Yes.

LADIES AND GENTLEMEN I WOULD LIKE TO THANK WILLWREN FOR ALL HIS HELP HE HAS GIVEN ME

Bozo. You're the one who found your broken mount and balljoint. Not me.

Ken, while you're in there, I strongly suggest you check or just replace the stabilizer bar endlinks. They're on the shelf at Autozone, Energy Suspension in the yellow pack, with the red bushings. There'* a thread here in 92-99 on the subject. Your car is old enough, they have to be shot.

Part numbers, prices, and detailed pics with instructions. Your Haynes manual will do the rest.

This is the post I was referring to.

I have exactly the same 2 error codes on my '92 SSE supercharged, and these codes have appeared sporadically ever since I bought it in 1999. I've never noticed any driveability issues because of these codes, and I'm absolutely certain that I've never tried to start the car while in gear. In regards to the passkey fuel enable circuit error code #58, I used to get the error when the switch contacts were still wired in the steering column, but years ago I disabled that wiring and added a resistor so the key doesn't need a resistor pellet anymore, and the error code still occurs sometimes. And yes, I've cleared the codes regularly since then.
It seems that nothing needs to be done to fix the cause of these 2 codes.

On a side note, I've never seen either of these codes stored in my '93 SSEi.
