Jim.
How should the starter cables be connected? I'm having cold start problems,
too.
I know my temp sensor is out of order, and she seems to run way too rich.
For the moment I have a manual on/off switch and a little potentiometer8奓 ed in on the temp sensor wiring, which enables me to from the drivers
seat manually "fool" the ECU to enrich the mixture. I kind of imitate the
sensors behaviour. With the pot I can regulate the resistance and the
mixture. When she starts getting warmer I turn off the switch, ("sensor
hot") and goes to "normal mix" state.
It works, but not very well... she often get "flooded" and I get foule plugs
and lousy mileage.
I like to restore the cold-start and warm-up systems, but I am suspectible
about if everything really is connected right. PO made a engine swap, so who
knows?
I guess some day I have to tear down the whole FI and restaurate it piece by
piece...*sigh*
