Fuel pressure specs. for 1994 cav. 2.2 L

A buddy just called me, he's looking at a 94 cav 2.2 When coming off idle it runs fine at first and then misfires and acts like it's loading up with fuel. He scanned it and got a "misfire" code, but nothing specific. He's going to check fuel pressure but can't find specs anywhere to know if he's in the ballpark or not. He'd like to narrow it down a little more (he's thinking erratic fuel pressure regulator) before proceding. Any help or suggestions will be appreciated.

thanks, Joe A
