Can a motor mount that looks okay really be bad? I have a bad vibration in my 96 firebird that split the engine block and I'm wondering if it could have damaged the motor mount in any way.
I have never had a car with bad motor mounts however when I used a come-along to tie the motor down on the drivers side this stopped the motor from flopping around considerably. I hate to think this vibration is trans/flywheel related but it still could be at the same time.
This vibration is bad and will shake the whole car, random missfires are seen by the ecm however I talked to a PCM programmer and he said the PCM could interpret these vibrations as random mis-fires.
Nothing else can be found wrong with the motor at all and it ran good in the firebird it came from. Could a bad input shaft/cluster gears cause this as well?
So post some of your motor mount issues that caused vibrations! The trans used to flop around but a new trans mount fixed that. I feel vibrations in the belklhousing and transmission case. This is not driveshaft related the car does it idling and clutch position does not affect it. I bought a remanufactured flywheel so that could be a culprit as well.
