I have a 01 Acura Cl, with about 80,000.
The check engine light came on. It had codes for random misfire, started in #1, then rotated thru all 6 cylinders.
I changed the plugs and reset.
Came back on.
I added injector cleaner, (BG, then seafoam). reset the light, It returned.
I have tried a new coil in the #1 clylinder to no avail.
What should I do next?
