Dude Stylez: 05 chevy impala had 160 miles and just developed a ticking noise.. don't understand, I do all proper maintenance on it.

Gamesturbator: I have a 2004 Alero. The yellow vacuum hose you grabbed ahold was broken off (car was in poor condition when we got it) and I've had a dozen guys from autozone and mechanical forums who weren't able to tell me where the other end goes (doesn't quite look like yours in the back). This how mine looks: https://i.imgur.com/aIygLGO.jpg Someone on Scotty Kilmer's website said is a vacuum controlled shift modulator (car definitely struggles with shifting gears). REALLY need to find where the other end goes.

Ramin Taheri: This engine has been cutting out on me and stuttering at around 2k RPM especially when cruising and keeping the RPMs at a constant. I have spent a lot of time and $$ at the dealer and every time they say they've fixed it hasn't been fixed. Now, they are saying it's the catalytic converter but I am not sure I can trust them anymore. Can someone please advise? I would be very grateful for any insight.

Josh Wallace: I have a 2001 Chevy Impala 3.4. Sometimes when i am driving it. An i am accelerating quick or when i floor it to pass someone it will rev up like it's going to take off. An then all of a sudden it starts to hesitate or acts like it's getting to much gas or to much air. But as soon as i let my foot off the gas and hit it again it goes. Other times it will do the exact same thing again. I have changed the fuel filter, throttle body, air filter, plugs and wires. An it is still doing the same thing. Any suggestions???

James Dixon: the name of a lion coming off a Buick 04 with 3.4 motor coming off the water pump running to the driver side going into the firewall anybody know the name of that tube is mine is dry rotted and leaks water

Jesse James Hurtado III: I Have a 2001 Pontiac grand Am Gt 3.4l ram Air and Its at 300,000 Miles and It Runs Like its New I Really Would Love To Strip it and Race it out But No Knowledge on What To Get or Where to Go

Ganster Dae: I have a 04 imp i think it having the same issue that yours was having

Devin run it up: I have the same problem with my pcv breather ...I order new one...will I have a problem if I take off bracket that's over it ...

branden carman: Wheres the upstream o2 sensor?

smokin442200: Dude awesome video, my alero 3.4L has a weird idle mostly when its in drive at a stop light or drive through. A mechanic told me to check vacuum lines. Thanks

jennifer ellis: My son has 03 grand am (same engine) the car is turning over but won't crank. Fuel pump is ok. Thought it was crank sensor (could be) I wiggled all the wires and it cranked up. Drove today. it won't crank again. I noticed the wire (the hose on top with a curve) it's off. Like it had black tape around it and it completely came off. Could this be the problem? Your hand went over it and you said it was vacuum hoses. Not the one in front but the smaller one just above it.

Elise Kegley: I found out that the problem was the oxygen sensor , Bank 1 Sensor 2 It is a downstream sensor located after the catalytic converter.

Elise Kegley: 2004 alero, 3.4 v6 ,i have to pump the gas to start it and it will idle and quit . it also has a funny egg smell to it. i changed the plugs and it didnt help.

Radioactive Gamer: I bought a 2001 buick century with the same engine, and it has a missing manifold hose that I believe is transaxle, where would the other end of the hose have gone to if it were still there? The port is just opened up, and it causes rough idle until I place my finger over it. Can I just plug it? Or does that hose serve an important purpose?

Ediberto Leal: I beleive the 00-05 Chevy Impala base model cars have these engines. :)

gerry kline: what is the name of the line that is in front of the intake the has a fitting screwing into the top of the thernostat housing and goes to the reservoir?

Danny Ritzendollar: my car has a very bad misfire and it makes a loud hissing noise when I Rev the engine I can't find the problem and it's getting worse

mike cunningham: on the dis system u mention a vacuum does that line go to the upper intake right next to the alternator?

CAR MAC 1: dose the culd air intak freak up your car ?

nate grover: My 2004 Grand am has 231,000 on the 3400 engine , and has only needed a power steering pump (although the computer and a few other electronics were repaired becuase the car was struck by lightning after about 2 years of ownership). Does anyone else get an odd shearing sound that oscillates when cold? The sound goes away after a few minutes of running.
