Check out the 89-95 truck section and search there, a few people have asked the same question 🙂. Welcome to TN!

I've not been able to find the the 89-95 truck section, please be so kind as to send me a link.
I am wondering now if our '91 has a non-91 engine in it.
Do the 1991 2.4 engines have just one O2 sensor, or a second one in the exhaust manifold?
Ours has two but no obvious place to connect the upstream exh manifod sensor.
Thank you!
