Just to recap for historical data:
1. Purchased the car knowing that it needed work. PO had the correct MAF housing but the incorrect aftermarket MAFS. Car had surprisingly good gas mileage and sometimes acted like it was starving for fuel. Engine would fall on its face with about 75% throttle.
2. Cobbled together a 55mm housing and MAFS from a 92 N/A bird that I had as spares. Car ran pretty good but mileage and throttle response was down. Suspect it was running rich. Key on engine off voltage about .7. Engine running idle about .9v.
3. Purchased a used correct MAFS, car would barely run. MAF voltage sat at 2.5v key on engine off.
4. Purchased another used MAF, checked key on engine off voltage at about .7. Popped it in, cleared memory, started the car and took it on a drive. Nice snappy throttle response, will watch the mileage.
Thanks very much KMT, you the man!!!!
