Just have a question and was wondering if anyone else is having this issue. My 92LS has this affliction that I can't seem to figure out. When I start the car from a cold start (car sitting more than 4+ hours), I have a CEL which pops up on the dash. This light will stay on for approx 5 minutes and then turn itself off. The only time this light comes on like this is if the car is sitting for more than 4 hours, every other time, starts right up,,no lights nothing!!! I have reset the ecu in the car, b/c when I am on the road I unhook my battery and the car is normally sitting at least a week. My guess would be that I may need new O2 sensors, but not sure. What are you guy's thoughts?

***Second annoyance!! Still have the stock radio, saving to replace it for something a lil better. Anyway, once I start the car the radio will not come on/power up for 15 minutes or better (after 2+ hours of sitting), but it does still work once it does decide to grace me with it's presence. My thought is it is on it's way out, and since it is the original I can't be mad at it. Also my CD changer does not work anymore. Will eject the cd cartridge, but displays nothing but an ERR message when trying to get it to play. I planned on replacing it anyway soon, just wanted to get as much use out of it as I can. Opinions welcomed

Not sure about your CEL, but yes, it sounds like your radio is going out. I do not have the problem (yet) on my 91' LS400, but my old 90' LS400 was fine until one winter. When the interior of the car dropped below 40°, it would take a few minutes for it to come on.... then it got to where the car had to be warmer and warmer on the inside before the radio would work - then it got to where it would not come on at all. Obviously a common problem on these. As mentioned - not a problem on my current LS - YET.

The radio problem probably a connection. there are a group of wires that conect the main housing of the stereo to the face plate. they are connected by a "ribbon" (it is a flat peice of plasticwith wies running through it) over time from temprature exposure the "ribbon" peels back when it is cold and lays flat when it is warm (cold it disconnects warm ir connects) at least that what it was on my car. If you have the knack you can fix it wth a piece of scootch tape if your willing to take it apart.

Radio,,, not really gona worry about it too much. Replacing soon and I am not in my car too much for the delay to bother me. was just wondering.
Did that,, did not show any codes at all; even when the light was on. Gonna try a few more times to see if it will trip something; maybe I am not doing something right. O2 sensors are my guess too. Don't know when they were changed last, and it probably is about time to do so. Couldn't hurt any.
