EFI questions

[Jeromy Gibson]

Ok I finally got my truck out and drove it for more than 10 mins after my TBI swap. Two problems came up, its running very rich. Does anyone have pic showing the proper port for the MAP sensor on a stock 91 intake. Can someone explain the proper way to hook up a 91 3 wire altenator. there was no wiring for the alt. on the harness I bought and I don't know if you can just jump it like the old ones. Thanks for any help. Jeromy

As I recall the map plugs into a port on the back center of the throttle body. Mine was doing the same thing at one point and it turned out the EGR was opening at the wrong
time. If I get a chance I'll try and check and get a picture for ya.

i looked at mine last night and it is plugged into the port in the front, could this be the cause of it running rich?
