Brought my car in for service when I noticed the VSC and VSC OFF Warning Lights on, after my car had been displaying noticeable vibration when idling. My usual mechanic hooked my car up to the machine, and told me that I had a misfire in Cyllinder#6. I asked him why my Check Engine Light did not go on, and after some investigating, he told me that someone had pulled that bulb out (I bought this car with 36K miles on it from Lexus of Norwood in MA as a Pre Owned Certified). After doing some fishing around, they told me that the Valve covers were leaking, and oil condensation had gotten on my ignition wires and onto one of my sparkplugs, so they would need to replace the sparkplug, wires, and valve covers. After spending almost $400 (ended up replacing all six plugs), this did not do the trick. They then tried a fuel injector cleaner, which was to no avail, and now the car ran worse and vibrated when accelerating and idling.
I brought the car back the next day, and after further investigation, they told me that I had RUST in my gas tank which had contaminated the fuel line, rail, filter, and the injectors, especially Number 6. So..... after spending another $1900 to get the tank replaced, the line replaced, a new rail fabricated, and the injectors reconditioned, as well as getting a different (used) fuel pump, I got my car back.
While the car is running fine, my car now has issues starting when it sits for over two hours. My car will wind, and either start after extended winding on the first try, or I will have to try a second time in order to start. If I then start the car again in less than an hour, it has no problems starting. They tried re-installing my old fuel pump which they had cleaned, thinking the used one that they had installed was no good. Again, to no avail.
Does anyone have any suggestions??? This car has 126K miles on it, but I have always taken great care of this car and I always keep it in immaculate condition. I'm also wondering after spending almost $2700 (includes rental), should I just say "Goodbye" to my beloved Lexus? Any help would be greatly appreciated.
