Question type: Maintenance & Repair

My 2000 blazer with 4.3 vortec has a bad hitch to it when its cold, but when the truck
warms up it runs like a top, It almost acts like its losing fire but its has great fire, I have
been told its my crank sensor any other ideas?

Can I assume you have a Check engine light on? Did you have it scanned? It can pinpoint you to the crank postion sensor.http://blazerforum.com/forum/2nd-gen-s-series-1995-2005-tech-41/2000-blazer-4-3vortecv6-rough-cold-start-then-purrs-when-warm-79256/

Suspect intake manifold gaskets.
