Hi there I'm new here, but I have a problem with my 1995 t-bird and could really use some help.

1995 t-bird 4.6 w/ 56,000 miles.
was running a little weird. when pulling out into traffic, or hard accelleration, even in park, full throttle, the engine would rev up to 2700rpm, then stay there and go no higher untill i let off the throttle a bit. normal driving is ok, but full throttle was terrible. I replaced the Throttle Pos. sensor, with no change. then i changed the Mass air sensor, and the car wont run at all. But, and heres the kicker, when I unplug the MAS the car runs GREAT!! like it was new, and very fast. everything would be fine like this, but i was wondering why it works this way, and how can i get it running like it should be with all the equipment properly connected. oh, btw just for kicks, after i installed the new MAS i disconnected the battery, so the computer would reset its operating peramaters and function fine with the new sensor, but that didn't work either. help!!!

Well that is quite a dillema. I was looking at this PDF file, http://www.autoshop101.com/forms/h34.pdf , and it states that a car can run poorly or stall if the plugs are blocked on the MAF or from what I think it could be a bad sensor they installed. If it runs great without it then that is good for now but the MAF is a important sensor, at least to me. So maybe read this PDF file and se what people say.
