Absent knowing, having a LONG service history with the non-marque shop involved, I would NEVER take a modern high technology vehicle to a third party shop. In short, you've just been screwed. Now take it to Bellevue Lexus and get screwed yet again. But at least you'll get the car fixed properly. Well, it is unsettling to find out that I have been screwed. These guys did come across as honest. You might be right and I might have no choice but to take it to the dealer. Unless someone can suggest something different?

Yes, they did replace the timing belt. Thanks.

Hi, I am new to this forum. lately I have had a sudden problem with my 1999 RX300 with 86,000 miles and am not sure what to do next. Just last week, I had more than $3,500 worth of work on on this vehicle. This included replacing ignition coils 1 and 2 (as I was told that there was misfiring and these 2 were dead), water pump, timing belt tensioner, thermostat, exhaust manifold and gasket. I also had the 90,000 mile service done, which included EFI/Carbon Clean service, oil change, air filter, spark plugs, etc. Immediately after the above repairs and service, as I drove out, I got the Check Engine sign again. I took it back to the shop. At that time the error code was P0125 (Insufficient Coolant Temperature For Closed Loop Fuel Control ). He reset it and we went for a test drive. within 5 miles we got the engine check light again. This time the error code P1155 (Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) ). He estimated another $500 worth of repairs. My questions: 1. Would all the initial repairs cause these new problems? Like replacing the exhaust manifold, or anything else? 2. How much should I spend to fix the codes P1155 and P0125? 3. Can these 2 codes have an easier fix (like cleaning, etc) rather than replacing them? 4. The repairs were done at a shop that claims speciality in SUVs. Should I take it to the dealer? At this point, the Check Engine light stays on. Thanks in advance for your comments and suggestions.
