Just saw this. Sounds like:
CPS iffy but not sure if they go bad intermittently.
Fuel pump.
MAF

MAF appears to be working; when I disconnect the connector, the engine bogs down. The only other change I made recently is changing out the fuel filter since I thought that might be part of the problem. PO did not take care of the car.
In your other post you mentioned to check the fuel rail pressure. Will look that up to see how its done. What should the pressure be? Will low pressure indicate failing fuel pump?
Thanks

Yep. I don't recall pressure but if it ain't there with key turned over it's a bad FP. Mine had zero pressure. Fuel rail port is same as AC ports.

Did you install the fuel filter the right way round?

YES! The hard start issue has been going on for several weeks. Ignored this problem until intermittent stalling at idle started. The stalling happened only on one drive. Another hidden gremlin. The hard start issue is hit and miss. Some days I can go out and it will fire right up, other days, it takes a few try's. On those days, it idles rough for a few moments, sounds/feels like it going to die until I apply the gas, then it settles out.

Sounds like a fuel pump issue to me.
