Unstable Engine, Gear Won't Go In Park

[vineetag]

Although my 97 LS 400 (185K miles) seems to ride fine, when I try to put the car into Park, the gear locks out in Neutral. I have to turn the engine off to put it in Park.

The dealership said the Neutral Lock switch was bad and would charge $700 to replace. They also told me to push the bypass switch in the gear panel until I can get the switch replaced.

Also, my check engine light has been coming intermittently for a couple of weeks, so I took the car to another local mechanic. He told me that the engine was 'unstable', and refused to work on it. He said it could be the linkages, or the motor, or a few other jargon things I didn't follow...

Any suggestions?

thanks,

I'd swing by a local AutoZone and have them read the check engine light and post the code on here. 185k is childs play on a LS400; the mechanic probably got scared off by the mileage and the extra troubles it might entail.
