Code 34 MAP
87 350 TPI, stock. I get error code 34, which is Manifold Air Pressure sensor signal out of range. They didn't use a MAP until I believe 1990. I have just a MAF sensor. My engine light is always on and car runs perfectly.
Why am I getting this code?

Re: Code 34 MAP
I believe Code 34 = MAF for 87-89.
