1993 Toyota Previa Problems
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. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.
The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.
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's been sitting in same spot for about 2 weeks, makes a weird sound when i start it, white smoke coming from muffler, had a hard time starting it at first, now start right away, its kinda cold, sometimes it get super cold a night(weather)
I've had this Previa for nearly 3 years. Two months after purchase I had a burnt valve replaced by my south Seattle mechanic. It cost me almost $2000. Two plus years later and I am in the same spot. 4th cylinder reads about 50 psi, while the rest of them read between 110-120 psi.

I have two of these, my son has one. Best car on the road!!
I have a 1993 Previa with 190,000 miles and still going strong. One of the last rear wheel drive minivans on the road. Very durable and outlast its contemporaries on the road. My two boys grew up with it and they are now driving it too. Great car!
