question = I recently replaced intake gaskets and all gaskets with intake (throttle body, distributor, upper and lower intake). When I started the Blazer idle was fine, I revved the engine and still seemed fine. I went for a drive and after reaching operating temperature the engine would not rev up. If you rev slowly you can rev fine, if you rev fast will not take fuel and sounds like popping through air cleaner. The check engine light came on and showed bank 1 and bank 2 O2 sensors low voltage. Got any ideas?
How to Replace Intake Manifold 3400 V6 I am replacing the 3400 V6 intake gasket and need to know the torque(ft/lbs) and torque pattern for the intake. Also, are there any tips you have to prevent coolant leaks from reoccurring on the intake
1991 chevy z71 Engine= 350 Repairs= new pick up coil,spark plugs. Question = truck cranks will not start, getting fuel and spark, set crank to 0, pulled distributor cap and button is pointing at #1,when cranking step on the gas and it pops through the TBI. Need some help, I'm thinking stretched timing chain ?
Answer: This could be a stretched timing chain, or it may have jumped a tooth. Usually if it has done that, the distributor rotor would not be pointing quite at number 1 cylinder when it should be. You could have a flat cam, or worn lifters, or both. The older trucks were known for that at times. You say you're getting fuel, but make sure you have proper fuel pressure. It should be around 10-13psi. A clogged fuel filter can cause low pressure and low volume, so check that too. Also, if you have a plugged catalytic converter, that can cause popping and backfiring since the exhaust pressure has no where to go. Could be a broken distributor, too. I'd start with the easy stuff to check first like fuel pressure, etc, and go from there
