Low fuel pressure, bad IAC valve, vacuum leak, bad injector(s). You also need to check the EGR valve.
I would like to know if my 2002 chevy blazer with a stock 4.3 vortec pull 2000 lbs ?
A bad fuel injector poppet could cause that.
That would be the 5.7L / 350 Vortec.
Vortec 4.3 should be 200 hp, however, it didn't come out until '94. Standard 4.3 is 160 hp.
A spun--Bad rod bearing. NO OIL PRESSURE.
A bad fuel injector poppet, a bad spark plug, a bad spark plug wire, a bad distributor cap and rotor.
No it will not. The 96 vortec has a crankshaft sensor and alot of other sensors on the engine that is required so the transmission will work that will not interchange with the 92 engine. Even the fuel pump would have to be changed. You must put a VORTEC engine back in the 96 so everything will work correctly.
I would be suprised if you have adjustable valves.
Most likely it has a 4L60E
What would cause the engine not to restart when hot Chevy Trailblazer 2007?
maybe the clutch
That would be the 4L60E transmission. The 4L80E was used in the 3/4 tons
