Lexus RX300 engine starts but stalls unless accelerator is pressed, possible need for belt and water pump replacement at 185000 miles on Lexus RX300

Some Lexus RX300 owners report experiencing engine stalling issues when starting, which may indicate problems with the timing belt and water pump, especially around 185,000 miles. These owners note that the timing belt should be replaced every 60,000 miles to avoid costly repairs, as a broken timing belt can lead to expenses ranging from $3,000 to $5,000. Additionally, many owners recommend replacing the water pump simultaneously with the timing belt to save on labor costs and ensure both components are covered by warranty. Neglecting these replacements can lead to further complications and additional expenses, making it crucial for owners to have both the timing belt and water pump inspected and replaced as needed to maintain the engine's performance.
