Right well i have an 1993 type RA sti which is running poorly at low revs

I have just done an ecu cheak and come up with the following

Code 44
Code 45
Code 23
Code 24
Code 12

Any ideas the best way to fix the above codes?

I have already cleaned the boost solnoid and the MAF plus all connections i can see with brake and conection cleaner

i dont know if you know what the codes refer to but they are

44 = wastegate control solenoid valve
45 = pressure sensor / pressure exchange solenoid valve
23 = mass air flow sensor
24 = idle air control solenoid valve
12 = starter switch

when was the last time the fault codes were reset , i ask as when i had a fault with mine a while back i reset the codes and took it for a drive to see which codes came up to ensure they just werent old ones that were still stored .

i reset them yesterday after cleaning the maf and the boost contol solenoid and the car was driving fine and was pulling well. I started it this morning and its running like a bag of s*** again!

are all green MAF's the same? as im looking at buying a secound hand unit to see if i can clear the codes 44 & 45?

frodge

i believe they are but i am no expert on particular items maybe someone will confirm shortly , have you tried disconecting the maf while running to make sure it is that that is causing the issue if the car runs worse or stalls i believe i believe it shows it is working , i guess the same codes came back once you had reset them

solved replaced the maf and all is good!
