CEL Code 23
I'm wondering what the most logical problem would be if im getting a 23 code. Ive got a 91 3.1.
Im assuming it is most likely the MAP sensor but im not positive.
Also the engine tends to lope after it reaches regular temperature. It hasn't done it recently but now if it hits 5000 rpm the engine loses all power and drops back to about 1000 then rides like normal again. I just purchased this car last week, trying to learn a thing or two about fixing it. Any help would be great, thanks in advance.
