P0305.. cyl 5 misfire.

It happend under boost I got the blinking CEl and started running like crap. I backed off quick and CEL went off, smoothed out.

Should I just change the plugs and clear it out (code) or should I just take it to the dealer?

 

just curious- how many miles do you have on your car? I just had my ecu flashed and car has 25k mi and original plugs. I haven't had any problems yet, but i'm wondering if i should change my plugs before 30k miles.

change the cylinder 5 coil pack( right side of engine facing it middle coil). I bet that fixes yoru issue. GL

PS go to a shop with a guy with small hands. You will not have to take everything off to get to this coilpack.

 

40k on the car.Plugs were changed (to oem spec) at 32k.

 

ok cool. Will give it a shot.

The blinking said drive car to repair shop.... Is it ok to drive it?

 

aboslutely just dont get on boost or itll break up. I blew a coilpack and go the same code. Cross your fingers but Im pretty positive this will fix your issue. If you want to go a step further replace all your coilpacks and plugs but I think your fine.

if you replace the plugs upgrade to ............. sorry have forgotten some chimein with plug no..

 

You go from 5 plugs (colder) to #6 hotter.

That was my problem. I have since replaced all coil packs as a preventative
measure.
