Vacuum leaks on 4kq

[Brady Moffatt]

Hmmm,

My 4kq doesn't react much at all when I remove the dipstick or the oil cap.
Nor did the one I tested yesterday.

Might there be a difference between CIS3 and CISE under those conditions?

Then again, I'm getting crappy mileage and have a small warm-up issue, and I
know nothing about the one I test drove. So maybe vacuum leaks are a
possibility!

If I try to remove the dipstick on my car, the engine runs terribly. if I
try removing the oil cap, it stalls instantly. And I do not have a turbo I5.
Sounds to me, like you may have some pretty big vacuum leaks and the PO
"tuned" it to run with the leaks...
