You mean all that is happening and the check engine light is off, and no
codes?

Start with getting the codes, check fuel pressure. Check all engine grounds
and the BAP.

Check timing... make sure it's advancing and steady.

I converted my old '88 PA car to MAF currently have a stock '88 VA car. '88
non-California cars didn't come with the MIL option. There's a spot on the
dash but no bulb in it. I'd doubt that when the MAF conversion was done the
OP put the bulb in to make it functional.

Yeah, there's some *serious* problems with that car. Ouch. Any mods other
than the MAF conversion?

Sounds like you are in "Limp In" mode. The CPU is inop and all the
electronic gadgets are in their default state if so. It's real easy to blow
the CPU when mess with the sensors, or try to dump the codes using the wrong
procedure. (I did this twice to myself.)

I don't think the Limp Mode was available that early. Someone correct me if
I'm wrong.

5.0bob,

I just changed over to mass air on an 88 Cougar motor that's in my son's
89 mustang. It would hardly run and wouldn't idle. Without going into
too much discussion, its major symptom was that it was running rich. (It
has no cats.) After severely beating my head against the ground and
harassing everyone in here I found that it was the injectors.
Appearantly it would run OK as a speed density but for some reason it
wouldn't or couldn't as a mass air. I changed to new injectors and now
it purrs.
