I have a 2003 Lexus GS430 - 2 years ago, I got a complete tune up. Recently my car has been hesitating terribly at idle, and during initial take off. I've taken it to Autozone to have the diagnostics run on it, and based on the misfire results have had all coil packs, spark plugs and fuel injectors replaced.

It has actually gotten worse. My husband does all of the work, and mentioned that I may have gotten some "bad" gas. That gas has since been emptied and I used a fuel injector cleaner, filled up the tank and the same still exists.

The check engine light, and both the VCS lights appear on the dash.

Any other suggestions???

I purchased a new GS350 F-Sport last year and feeling like my older baby is a little jealous because it never gave me any problems!!!! But believe me, I love my 2003!!!!

Check for vacuum leaks on the engine. Thats a common cause of a poor idle on the V8s as they have a lot of vacuum lines around the engine
