Kyle: I just replace my upper and lower intake gaskets on my 2003 Buick Century 3.1 V6. After everything was put back together, the engine will start but will not stay running unless i'm giving it gas. I can keep it running until I release the gas. The spark plug wires are in the correct order, and the wiring harness is connected correctly. No gas smell in the engine bay, fuel pump pressurizes, and all vacuum hoses are connected. Any idea would be a huge help. Thanks!
Jamie Rutherford: I have a 2000 Alero with 201,000 and I don't have piston slap. Only thing I've done engine wise besides oil change is I had to put a water pump on it when I got it. It had 192,000 when I got it. Otherwise I love it. Car still runs like a champ. I do have one slight issue that's weird. in the summer the car runs a proper temp but in the winter time the temp gauge won't even make the first line after cold unless you're setting idle. Even then once you get moving again it drops right back to that temp. So the heat ain't as hot as it should be.
Usucceed: 2003 Olds Alero 3.4L This summer after sitting for about two weeks my car would not start, it would crank but not start. I put new plugs in and bought starting fluid and it would only start with a few shots of ether. I replaced fuel filter, fuel pump and pressure regulator during the course of the next couple months and still the only way to get the car to start after sitting overnight is to use starter fluid!!! What the heck is next?
Bailey Steinmann: My car died on me a few times. it died yesterday and woulnt start. i got it towed and did the fuel filter, no change. it cranks strong but just wont start.
Nick Smith: i have a 2001 olds alero so i had a blown intake manifold gasket i changed it cleaned alot of the crap that collects on the inside of the engine. anyways i started it up and it runs good once it heats up to operating temperature. it starts to lope i guesse would be the term for it. any ideas?

Mike Hardman: trying to get the oil pan off mine, all the bolts are out, hammered on it w/ rubber mallet, no budge,. no explanation anywhere .. can't even find a diagram of the damn thing,.. when i search the only things come up are top side photos, or 2.2's .. i need info on the 3400.. you got anything? and no, it's not leaking from the wires like the frigging goofs at autozone tried telling me, i need to replace the oil pan gasket,
Amanda Brooks: my car was slightly over heating so I changed my thermostat.. Found a freeze plug lodged in the thermostat.. Now it's really over heating and leaking fluid.. wasn't doing that before.. How do I fix it. 2000 Chevy impala..
zack mack: what is a vacuum line can it cause your car to shut off
Linnex Miles: First and foremost I wish to give a shout out to author and participants of this board. A dedicated GM 3.4L Engine Discussion board is pretty awesome!!!
I have a 2003 Chevy Impala. The only difference between my engine and the author's is that there are motor mounts at the front of the engine. I need to change the back spark plugs. I am rather large in stature (6'2'', 275lbs), so feeling around the back to access them like some of you shorter and skinnier guys do is not an option for me.
According to what I researched thus far, GM states that it is best practice to rotate the engine. While there are videos out there that shows you how to do this, but the challenge is finding the resource for specifically for the application for the 2000-2005 chevy Impalas.
My question specifically where do you strap the engine to perform the this procedure? I want to do it the right way. Thanks!!!!
Hale Cooley: lose the airfilter put the factory one back on you're just sucking hot air from the engine bay with that open airfilter
galaxybeing1: I own two Aleros. One is '99 with 221,000+ miles , 2nd is '04 with 88,000+ miles. Piston slap you explained exists in the '99 but not the '04. How many minutes do you say heating up the engine at first start up? Good vids, btw. Thanks.
tyler wagner: think I may have a vacuum leak but not quite sure. just think I have a performance issue. and it could be from that. do you reccommed I just go ahead and replace the entire pcv hose?
tyler wagner: can the loose vacuum hoses cause performance issues as well?
Mike Toucheck: I saw a lot of comments nohow to change the back plugs on a 3.4 litre motor in my Chevy venture..after a lot of cussing I found the only easy way is to remove the coil pack bracket..I did take off both motor mounts and pull the motor forward but that is the easiest way..12me nuts on back of bracket 10me on front!!!!
Mike Toucheck: I cannot see where the household. that connects to the air intake hoagies.. it is on top about 2 inches from the clamp to the throttle body.. I'm wearing my glasses but I still can't see where it goes..thanks for all the tips though..
BiopsyHeaven: You meantioned some noise it tends to make during a cold start. I have a slight knocking that happens upon ignition. It always happens first thing, but runs flawlessly after warming up.
