today i found out that my mass air flow sensor needs to be changed. but the prices for these dam things are high as hell. i wondering can i use any year model sc400 or ls400 sensor just to get it on the road again. or if any one is selling one. i have a 95 sc400

 

have you tried to just leave it unplugged? thats what i did.....

 

i just bought a new one and its still doing the same so im going to reset the computer by pulling the efi then letting it sit over night but i am going to also clean it.

 

Be careful how you clean it, I used CRC MAF cleaner and it killed mine.Guess it was a newbie mistake, just use compressed air and a dry q-tip and you should be fine, not sure if it will fix the problem though, hope this helps. GL

 

come to find out i checked the air filter which was nasty dirty so i replaced that and also cleaned the intake box. then i bought a new thermostat my old one was slammed shut. so it rides better now

 

Glad to hear you all good now..

 

Not sure that I have the correct forum. Sorry if so.

I removed the MAF from my 94 SC400 to clean it since the car won't idle at all when coming to a stop sign or red light. Starts right up though. The dealer says the code 31 indicates an intermittant signal.

When I cleaned the MAF on my old Ford, I could clearly see the wires in the MAG. But the MAF on the SC400 has a longer tube inside and I can't see what to clean. Can't see any wire.

Would appreciate your telling me the how and where to clean.

Thanks

 

your car can run without the maf plugged in..... that is the check i did when my car was throwing codes. its actually "faster" too... but only because the a/f is richened

 

i fixed that maf problem but the car still has jerking to it when i full throttle the car it jerks but not bad so im thinkn its fuel related so im goin to put my volt meter on the fuel pump to test that first to see if its the pump or im goin to replace the fuel filter and then run a fic on it

 

12volt mod?
