My 2005 Accord EX 6-cyl 6 speed manual trans engine light came on today while on the highway (after driving and stopping for a while, then back on hwy). I checked the gas cap per the owner manual and filled up after the light came on...no problem there. I have had some trouble with the car turning over after days of sitting idle. Its not a quick start like normal. I've had the battery checked twice at Advance auto and its putting out enough amps (still original battery). I thought for sure the battery was at the end of its life, but both times it checked out strong.

Any thoughts what it could be? I get the oil changed routinely, though I recently moved and have not been to a local dealership yet (my old one was great and took care of a lot of warranty work for me..transmission 3rd gear fix and trim work). I thought it could be bad gas, but it ran fine til the end of the tank.

I read something about valve clearance or catalytic on one of these forums doing a search, but I don't know anything about that. The auto store guy thought I could have a bad ground or something (just guesssing) in regards to the starting problem. The alternator and starter checked out ok on the diagnostic too.

Thanks in advance. I am very curious if the two issues are related. I've had the starting issue for a few weeks prior to today (engine check light).

 

Stop by autozone and have them scan for code(s) on your computer. Post the code(s) on here. They will start with the letter P and have 4 numbers, like P1234.

 

Test today said Random misfirings on cylinders 1 & 5. Just replace them all?

 

Could you tell me the actual code number?

 

I didnt' get them, but sounds like it was a TSB and I can get a software update. Doesn't seem like anything seriously, thankfully
