Answer This Question
  • mindseye08 Aug 13, 2008

    we have a 2001 Monte Carlo, engine was revving high RPM's then shaking violently. Mechanic fixed in a few minutes, said it was vacuum hose. 2 days later same thing has happened. Can someone tell me where to find the vacuum hose(s) so I can reconnect myself and try to fix permanently?

IF the engine was revving high RPMS it had to be a serious vaccum leak. If the PCV came undone it would cause it rev up quite high. the shaking was from the factory set RPM limiter when not in gear (around 4,000 RPMS) the only other vaccum leak big enough would be for the brake booster. They both have a check valve but that doesn't mean much. I would start there PCV is around 5 bucks and the other is about the same. If you need pics of location I could do that also.

2002 chevy impala 3.8L V6. After replacing the spark plugs, boots, cleaning the throttle body and misc. things. COntinues to code po171.
Bank lean fault... typical from a vacuum leak or intake manifold leak. Chevy V6 has history with lower intake manifold gasket failure. Check all vacuum hoses, especially the notorious chevy vacuum accumulator line.

I need a diagram or location of the vacuum hoses on a 2007 Chevrolet Impala LT 3.5
Hears the deal Chevy really dosn't use vacuum for engine control it is more important for the AT transmission shifting .
You have main lines 1 goes to the vacuum booster control unit for the power brakes another goes to the PCV valve and depending on what you have for small lines going to vacuum reservoirs
I would look at the MAP sensor Manifold absolute pressure .
All vacuum comes off the intake manifold its the draw of air the engine needs to run .If the Map is bad you will have A LOT of of problems with how that engine runs ,It plugs in to the intake manifold 3 wire about 75 dollars maybe slightly less its a good place to start .

Changing spark plugs 2003 Impala 3.4 eng. i.e. removing and reinstalling upper intake manifold
I have a 2003 chevy Impala and it's not so difficult. Try using a small ratchet that fits in the palm of your hand, I can't remember what it is called. To install the plugs use an extension and put a couple of the card board pieces from one of the spark plug boxes in between the new spark plug and the spark plug puller socket, this will hold the new plug in place while you work with the extension. When screwing in the plug you will have to go by feel so move the extension back and forth like a light jiggle while turning to avoid cross threading the plug. After the plug is tightened attach the ratchet and slightly torque into place.
