
I bet the EGR distribution plate/chamber needs cleaned.

You can check it out on ur spark plugs wires aswell man. My gf had a 98 ford explorer n it had misfire from the spark plug wires. I changed them n it went away. Easy way to check that is at nite time. Wait till dark. Start up ur car n open up the hood n take a carefull look at ur plug wires n if u see sparks from ur wires then u should change them. Hope that will help u out buddy. From stephen
