Propane question

If it keeps going into open loop that could definitely cause it to run rich...basically like having the choke on. Probably wouldn't be a bad idea to go ahead and do the 4 wire heated O2 sensor also.

Do you know what type of fuel pressure you are getting?

Kevin I would put a hotter Thermostat in it, sounds like computer thinks it's not warm enough so it's running rich.

I don't remember the numbers, but they were within Edelbrocks specs.

Edelbrock says to use a 195 stat for best performance. Maybe the multi-port is pickier than the TBI was. The TBI ran ok with the 180 in it.
