Time for new timing belt, water pump, tensioner, pulleys, gaskets, seals — get the Timing Belt Kit — the whole kit varies with each dealership.

Recommended every 90k miles / 9-10 years, so you’re overdue.

I understand owners have gone to 200k miles without replacing timing belt, but why take a chance.

Does it smoke when you start it up? Have you replaced the ASIC vacuum switching valve? I would bet there is something wrong with the intake, either the system that varies the running length is malfunctioning or you power steering vacuum solenoid is leaking and your getting power steering fluid sucked into the intake and it struggles to run while sucking heavy lubricant into the cylinders
