My engine had to come out anyway, so I redid the CIS sytem over the winter.

After dropping the engine, I reomoved the entire CIS. It allowed me to replace some of the potential leakers on the engine.

It turned out my airbox was blown-up as well. I used some marine epoxy to put it back together and installed a pop-off valve. Then, since I'm there, I replaced all of the rubber bits, vacuum hose, fuel lines, intake manifold boots, etc. I even took the opportunity to send out the injectors for a good clean/check. It isn't hard with everything out, I don't know but I think it would be tough with the engine in the car. Kinda depends on how long you are willing to have the car off the road.

As I mentioned, my box was broken and I didn't know it. I drove it for a few months that way. Never had a back-fire so I think it was broken when I bought it. It ran great but my fuel mileage sucked. Like 15 mpg. I think the PO just had it running really rich to make up for the unmetered air.

Welcome to the board by the way. I see you are fairly new. Do we have pics of your car yet? What year/model are we talking about?
