All,
I have a 2004 Venture with 86K. I got into it yesterday to go to the store and it started fine when I went to leave it was hard to start and would not idle. At that point I noticed a smelly exhaust and the smell of gas. After I got it to start I took it for a quick run down the street It performed fine under hard throttle however when I got back in the driveway It started sputtering again and eventually died. I did a diagnostic test and came up with P0300.
I am not sure where to start with this code. I looked at the plugs and they were black and measured .060 (irid.. plugs). So now I am thinking perhaps the cat is now clogged up or the EGR or the fuel reg or the coil pack etc....
I really don't know where to start. All feedback is appreciated.
thx.
