on the transmission tailshaft housing
It's located just before the oil filter.
The 91 has the 4.6L engine and has a MAF sensor located just after the air filter box so it has no MAP sensor.
Any size SBC engine will fit and is compatible with a 91 Firebird. A 350 engine is the most common that is used for installing in a 91 Firebird.
On a Prelude 91 Si, you can find the MAP sensor by looking at the black box which is mounted on the passenger side firewall. You should see vacuum lines that run to it.
Hey, I got a 91' firebird 305 tbi that had the same exact problem...it's your speed sensor or O2 sensor....(or both)
Cam sensor not used on '91 Tempo. Only introduced in '92 model year.
The intake rear...next to Alternator...This is what I have found out.
in the ecu
There is no such thing!!
The 1991 Geo speed sensor is located on the side of the transmission. The speed sensor will be on the left-hand side of the transmission.
On the intake manifold.
