I picked up a 91 SC automatic a few weeks ago. It did not run and sat all winter. I had it towed home from a gas station and got it running the same afternoon.
It seems the crank bolt broke and the balancer/pulley slid away from the sensor.
I had to drill out a broken crank bolt and put in another. Thats it. Now it runs but badly. I pulled the balancer, it was not broken. So I put it back on until later.
I know the balancer is an issue but I feel it should still run better than it does.
The car stalls alot when in gear, knocks under load and is powerless. The engine also rumbles/vibrates when driven and stumbles badly above 2000 rpm.
The up arrow does not come on while cranking. But it does come on when the key is in the on position just before cranking begins.
Any thoughts on cause for bad running appreciated. I was thinking cam sensor. Thanks
