I am trying to fix a misfire on my 2000 Grand Caravan 3.3L flex-fuel engine. I removed the air intake plenum to gain easier access to replace the plugs and wires.

As long as I have the plenum removed are there other items I should consider replacing at this point? The van has 185K on it, and many of the parts have not been touched since I purchased it with 70K.

Any suggestions are appreciated.

Thanks.

 

pull the injector rail and make sure you don't have a leaking injector
