Air intake leaks...
I bought my CV from a state motor pool 3 years ago and when I first got it I saw that they had recently serviced it with new oil/filter and it also had healthy trans fluid & antifreeze, a newer air filter,etc. It ran great and I've done little to it except for oil changes and a new fuel pump as I've only driven 12k miles in that time and it's been mostly highway. It now has 134k on the clock.
Today, I changed the air filter and cleaned the MAF sensor. I removed the plastic shroud that covers the manifold for access to the thermostat. I then noticed that one of the tubes that go into the rear of the intake duct was barely in there (the larger one that goes into the rear of the TB) and was loose enough to suck air. Also, I noticed the air cleaner housing was warped a little and there was a small gap that would let dirty air get past the filter (fixed that). It ran well before and got pretty good MPG but it now runs smoother...no surprise there.
Question: Since it had two places where dirty air has been getting sucked into the motor for (at least) the past 12k, is there anything recommended to help clean out the crud that may be in there?
