1993 Lexus ES300 Q&A
1993 Lexus ES300 Question: Do you think I need a tune=up?
If you have not had a major tune up with wires, plugs fuel filter and air filter performed in 30,000 miles then it's over due. This would be a good place to start, also have your throttle body cleaned of any carbon deposits and have a fuel system cleaning to clean any varnish off of your injectors, or you can use a bottle of Techron and just put it in a full tank of gas, use the brand name of Techron, the other generic fuel system cleaners don't do nearly as good of a job. - dandd
