Is anyone using mass flo fi system? My system is running rich and causing a stumbling problem. Don't know if it is the computer programing or if it is a bad sensor. Need a little input.

Stuart,

I am using MasFlow with out any problems. I did have to get it tuned on a chassis dyno to get rid of the rick condition when I first got the car on the road. Call Mass Flo they should be able to give you some options...Mac

I have an older mass flow. Has your computer been chipped? Mine was not, and my fuel is not right anytime it is in open loop.

Is it a new install?

Keith Craft Plano had fits with mine until they discovered mechanic had installed distributor off timing, # 1 wire HAS to be on # 1 spot on distributor. Will run but has a Bad Stumble!

If the mass air flow sensor and the injectors are sized to match, it should run sweet after about 5 starts and 10 minutes run each time (for EEC to "learn").
Assumptions:
1. EFI Distributor wiring as per flyboy1997 mentioned.
2. Stock Ford EEC as recommended by Chris at Mass Flo.
3. Grounds all installed.
4. Initial timing w spout out at 12-14 degrees
5. O2 sensors wired correctly.
6. Fuel pressure set at 38 PSI or as recommended for your injectors.
7. IAC installed and wired right. (Idle Air Control valve)
