<1K on the car and it took me 3 times to start it today. Now, (unless it's just me) the idle seems rough. There is a noticeable vibration coming through my feet and my seat. It's not much, but it's there. Of course my option is to take it back to dealer, but with no CELs who knows what they are going to say.

Anyone experience this with new '08?

 

No... its not an issue.
at times it takes a crank or two to prime the pump and get the fuel flowing

I have had the same problem on my 2005 Coupe.

i recently also had it in the shop to replace the 'bad' throttle body, and it hasn't had the prob since.

 

What portion of the TB was bad? its a mechanical unit, though it is possible that a senor could be bad. the G8 is a throttle by wire unit also, NOT mechanical linkage

 

sorry, i accidently deleted your post... but I read it

I doubt it... hot rodding has little to do with the car running badly. If it was your ecu responding to a tough day, it will return to normal shortly. Could be many things, including the fuel system as I suggested. rough vibrations are directly related to the low idle so they are one in the same. I am sure once the idle raise, it was running fine/smooth again.

 

I popped the hood and let it sit for about 3 hours and went back out, drove for about 10 minutes and started it again in my drive way. The idle was back to 700 and no problems. Who knows. The dealer wont find anything anway if there's no CEL. They'll just say they can't duplicate the problem and nothing is wrong. So, I'll be waiting to see if it happens again.

 

There ya go... enjoy your ride, the new accord is nice. I love mine

 

if the problem persists...take it back to the dealer, it should still have warranty right?

Funny I had an 08 a little while ago that the customer had some "rough running" concerns. During test drive the car seemed to have a miss and when idling it vibrated like a SOB. All of this was intermittent. No CEL. Anyway turns out it had a cracked spark plug. Had under 1000 miles too.

If your car is fine now I wouldn't worry.

 

sure, or even a intermittently firing coil pack could cause a rough idle...

 

Thats weird. Never happened to me.

Thanks spoon! If it happens again, I'll be taking it back.

 

a sensor in the throttle body was bad, or so I was told. The service guy told me that with a drive by wire system, this kind of problem is A.) harder to diagnose and B.) you can't just replace the sensor

They couldn't replace the sensor by itself, so the whole unit was replaced.


Strange thing is, my TCS light was on when the throttle body went bad.

 

I dont believe you can not buy the sensor seperately...
