It sounds like your plug wires are grounded to the engine block. IE.... melted somehwere along the exhaust route and grounded, noticeable when you put it in gear......
I don't think so, i have a 1993 cavalier 2.2L auto, which does the same thing, i put new plug wires on it about a month ago, and it still has the same vibration.
I would check your motor mounts. I had a 90 Sunbird and now have a 91 Cavalier, both of which had this problem. When you pull up to a stop light the whole car vibrates rather aggressively, but is calmed when the car is put into park or neutral. In both cars the motor mounts were bad causing the motor to jostle inside the engine compartment, but when you are actually driving the engine is torqued against the mounts and ceases to rattle. On the 2.2 there are 4 mounts, Right Front (by the engine coolant overflow tank), Right Rear (right above the trans axle), Left Front (looks like a dog bone on the bottom by the radiator) and the transmission mount (on top on the left by the wheel well).
Last night I replaced the right front and right rear and this solved my problem.
All automatic cars have one. A 97 is probably on the transmission where the linkage connects.
It is located on top of the transmission where the shift cable attaches to the transmission.
it is under the dash at the top of the clutch pedalIn an automatic it is attached by bolts on top of the transmission under the hood
Could be as simple as being in need of a tune up.
yes, the shift linkage has a switch to only allow the car to start in either park, or neutral. All automatic transmissions have a neutral safety switch. It is misadjusted or defective.
Begin by removing the wiring from the 2002 Chevy Cavalier neutral safety switch. Remove the neutral safety switch retaining screws. Reverse the process to install your new neutral safety switch.
The neutral safety switch, on your 1993 Chevy Cavalier, is located beneath the shifting column. The switch can be accessed by removing the shifting boot.
my automatic transmission is stuck in neutral. how do you get it into gear
put it on neutral
An automatic car should be left in park and not neutral when left beside the road.
If it is an automatic it will not have a clutch safety switch it will have a neutral safety switch
