Maf/Map sensor
Can anyone tell me where the Maf or Map Sensor is on my '90 B2 2.9L V6? Or tell me if that year had one or the other of these sensors. After reading some older posts, I believe I need to find this sensor and at least clean or inspect it. A picture would be awesome! FYI...I know that there is a sensor right at the intake behind the throttle body and I am pretty sure thats the TPS.
As usual...all info is hugely appreciated!

If you are havig drivability problems you shuld start by pulling the codes, see here for a simple DIY method.. Ford Fuel Injection
MAF sensor would be a large aluminum piece in the air duct by the air filter box.. if you have one.
MAP sensor is often located on the firewall or fender and looks like this..

'90 2.9 should have a MAP. Usually, the sensor is attached to the firewall near the AC evaporator (if you have AC), has three wires, and has a vacuum hose that goes to the throttle body. Not sure there's much to clean other than making sure the vacuum hose isn't clogged.
I would agree with Conanski that the best place to start would be to pull codes.
