Hello, I'm in desperate need of assistance here!!! The check engine, TSC, trac off & brake lights are remaining on...(brake light goes off sometimes). My car all of the sudden started running really rough, almost like it needed a tune up. I took it to Advance & had codes read & every cylinder was misfiring; it actually read 30 codes. Took it to Auto Zone & the only code was for spark plugs. At this time, I did know that I needed new brake pads & had needed them for some time. Then I decided to take my car to Aamco to have it checked. After keeping it for 4 days, they called me & told me that I needed a new timing belt & water pump (amongst other things) that totaled up to over $2000. I had a trustworthy man look at it & he told me to change plugs & wires as well as coil pack to see if it ran better. When the plugs were pulled out, they were drenched in oil, obviously causing car to misfire. Changed plugs, wires, gasket (which was leaking). Not to mention, I paid to have brakes done as well. Complete tune up has been done & it ran great for an hour after that. Now, the car runs fine while its not warmed up. It runs great while in motion most of the time but when I stop, the brakes are almost gone & the car runs so rough, that it sometimes even cuts off on his own. I've literally changed the gas gap, changed some motion sensor, plugs, wires, coil packs, gasket, new brakes & tried to reset the computer by leaving battery unplugged for 20 minutes to reset it. None of these things have solved my issue. Is it possible that Aamco was correct & that I should put new timing belt & water pump on it to make it run like new again?! I'm taking shots in the dark here & started with the easy fixes in hopes that it'd save me $, but at this point, I've paid 3 guys to fix my car & the issue still exists. I'm now over the $2000 that I would've originally spent on a timing belt at Aamco, so I now know that when owning a Lexus, you can't do anything cheap, but I need to know....is the timing belt the issue here cuz it seems like if the timing were off, it'd skip & run rough at all times when drunk. Please help someone!!!!!
