Fiat woes

[Daniel Grambihler]

Chief:

You might try checking your crank sensor (I'm assuming you have one). I've
seen this type of problem on other FI systems that came down to a faulty
crank sensor (started stumbling above a certain RPM - cutting out like the
ignition was dying).

good luck - Daniel
