Actin weird?

RE: Actin weird?
It is possible...since the computer uses the information from the MAP sensor to determine the amount of air flowing into the intake. It uses the vacuum created in the intake to calculate what the fuel ratio should be...

Carberators used to be much easier to work than this fuel injected crapolla but I still like it.
I have decided that todays autos get better gas mileage but are more difficult to work on.
The old school stuff is easier to work on but costs more at the pumps more frequently.
In another 10 years wer'e all going to be road warrioring for gas because everything is going to be
hydrogen or electric.
What the heck am I supposed to do with my porsche and my supra, our blazer and our benz.
I want to buy the old lady a new titan but dang.

Have your Cat converter checked also..If u have 1

Yeah, the MAP sensor is used in conjunction with the TPS (throttle position sensor) and the O2 sensor to determine the proper IPW (injector pulse width). It is quite possible that the MAP sensor is causing the whole problem.

Could the distributor itself be bad?[&:]

Check the injector spray, if its like a fine mist shower on both injectors (if its duel) then that is fine. If you see droplets like rain then you have a dirty injector. If its lacking spray then you might have faulty wires to the injector. (the older TB's are known for dead wires).
Now with a RICH GAS code for exhaust, that would lean me towards a *Fuel Pressure Regulator* or the TPSgoing out. With the newer side mount air cleaners like on the 3.1, 3.3, 3.8, 4.3, 5.7's it was easy to find out if that was it due to there would be gas all the way out to the filter.
Sad part is that the MAP sensor could had just been a bad vacuum line. Usually these last a lot longer then most think on the older stuff. This would also explane excessive fuel use, due to when the vacuum line is bad, the computer will dump extra fuel in the motor. Like going from 24 mpg down to 11 mpg.

yea there is a vaccum line that comes from the MAP sensor that i have no idea where it goes to
