Replaced two Fuel Ratio Sensors. Old ones were broken, which caused misfires in Cylinders 1, 3 and 5. This mimicked significant transmission problems, dropped fuel efficiency, burned fuel in the exhaust pipes and put fuel in the oil.
Engine light was on and car could not pass state emissions test. Replaced catalytic converter with non-Toyota parts.
Stuck PCV Valve and wear fouled the spark plugs, wiring, fuel filter, fuel injectors, which created misfires and sludge build up in throttle body and intake manifold. Replaced plugs, wires, PCV valve, filter, coils boots, grommets & gaskets
The emission system vapor canister needed to be changed.
The seam weld that held the muffler to the catalytic converter broke clean. Had to re-weld. 2 ignition coils died.

Head gasket leaking oil.
Replaced Air Fuel Sensor. Fuel system and throttle body cleaning.
Oil leak under timing cover: $300-$500. Not putting more money into the vehicle. Planning to trade in car. Timing belt needs replacing: $322 estimate. Not putting more money into the vehicle. Planning to trade in car.
Waterpump, cam seals, and crank seals were leaking. Replaced parts as part of timing belt service.
Both intake and exhaust valves on cylinder #6 were out of tolerance causing a click that was getting louder. Dealer pulled valve cover and adjusted valves only on that cylinder, others were fine.
Rear engine mount failed quite a while ago but noise and vibration got worse over time and became almost unbearable.
It was replaced and vehicle felt like brand new!
Vehicle temp would start to rise when idling or moving slow. Thermostat was not working properly. Dealer couldn't find the problem at first, but on the second day was duplicated and fixed.
