Code 25 92 SC400 Auto
I have a SC400 and I just did the paper clip code checker. The first time I did it I came up with a 13 and a 25. I incidently ran some sea foam thru the unit I now only get the 25 code. What is code 25, what parts do I need to replace? Also my air bag light is on. I just recently replaced the seat belts. My check engine light and battery light has been on since I had the car (3 months). I have replaced the power steering line, battery and alternator. There is no indication of leaking power steering fluid anymore. The battery reads 13 volts. Help

If you looked it up online code 25 is for a Air/Fuel ratio lean malfunction. 13 is RPM Signal Circuit 2 but seeing as it's gone now it probably is just a loose connector. for code 25 it could be a number of things such as 02 sensor, fuel delivery or ignition problem. First thing i would start looking for is a small vacuum leak. Spray some WD40 on the engine and see if the RPM jumps a bit. If you don't like getting Oil all over your engine some water and a spray bottle will cause RPMs to drop. Either way it indicates a vacuum leak somewhere.

I did both 1 and 3
To seafoam your car:
1) use 66% on gas tank with 12 to 15 gallons of fuel. Cleans fuel injectors, fuel lines, removes moisture from fuel lines. Put it in gas tank at the gas station, then fill it with 9 gallons of fuel, so it can mix well. Just read the bottle for the normal mix ratio.
2) another 33% goes to your crankcase. so open your oil cap and pour it in. *WARNING: It thins out your oil. DRIVE FOR ABOUT 10 MILES, THEN CHANGE YOUR OIL. KABISH??
3) Rest 33% goes to the intake manifold. It cleans intake valves, cylinder, top of the piston, exhaust valves, etc. To do this, you have to use any vacuum line that goes to the intake manifold. In s13, brake booster line is perfect.

Did you reset the computer after you gave the car seafoam? This helps in removing the check engine light temporarily, but by resetting the ECU it can help the car run a little better. It won't hurt the car, just dissconect the neg. battery cable for 30 mins, reconnect and start the car. It might run a little rough at first but after about 5-10 mins. The idle will kick up and should run a little better. See if the check engine light comes back on after some driving.
