i have a base 3.4 2005 impala. recently when accelerating (normal speed) it would almost have a few hiccups. I was told it may be the plugs and wires. my car has 65k on it and never had new plugs. so i got them changed and i was told there was a small arc on one of the old plug wires and that may have been it. Well since then (last week) it seems to accelerate fine, but every now and then when sitting still in idle, i can feel the car vibrating. wtf? my brother, who has built his own drag car, says it may just be a dirty sensor. anyone else have this kind of issue and what fixed it? thanks

Elaborate on what you mean by vibrating... do you mean misfiring?

no, i don't think its that. the car will, once every 15 times i put it in park about to shut it off, will shake, very little, but enough to where its noticeable. Then it wil be fine for a couple days, and then once, then fine for a couple days.... etc....

If it's happening at idle, check your idle air control valve. That can stick and cause vibrations at idle.

What do you mean "they won't break wil they - lol"? Ehh?

Engine or motor mounts are rubber bushings, that isolate the engine from the A-frame or cradle... A motor mount can become dislodged, deteriorate with age or time, and will need a replacement.... If there's a motor mount thats missing, you will notice it everytime you accelerate especially from a dead stop

Try cleaning the MAF sensor and TB with MAF sensor cleaner and dump some fuel injector cleaner in the gas tank. I do that every 6 months and never had any problem with any of my cars.

the MAF sensor is located off the throttle body assembly between it and the air box.

If you're just sitting and idling, and it randomly feels like its misfiring or dying for like half a second, its kind of a feature on our cars. Laughing

Mine has done that since new, and in an old thread other people said the same thing. You should be fine as long as its not doing it constantly or dying.

Due to your car's age, cleaning the MAF and running some SeaFoam through the engine and gas tank is a good idea anyway, and yes change the plug wires, 10 years is a lot of time-wear.

finally got the fuel filter off, and it poured out pitch black oil like fuel out of it.... we'll see if maybe thats why it was hesitating... only time will tell

update: still hesitates, and cleaned MAF sensor the other day.... i guess i'll have to let the awesomely expensive GM Goodwrench techs examine it for a buttload of cash. it only does it when i accelerate, it almost feels like for a second it wants to go but isn't getting everything it needs, then goes away.... who knows
