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!

Adam,

the next thing i would test is for fuel/fuel injector....

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.

SI in canada is the same as EX in USA.

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

Duh, shoulda noticed the KM.

If the freeze frame says it set the code while driving, not stopped and idling, then I bet the EGR plate needs cleaned out.

these cars do not have spark plug wires
