[Peugeot-L] RE:1991 405 S will not stay running ... the plot thickens

Ok, so I pulled the codes today. Had 5 or six codes. So I cleared them and attempted to drive it. Got a block away and the light came on. Pulled a code - 52 - try another ECU. I had an ECU for an 89, and although I know I should not have done this, I pluged it in and the car ran fine. (I unpluged the idle control device.) So I drove it around for a while, maybe 40 miles or so. Check Engine light came on, checked the codes, 52 - try another ECU. Kept driving it to see what would happen, because it was running fine. The car stalled, would not restart, changed back the 91 ECU and it started right up! Drove around for a while, maybe another 40 miles, Light came on again, code 52 - try another ECU and 33 - Air flow meter. I cleared the codes, and it was fine the rest of the night. Any ideas?? Also, am I damaging anything by running the wrong ECU in the car? Another list member offered me a used one for a reasonable price, but A) I am not sure that is really the problem and B) if it is, I would really like to wait a few weeks, as I am still recovering for Christmas bills. Any thoughts or ideas?? Thanks,

John
