CEL Misfire
I have a solid CEL. It happened when I start up the car and it idles for 3 to 4 minutes. I took it to a mechanic on base and they pulled up the CEL code: P0300, P0301, and P0302. These codes are Random/Multiple misfire, misfire in cylinder 1 and 2.
So what they did was replace the sparks plugs with Bosch Platinum and reset the timing. Later that day my check engine light still came on again.
I don't know whats going on. Stressing my out!
HOW CAN THIS PROBLEM BE FIXED?
THANKS.

First, is there ANY warranty coverage left? If you can find if any previous maintenance in that area (cel)? Ask dealer to pull history of car?
While my story may be different, I also cleared codes, once, once they
went away on own. Never had flashing cel (apparently very bad from forums).
I have 78K miles, bought certified fm dealer at 68k miles. I put in Bosch plugs 8000 miles ago.
Recent checks, I found I DID NOT properly tighten, they loosened up, bought torque wrench and tightened properly - original plugs I saved.
( I noted when I pulled plugs 1 and 4 did not look normal color. )
I went fm cel to stall at lite, clutch in.
Took to dealer and diagnosis said poor compression in cyl 1 and 4.
Waiting for them to get approval to replace head (?complete) for "bad 1 and 4 exhaust valves."
I am repeating phone conversations with dlr, I will find out shortly if all approved by "Honda care", and report back. HTH

i took it back to the mechanic on base and they pulled up the code again and now it's only P0302....
they said it couldn't be the coil packs because they switch 4 to 1 and 3 to 2 so they were working.... they suggested that i should get my valve adjusted...
so im still taking my car to the dealer on monday and find out whats going on.
the car is a stock 2000 with absolutely no mods.

Bosch Platinum is a no no
You should stick with the NGK's. I read some pretty scary stories on here about the Bosch plugs.
