I need to know what to buy to try to solve my problem..
another quick question... when I replace either the MAP or the MAF do I have to pick one up for a caprice 350 with TBI since I replaced the 305 with a caprice 350??

 

our cars have a MAP sensor. it hangs on the firewall on that little spot that sticks out. they don't really go bad unless you smash it, just make sure the vacuum line leadign to it is good and sealed well at both ends. a vacuum leak will cause it to read all screwy.
also, all of the gm cars taht used a MAP used the same one. so 305 or 350 does not make a difference.(that includes my '84 cav)

so map sensors are hard to make go bad? I wonder what could be causing my problems then...
