91 PA won't run

[dasbrow]

My 91 PA will not stay running, I've changed plug wires, IAC, cleaned all contacts on the Ignition module, checked fuel pressure. It will start but not stay running it has a very bad idle . I pop off the MAF and put it back on and the car ranning fine . I left to go to the wreckers to pick up another one but they didn't have any for my car, I didn't have time to go to the others to as they where all closed, the person driving me showed up to late at my house.

Even when I got the car running I could pull the MAF plug off and the car would run fine. But now the car does not run, starts and stalls.

Any help?

Thanks.
