2002 Dodge Caravan

I never had any problem. But tune ups were not a big part of my business. They have a service manual here on this site.
If you can't locate maybe they did away with the 3.3 crankcase ventilation, necessary to meter the positive pressure in the upper combustion cover area, back into the intake area. That was very important, so I don't think they did, that hose going to the intake gets full manifold vacuum, a hole in it means terrible driveability. If I see a 2002 3.3L tomorrow I will look. OK glenn hay.
No problem. The manual this site offers is so important for any mechanic or do it yourselfer. Who isn't these days? If I did not have to do this stuff, I still would. I love circuits anyway. Check back later or tomorrow.
