What should we check??? My buddy has a 03 DS when he bought it new at the dealership the first start it fould the plugs, changed them ran fine.About 12 weeks later after seting for a while it did it again. And again Three diffrent times. Funny thing is after you change the plugs it runs like a stripped *** ape.It only does it after seting for a while.Thanks for your help....

Same problem that mine had. Dealership had a 03 with the same problem, they adusted the pilot air screw a 1/4 turn in and reccomended I do the same. Now it runs better and I havent foulded any plugs since it was new. The dealership told me that its a known prob with Bomb with either carbs not being set up correctly or the choke not coming completely off.

 

Thanks That makes sence we will try that.
