Problem with my 1998 Chevy Blazer
4.3 V6
Repair work done prior = replaced intake gaskets
tip/donation yes
GM tech = JK
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?
May have gotten some debre on the sensors while doing the work.
Plug wires not in the correct firing order.
Vacuum leak.
May have left something unplugged or
blew a fuse.
Low fuel pressure would also cause this.
Possible timing chain jumped time, or distributor not in exact same location as
previous.
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

My 98 Pontiac Grand Am has no heat. The gauge on the dash works.
The engine gets hot, and the car has not over heated. Is my problem the
thermostat or the heater core or intake gaskets ?

Question = truck cranks will not start, getting fuel and spark, set crank to 0, pulled dist
ributor 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: 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
