NO OVER HEAT LIGHT, NO ACCELERATING...NOTHING LIKE THAT IT IS SUCH A SHAME. I AM UP BEAT AND WAS JUST LOOKING FOR PROBABLY SOMETHING SIMPLE LIKE A TPS OR FUSE... BUT HAS BEEN SAID BY LEXUS THAT THEY DON'T KNOW WHAT'S WRONG. I WAS SHOCKED THOUGH BECAUSE LEXUS DOES KNOW IT WILL BE 14 THOUSAND DOLLARS THOUGH TO REPAIR. (A NEW ENGINE) I HAVE PLEADED WITH THE CORPORATE OFFICE AND THEY SAID THAT SINCE THE CAR HAS 130.000 MILES IT IS NOT THEIR RESP. TO HELP ME WITH A SOLUTION.
