Heavy Engine Vibrations - 10/28/2007 8:43:18 AM

Hey guys need some big help here. I have a Lancer Cedia 2001. Problem #1. Whenever the car is started and put in drive the engine makes a very high rev and aggressively "pulls" forward. Problem #2. Whenever the car is in drive but stationary (like in traffic or at stop lights) the car vibrates heavily causing a loud knocking sound around the a/c, radiator area. Its even worst when the a/c unit is turned on. Problem # 3. Whenever I have to move off from a complete stop the car vibrates and virtually stalls especially if the a/c unit is on. In order to avoid this and the loud knocking sounds and vibrating I have to use my left foot to hold the brake while I use the the right foot to gently rev the engine whenever I am slowing down or coming to a complete stop- need some mega HEEEEEELP!!!!

is it a 5 speed or auto?? if it is 5 speed you might need to adjust your clutch, it might not be letting go all the way

Would the engine mount cause all that problems?? I can understand the engine mount causing the pulling or slaming effect when the gears are changed. The car is automatic

unless we're experiencing the problem first hand theres not much we can do for you over the internet......run your car, see exactly wehere the noise is coming from....somthing is broken,there are many possibilities

So we all know that the supercharged engines need the intake bypass valve so they work in reverse. Otherwise the supercharger would just suck all the air out of the cylinder

how does it idle? if it's a real rough idle which is what it sounds like you could have a vacuum leak... along with a tranny problem... check ur transmission fluid, could be low, same thing happened to my mom's taurus
