Especially the part about having a mass airflow sensor and NOT having MAP sensor on the same vehicle. That will be a shorter list.
Your truck has both mass and map sensors for example!
Any vehicle I have ever seen with a mass airflow sensor also had a MAP sensor! That's all I was trying to say!
THANK YOU!

Sorry, I did read what you said, but I mucked up what I meant to write in my earlier post. OP's car has MAP but no MAF. And the list of cars with MAF and no MAP will be lengthy, so I'm not going to bother.
But it looks like we both have something to learn here. I did some checking, and yes it looks like my truck does indeed have both. So, I was wrong here. I'm not sure if all newer EFI systems have both, but my truck at least does.
However, the TPI intake (from a 1988 Corvette I think) I have in my garage has MAF only, no MAP. My neighbor's fox body Mustang has a MAF sensor but no MAP (actually, it has the sensor, but they used it for checking atmospheric pressure, and didn't connect it to a vacuum line). There's two to get you started, and there's a lot more pre-OBD II cars with MAF and no MAP, which is what I am more familiar with.
Then there is the EFI I have on my '68 Chevy C10... it has neither.
