1994 LS 400 problems -missing sputtering
First I apologize if this has been addressed previously or in another forum. I bought this 1994 Lexus LS 400 over a year ago and I love it or at least I did until about a month ago. About a month ago I started encountering problems with the car's operation. It began missing and sputtering and acting as though I had purchased some bad fuel and that still could be the problem, but I am starting to have my doubts. I live over 2 hours away from the nearest Lexus dealership so taking it into the dealership to check codes or diagnostics isn't a likely option. I have begun exploring the possibility of purchasing a diagnostic code scanner to check and see if it may be a sensor going bad. So far I have changed air and fuel filters, plugs, and changed brands of gasoline plus added a can of sea-foam fuel cleaner. It has stopped stalling however now it will take spells of running well then running like crap. When it runs well, it is the car I fell in love with, when it craps out, it won't even pull itself up a hill without manually shifting to low1. So I have a couple of questions for Lexus owners or DIY'ers out there.
1. Have you encountered similar problems and if so, what solutions did you find?
2. What diagnostic computers have you had experience with? or used? I have been looking at the Innova 3120 code scanner. Has anyone here used one and is it a simple tool or complicated to use or is it even useful? I am considering buying a scanner to fix the car cause I still love the car, but I can't just start replacing things or else I will simply send it on down the road to a new owner which I really don't want to do.
Please help if you can and I want you to know it's appreciated.
