I need to know where the maf is located on a 305 tbi. Any input would be appreciated.

No MAF. The MAP, follow the vaccum hose on the rear of TB (F port) it goes to the MAP, on top of the firewall.

Yep.
Your MAP Sensor like said, should be on the firewall on the passenger side of the car.
If I remeber correctly the plug has 3 wires, may be 4 but pretty sure it's 3 wires.
And a single vac line.

I'll check it out. I replaced the o2 sensor yesterday, and what a pain in the a**.. I got to it from under the car. I am still getting a check engine light. The guy who sold the RS to me gave me an o2 sensor, and said it needed to be replaced, so I replace it. Seems to run good though.

have you pulled the codes yet to find out what problem the light is saying you have? Throwing parts at a vehicle drains the wallet reallllly quick.

As stated pull codes and check for disconnected vac lines or defective vac lines(split)
