Kasandra Martin: I have a hose leaking. It is on the bottom left of the top of the engine. In plain view on your video. Runs from the water pump to a steel hose it looks like. Can you tell me the name of the hose?
Eddie Greene: I have one that would crank and backfire But won't start someone told me it was a crank sensor changed it still the same what can it be
Cody Wakefield: I've got a 2003 Monte Carlo and I notice this engine likes to rev up to 3k rpm and then choke for a second then can gas up to the 4-5k rpms is there any fix to this? It's the exact same motor as what you just shown
Brian Smith: mine is starting the tapping sound some people say its the rocker arm bolt that came loose or stripped out and a few say its narm im haveing a hard time finding what it really is. a buddie of mine said it has high miles and told me to do a oil change. we will see
ClawedAssasin: anybody know why my cluster on the dash continues to every now and again just have all the needles go down to nothing and a parasitic amp draw
Eli Eli: I've got a 99 grand am gt with the 3.4, runs great drives great, but only till the battery dies, just put in new alternator and battery and still won't charge the system, and thoughts ?
George Highsmith: have a 2000 pontiac grand am gt with the same exact motor and i am having trouble finding the right heater pipe on the backside of the lower intake it is leaking bad and the pipe needs to be replaced but nobody can seem to find the right pipe i can find the straight one but the one i have has a sort of s bend in it and nobody seems to understand where it came from or can find one like it
WOLFEGANG ZOOTOWN: I hooked it up n seems its trying to work out its problem. it's been broken for some time now due to the heat. I am at 197,000 miles the heads replaced n a full tune up. still feels like it's got life in it.lol

WOLFEGANG ZOOTOWN: hey so on the manifold there a vacuum line that's by the egr. it's the hard vacuum line that's white. what does it go to or what does it do. mines not connected at the moment.
josh martinez: having the Air filter so close and direct to the Mass Air Flow doesn't throw off the Engine performance and fuel ratio??
Chris Bevins: I have a 2004 Chevrolet Impala 3.4 you have to step on the gas to get it started and it stalls when you're coming to a stop but so far I've replaced the mass airflow sensor and I'm in the middle of doing plugs and wires being that they were original and it has the car has a hundred fifty thousand miles on it old man owned it car super clean in the best color white
Chris Bevins: thats not cold air ! its short ram at best !
David James: 3400's are known for head gasket failures. You can do a combustion test on your coolant by renting the test kit from autozone. Or you can get a scope camera (Costco in 2016sells them for under $60), and look at the passenger side rear cylinder as that is where the gasket blows first. Look for a shiny clean cylinder that has been steam cleaned by coolant leaking into the cylinder and steam cleaning the piston head. Then check the other rears, then the fronts. You can stop testing when you find the first clean piston. That tells you that a HG job is needed. Do not drive it or overheat it any more. Get the heads milled, and get 16 new tty (torq to yield) head bolts. Follow the procedure exactly.
Steve Roberti: I just acquired an 03 rendezvous with this engine. It idles too high, in gear with the foot off the accelerator it will cruise at 45 to 50 mph, need to brake to slow down. At a stoplight, if I pull it into neutral, it will rev up over 3,000 rpm for a few seconds, but then settle down around 1,600 rpm. The throttle cables seems ok, there is slight slack and the throttle seems firmly closed. I couldnt hear any vacuum leak, but after watching your video I will go make a more thorough inspection. Check engine light is NOT on.
Jerry Kutche: I have a 2004 alero. This problem came on gradually. When I go to start it with my remote starter it turns over tries three times and fails.. If I get in car insert key and turn it same thing it turns over great fails to start.. If I tap on gas pedal and move it say an inch and let go the car starts like it should.
had the Throttle butterfly cleaned out today.. Was very very dirty.. Brought car home put in garage like normal 6 hours later same thing.
Sux as now we have snow headed our way.. And remote will not work.. Any suggestions.. please.. Thanks Jerry
Leroy Kniep: were is the fuel line
Al Marshall: My 3400 is pouring antifreeze behind the starter as fast as I pour it in it comes right back out any help on this
Michael Giles: I noticed that on one of the two small hoses that go from the radiator to the surge tank on the passenger side has a little small red cap with a hole in the middle and it happened to be loose so I just hand tightened it back down. not sure if this caused and ptoblems. could it have been letting air into the coolant system? I figured I would go ahead and flush the system and start with new antifreeze and bleed it and see what happens.
