RE: [T3] 68 Fastback FI (?) Issues - Diagnostic Help Requested


I recommend not going to work. Just drive around with your son.

Hi Jim -

I just completed a diagnostic run with fuel pressure gauge and voltmeter
from voltage regulator.

I had my son in the right seat and watching the gauges - we took two loops
of a 7-mile route - half surface streets, half highway.

Throughout, the fuel pressure held steady at 28 psi and the voltage went
from about 14.5V at idle up to about 16-17V at speed.

There were a few times I felt the car bog a bit - most noticable from a dead
stop during acceleration to street speed (~40mph).

For reasons that may be due to the Heisenberg Uncertainty Principle - the
car actually "felt" better than it had in awhile... the next true test would
be to take it on the trip to work (24 miles one-way - mostly highway).

Any thoughts at this point?

Thanks,

MJS
