I have a 2004 accord ex l i belive i have all features for this year including leather seats dual climate control etc except i dont have navigation. Its a 2 door coupe 3L V6 6 speed manual. I had a viper alarm keyless in. So this is what happened. Sat i had a viper remote start installed no problems sunday i changed my oil and changed to fully syntheic 5w 20 mobil1 with mobil1filter i also got regular gas at this getty i have never been to before. Monday tuesday no problems Wednesday morning i remote start my car and when i get in i see the engine light went on. I read the codes with my scanner 14codes 7 codes twice pending and not for each one. Misfire cylinder 1-6 and random/multiple misfire. Now ud figure the car would be sputting and everything from misfire i really dont notice a difference shes still runs good and starts right up. I called auto image in brick nj where i had the remote start put in and told them and they said its not what they did. So any ideas? Thanks for the help. Also if it matters when it started yesterday with the codes i was at half a tank. Also i tried erasing the codes and the light didnt even flicker off and all codes stayed. O and i have 112k miles

 

your timing is off. Sounds like the remote starter some how was able to jump your timing belt one tooth. I'd be very very careful driving it as you wouldnt want to slap a valve or 8.

Have you used the remote starter anymore? Ever had your timing belt changed?

 

I bought the car about a month ago i have a receipt from the guy with the timing belt done a few thousand miles ago. How would it jump a tooth? And i have been using the remote start everyday since i got it. How do i check to see if it jumped?

 

Post the trouble codes. It may have nothing to do with the timing jumping.

 

P0300 p0301 p0302 p0303 p0304 p0305 p0306 .

 

So, other than the codes, you don't actually notice any misfire when the car is on; correct?

If so, it may be the ECM/PCM misinterpreting sensor inputs. Although the codes you listed is not identical to the sequence of misfire codes listed in this Honda technical service bulletin (tsb), it may be something similarly happening with your ECM/PCM.

Normally as described in the TSB, you may see P302 and P306 together, or P301 and P305, and P300 may also be set. The fix in the TSB was a software update.

However, in your case, it may have to do with the aftermarket (Viper) remote start.

Ahh I missed the "runs fine" part, I rescind my timing comment

 

Here's a thread with a guy with a similar problem after having a remote start installed.

p0300 through p0306 cel code came on last night...now what!? - V6 Performance.net Forums

 

So how would i fix it? I dont want to remove the system i was also thinking maybe check the grounds to the computer. What do you think

 

I see that thread only difference is that my codes wont erase does that mean something else? I figured it be electrical. I dont really know what to look for but im going to look around to see if any wires looke badly connected from the remote start
