2003 Chevy Trailblazer. Ignition cylinder locked, no acceleration over 30 mph, battery drain, exhaust manifold leak, broken tension screw/bolt inside flange gasket
2003 if car has TBW, TAC, if the scan show sTAC failures
the PCM goes to special limphome mode. FOR THROTTLE error
s
I guess car has no tachometer? to see the transmission fails to upshift, 4 times at least. 1,2,3,4 ,RPM drops from 2 to 4.
all A/T DO THAT, ,NOT CVT . (Some CVT even have steps to make owners happy, but are useless. in fact,
only clue is screaming, well that is stuck in 1st gear and is tranny limphome( it has its very own limphome mode too)
check all fuses. and scan the OBD2 scan port, next, or go broke guessing endlessly or even putting wrong parts in to car or done wrong..
you can not fix modern cars lacking a scan tool, no way.
talking drive train or ABS. etc.
almost 20 years old and has lots of problems ignored,
which one to fix first is a hard choice that many.
