Over the time the exhaust gas recirculation (EGR) system may become plugged with debris, the oxygen sensor may also be getting slow or 'lazy' around this time. When servicing or cleaning the EGR system, it is a good idea to replace the oxygen sensor because it works in tandem with the EGR system.

1991 Toyota MR2 Reviews
Have owned my 1991 Toyota MR2 Turbo now for about 2 years. Purchased the car with about 122,000 miles on it. I don't street race or anything like that, but I do drive it hard. I make sure my oil is changed about 200-250 miles before schedule always using Mobile1 20w50. I have had no major problems. The factory turbocharger still boosts very strong. I am at about 144,000 miles now and the clutch is beginning to slip. Also I have had to replace the water temperature sender for the gauge. Nothing major...especially for a turbocharged car that is 20 years old. It is a very stiff ride with limited interior space. This isn't a complaint of course...it is a mid-engine sports car. This car provides the most enjoyment I have ever had in a daily driven car.
