after looking for a 95 Cab because of OBD1 I bought a 97 cab with 40k miles and now have to worry about SAI problems. would love to hear from a few of you that have not had that issue to. Maybe i can dodge that bullit for a while

none yet but under 40k on car

I firmly believe that properly operating check valve will go a long way in keeping your SAI passages clear. This check valve can be exposed to corrosive wet exhaust gases, it is steel and will corrode and eventually no longer seal. Thereby, allowing exhaust gasses to back flow through the passages and eventually clogging them.

Do preventative SAI cleaning. I bought mine with 67k miles and the PO did SAI cleaning once because CEL came on (i don't know at what mileage). It solved his issue. He said SAI cleaning doesn't always work and then shop I talked to has several methods they use to clean it.
I'm at 73k miles now with no issues (knock on wood) so far.

I also read that some managed to just reset the error code and it would stay way for a few hundred miles so you can pass emission.

without a clear service history i don't know if the check valve has been replaced. Should i do it just as a preventitive measure. by the way thanks for the response

53,000 miles, not a problem. Love this car. mark

As far as I can tell, unless you have seriously worn valve guides, the SAI port cleaning and a working valve will take care of this w/o having to resort to a top (er side) end job.

I've had two CELs on a 53K mile 1998 Cabriolet. Both were for misfires and were self clearing.

The whole, "OBDII cars are time bombs & I'll never own one" is a bit... misguided? (no pun intended).

These are all older cars now. We are simply the stewards of a historic, great looking, fun to drive car, that with any luck at all will have a following long after we no longer own them.

54K miles...15 years...no SAI light.

No light here, knock on wood. I think it is a little over hyped, but anybody who gets the $7500 bill, would quite rightfully disagree .

I agree with the above post, a functioning check valve is important. Also using a good oil with some zinc is important too for engine wear. Whatever you do DON'T start a what oil to use thread Just search for that one - trust me.

Nobody really knows 'why' some cars are more susceptible than others. Too many variables and not enough controls but I wouldn't worry about it too much. Just enjoy the car and btw, you are supposed to post pics of any new car purchase around here

A big contributor is the oil fill level - overfilling will result in stopped up air passage ways
