hi i have a 1989 toyota corolla le with the 4-AF motor and i was wondering if i have o2 sensors or and exhaust sensor because i got some gauges for it and was wondering wat i can do with them or if i have to get rid of them your help will be appreciated

If you are fuel injected - you have O2 sensors. That particular generation of Corolla were available with and without fuel injection (didn't become standard across the model line until 1990 - for US bound cars).

Why did you get gauges for something you were not sure if you had or not??
