It's your CV joints. I had the same problem
has the same problem with a 92 Pontiac bonniville with the 3800 ended up being the cam position sensorI justot work.
possibly on of the belt pulleys or a vaccum leak
are you sure it is valve chatter,Thought i had same problem but it was the rotor on the distributer hitting on the cap due to a bad top bushing in the distributer.
yes,if the inner vacuum bladder is cracked it could cause a vacuum leak,this could cause a problem at idle also.
cause u feel cold what do u think
Yes, an internal force can cause acceleration in a body.
sounds like a motor mount is broken or a transmition mount. have those checked.
Might just need a front end alignment or maybe balance and rotate your tires.
We have one that does that. The mechanic told us it was 2 bad motor mounts, but I haven't fixed them yet (so cannot verify the diagnosis)
Just the opposite. It will cause the acceleration to drop by 50%.
Overload can cause contact chatter. Once the contact closes, the voltage in the circuit collapses and that causes the relay to drop out. At this pint the relay energizes, since the voltage is back. This cycle will continue on.
stop baggin on the car stock parts wont take it for very long the chatter problem seek a mechanic
