I'm posting this for a friend who just bought a used '89 TBird 3.8
engine, 60K miles about 2 months ago, ran great until today. Now it's
starting to hesitate while driving. Seemed to do it so far just
driving on 35 mph roads after engine was off a couple of hours. Seems
OK on freeway after warmed up, but stopping at the end of the offramp,
it stalled. Idling in the driveway it stalled, but started again. Fuel
pump? The weather here has been in the teens last few days, but
symtoms just started today. He just had an Bosch O2 sensor replaced 2
days ago, what's the possibility of that gone bad or installed wrong?
We were thinking fuel line freeze up, but it was colder last week
with no problems (Cleveland, Ohio). Any advice, thanks much.
