The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX.

1991 Toyota Previa Problems
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.
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
It is important to regularly check the valve clearance as the exhaust valves may become too tight. This will lead to valve failures, which are expensive to repair.
If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.

1991 Toyota Previa Reviews
I bought my Toyota Previa new in 1990... a 1991 model. Since then, my children and I have put 489,000 miles on it. Today I learned that I may need a differencial. Other than that it's an amazing vehicle and I intend to replace the differencial...but I need to locate a used one somewhere. This will be the first major repair to my awesome vehicle. I love driving it just like I did when I drove it off the lot! If anyone knows of place to get an inexpensive differencial for it, please advise. Thanks.
