The fuel pressure regulator is located under the upper intake manifold on the passenger side of the poppet bank. If the regulator is leaking raw fuel the fuel will run down into the passenger side cylinders. So if the black plugs are on the passenger side that could be the problem.
I would like to know if my 2002 chevy blazer with a stock 4.3 vortec pull 2000 lbs ?
Bad coil or coil pack.
Do a compression test to determine if you have a valve problem or not and be sure the firing order is correct and don't forget to replace the rotor.
It would not be a bolt in and go swap. They have entirely different fuel injection systems.
you would need to change the cylinder heads also.See link below
Well, wearing black shoes with a navy blazer would do no harm, but my favorite combination would be, beige shoes or red ones, with the same navy blazer.
Most likely it has a 4L60E
to replace the intake gasket would be about 4 hours labor. parts would run about $50
That would be the 4L60E transmission.
The Vortec Engines with the Spyder, or octopus type fuel injectors had issues with the clip on the fuel injector harness breaking. thus, causing it to come loose which would cause random misfires. also causes could be low compression, bad plugs and wires, dirty injectors, cattilytic converters.
Bad coil, Bad damaged or unplugged crank/cam position sensor, bad rotor, distributer cap, faulty distributer, plugs wires
I would say that black pants would match.
