If indeed it is your CPI, after you fix the CPI, change your oil ASAP ! Gas in your oil will kill the lubrication properties of your oil. Change it. Also, I've seen many posts about catalytic converters going bad after CPI problems (due to excess fuel and rich mixture ruining the catalysts). Might check your spark plugs too although extra gas may burn away quickly.
Hopefully you've found some of the great pictures on this forum about the CPI.
Good Luck!

I can't see any washing but it does smell strong of gas and looks very wet inside and very dirty.
From Reading through these posts and talking to machanics I come to realize that people that have had carbon problems with the egr, ect.. is most likely from a non repaired gas leak with cpi or nut bolt. I been told it is the most common problem with the jimmys and it is also the reason you produce soo much carbon, so I would recommend anyone with my first problem I had with the EGR carbon issues you should check your CPI unit, it may be the reason you are having carbon problems.
Can anyone post a list of all the new problems I am going to run into?? LOL Thanks for all the help. This website saves alot of money.
