94 Stalling, Bucking, Poor Fuel Economy

[jaimysessanna]

Hello everyone!

I still have a 94 LeSabre with a lot of miles. For months the car has been running like garbage, and I'm finally determined to find the solution to my problem. The car will run rough, stall when you come to a stop, and the mileage is somewhere in the high teens.

I replaced the intake manifold gasket, as well as the fuel pump, and fuel filter. I have proper fuel pressure at prime and idle as well as the recommended range when the fuel pressure regulator is unhooked. Recently my father purchased the Actron scanner that will scan the very specific OBD 1.5 computer that this LeSabre has. We scanned it and it kept calling the MAP sensor.

I have looked and looked and researched and I have come up with the conclusion that the L27 didn't have a MAP sensor, the only ones that did were the Series 1 & 2 L67 and well as the L36.

I'm going to re-scan again to see if I missed anything. In the meantime however, does anyone have any ideas as to what could be happening?

Thanks!

The code? can also refer to the maf, more likely. Disconnect it and see what happens.
