I tried searching for this as I seem to recall it not being uncommon, but I can find nothing. The cars a 1992 SC400. Any help is appreciated, or if you know of a thread thats covered it, thats nice too.

Also, it will fire for a second on rare occasions and die instantly. It still seems to be connected somehow to sitting for a while. The ECU crossed my mind....have you seen this before or guessing? Do you know of a way to check it?

Well, I got a new used air meter and got no change. Car still turns over but won't even fire. The car has spark. Fuel pump is a possibility I suppose, but the plugs seem wet. I suppose a compression check is in order.

Did you check the Fuel Filter..? No, nor did I check to see if the CD player is skipping. :P

I could use a bit of help. My 92 SC400 will not run and I have a strong feeling that it is the MAS...however, it's not for sure. The maf is a very expensive part to buy and have not solce the issue, so I am looking for anyone willing to help me by letting me plug their MAS into my car. Its just one plug and 2 worm gear clamps and would only take a few moments. You would be doing me a HUGE favor that I really need. If there's any of you willing to de me this favor I would greatly appreciate it. I will provide some gas money or lunch or whatever as well.

I scanned it. it has the following errors codes: 24. Intake Air Temperature Sensor signal 31. Air Flow Meter signal (Vacuum Sensor signal) Any Ideas?

I have a 1992 SC400 that I bought about 5 days ago. The alt died after 4 days and I swapped in a new one myself. The car ran fine and I think this is unrelated to the issue at hand. Last night on my way home I floored the car and it began to buck. The engine would rev up to a few k then bog down. The car made it to my driveway about 1/2 mile away but was very unhappy. This morning I went out to drive my car and it started normally, back out of the driveway normally and then when I put it in drive, bogged really bad and died. I started it, it made it to the end of the street barely...revving sluggishly and wanting to die while I had my foot all the way in it. At the end of the street it died permanently. If I crank it it sometimes starts for a split second, gets to idle rpm and slowly falls down running lumpy as hell. Holds at 250 rpm for a sec then dies. Other times it won't start at all. There is a CEL. How can I check this? Is the car obd1 or 2? I assume 1... It has consistent spark, at leats on the driver side bank. The plugs are fuel soaked but that could be the effect of what ever is keeping it from running, not the cause. Timing belt looks normal and fully tensioned. The problem appears to be less severe after sitting for several hours? Not sure about that but I think so. What should happen if you unplug the air meter and start the car? Will they idle?
