92 Stalls and immediately restarts

jrandy · #1 06-20-2010, 08:49 PM

My 92 stalls at speed, sitting still, speeding up, whenever. It dies with no warning and then immediately restarts. It will go weeks with no problem, then die 4-5 times in a day. Any help is appreciated!

I would suspect the MAF sensor.

My Claret is doing exactly the same thing. On rainy days it can stall 3 times in 10 miniutes.

I suspected the MAF. I checked for codes - none. Is there a way to check if is the MAF before I throw several hundred on a MAF?

Doubtful if its that intermittent. Given the almost 1 to 1 correlation I have seen here regarding your symptom and what it turned out to be, id try to source a used MAF from another member here. You can try cleaning it first if you want though.

I had the same issue with random stalling and immediate restarts. Was the MAF. Replaced with new Subaru part, no more stalling. Try cleaning with CRC mass airflow sensor cleaner first.

I seem to have the exact same problem. The car will be driving fine and then just stall out and I have to stop and restart it. Usually it will then drive fine. Sometimes it immedietly stalls again though and has to be restarted it.

I have removed and cleaned the MAF. I have made sure the connection to the MAF is good. I have tested the MAF with a multimeter and it seems to be getting power.

What else could this be or should I assume it is the MAF and buy a new one?

You can try opening it up and re-soldering it, the instructions are in the how to documents. It is pretty easy to do, and it completely fixed my stalling issues.

Could you point me to it. All I found there was the "How to clean the MAF"

Nevermind. It was in the cleaning document.

Had the same symptoms so I soldered mine from the DIY and works perfect. I will have to find it for you.

A further development. Now it seems to have a very erratic rpm at low speed. Like it's having a hard time idling. The idle speed also seems very slow.

I tried cleaning the ICU by spraying some maf cleaner in the tubes and that seemed like it helped for a while, but it goes back to being very rough and hesitant a bit afterward. Could a dirty or malfunctioning ICU make the car suddenly stall out of the blue?

Does this still sound like an MAF problem or something else?

httrdd · #12 03-17-2011, 05:44 PM

All the same symptoms that I had.

Yeah, I think I might try that tomorrow. I found I have a soldering iron. I just need some solder. Never done any of this before though so it might be iffy, but if its messed up whats the harm.

No worries, I never soldered anything before I did mine, but turns out it that it is one of those things that is hard to mess up too much.

Does it matter what kind of solder I get or is it all pretty much the same?
