Hello Kin Chan,
A mechanic used a code reader and the code P1345 shown on his reader. He told me it could be the crankshaft or the cam. So I took the liberty to change the crankshaft sensor but the light is back on after a few miles.

is it just chk engine lite came on??
how bout driveability issue?
how much u pay the mechanic for diagnostic?
did the mechanic pull the freeze frame data out??
if so what other pid datas shown?? such as rpm,3X & 18X signal???...whats the timing at?..
if ur mechanic just pull a code and didn't charge u..then he didn't do a diagnostic...and if he clear ur code out...he's gonna have to try on the same condition...induce the code back and diagnose from there?
u wanna know whats wrong???...if u mean what possibility ..that depends ..do u have any formal training of auto repair....must need professional level training on OBDII to understand whats the definition on this crank code protocol....i replaced bad wires,alternator,bad sensors,bad harmonic balancer,bad a/c location on the same code for most of the late 90's chevy truck and sub...if u want me to guess..u better get enuff equipments or parts and keep trying until 1 of it hit...theoretically if u replace enuff parts it will work..but for the late 90's chevy truck ..u must need a scanner which provide bidirectional funstion for the crank relearn on replacing distributor ..maybe crank sensor..i'm not sure till i get back to the shop tomorrow....
my advice for u if this is my car and i am in ur shoe...take it to a real mechanic and it should be fairly straight forward job.....
good luck man
