TPS? MAP? MAF?
Can somebody post a pic or try to explain to me where all these sensors are on my 305 TBI V8 Camaro? Please. I have no clue. And in the air cleaner I see a little plastic thing sticking up with 2 wires connected to in underneath the base of the air cleaner housing. My idle sometimes surges a 100 RPM or so when In park. I need help. Maybe the sensors need cleaning. Please help

TPS is on the throttle body, MAP is on the firewall, MAF is on a TPI car.

Where on the firewal is the map? Doesn't it run to the engine to get the manifold air pressure. and what is the little plasic cone thing that is sticking up from the air cleaner housing?

Inside the air cleaner is the IAT (Idle Air Temp) sensor.
If you mark a spot 1/2 way between the distributor and the heater box, attached to the lip of the cowl, there is a square flat black gadget - that's the MAP - it has a vacuum line to it and a connector.
