so i'm looking for the oxygen sensor and mat sensor, and i've looked in the haynes booklet, and that's no help. and it's really cold outside, so i don't want to dily daly around looking for these sensors. so do any of you guys know where these sensors are? by the way this car is an 1986 z28 with a 350.

 

A 350 in an 86? (O2 Sensor) If it uses GM exhaust manifolds its on the Drivers side above the y-pipe connection. As for the MAT sensor it depends on what injection sysetm your using TPI or TBI?
