sounds like a definate fuel delivery issue...
i would not go for tearing into the motor....
the i-5's are pretty much bulletproof... i would try a compression test
before diagnosing a
crankshaft?!! or even checking it.. also a timing light might be able to
help you chek that all of your marks line up.. there is one makr on the
front crank pulley, a notch and a line on the
cover of the front, and a spot in the rear, through the bellhousing, a spot
on the camshaft,
and the distibutor has a dash on it.. in which it lines up at TDC.
i would take off all vacuum hoses, check them thoroughly, maybe try to find
a fuel distributor and check that as well.... are you having a bad misfire
this would indicate a possible bad injector as well...
if it is a new engine i would not think crank unless you have a bad knock..
only ever heard of 2 i-5's ever losing a crank.. i have worn plenty of the
engines out but
never EVER worn out the crank.
there is a notch on the harmonic balancer but this would throw off
so if your timing is ok.. your mechanic is wrong...
if you think a good mechanic is expensive.. wait until you try a bad one
