sbolasingh Posted November 23, 2009 Share Posted November 23, 2009 I have an 1995 Lexus LS400 and it seem to run somewhat sluggish. It doesn't seem to have the power that a LS should have. I've changed everything that I thought would hold it back such as the timing belt waterpump, fuel filter, catalyic converters, plugs wires etc and still the same problem. Any suggestions Quote Link to comment Share on other sites More sharing options...

What are you basing your conclusion on? Any objective/scientific evidence or comparisons? Performance differs among the LS series. The 1990-1992 LS400 performs similar but some are slower or faster depending on how they are optioned due to varying weight. The 1993-1994 LS400 gained 100 pounds and performance is generally a little lower than the 90-92. The 1995-1997 LS400 lost 200 pounds on average, gained 10 horsepower and is a little faster than the earlier ones. The 1998-2000 LS400 gained 240 pounds over the 95-97 but also gained 30 horsepower and VVTi which let the engine scream and improved acceleration. So, my question is .... how much power do you think your LS should have? Quote Link to comment Share on other sites More sharing options...
