Here's the best way I know to fix this problem (as you said:) without paying. Make friends with someone who works at a professional garage. Get them to scan the computer and gather the codes. Or you could marry into the family of someone that works in the industry. You need to see which code was saved in the computer ( and there are MANY possibilities) before you can have any idea what to do next. Try to look for a coupon in the mailers that come to your home or in the local papers. Many shops will offer a special price for scanning your car's PCM (comp.) so they can get you in the door and make you a customer. You should be able to get this done for 40 to 60 bucks depending on where you live. It takes a few minutes, but some shops charge a full Labor Hour for the service. It's a Lexus, not a VW Beetle, so the price of ownership includes maintenance, you dig?

I am likely purchasing a 1992 Lexus LS400 with 196,000 miles from the original owner later today - what should I be concerned with during my inspection? The owner states he did a timing belt service in May...

Check for rust and check the pressure in the engine - if when you remove the oil fill cap the gases are bursting out then the engine is worn out. Check the transmission's oil  and ask him if the filter has been changed - without that the life of the gearbox has been reduced.
