Check the air inlet boot going from the air filter to the intake for rips or holes. If rips exist, this would allow air to bypass the filter and mass air flow sensor and will lead to a check engine light appearing. The code would read "too lean, bank 1." If this problem is allowed to continue for long periods of time, the EGR ports will have to be cleaned out and maybe even the intake.

Don't waste your time.
Have the intake manifold gaskets (upper and lower) replaced.
Check all vacuum lines for leaks.
Clamp all vacuum hose connections.
Do NOT replace any sensors unless the computer codes indicate.
THIS WILL FIX YOUR PROBLEM!

Replace the gaskets on the intake manifold. My tribute was doing the same thing. Replace all spark plugs at the same time since the manifold is already off. They found small amounts of oil in my first 2 valves and plugs, but other 4 were dry. My car idles great and runs great now and it was a cold morning today!!! Also go ahead and replace the idle control valve if you like. I had to replace this first in the car with idle problems. Charge for replacing gaskets and plugs and cleaning it up in the cylinders.... $250.00 and it was well worth it! I have a side mechanic and do not go to dealers or other shops in town.
