Hi,
I have a 1994 ford escort 1.9 lx wagon. recently, the check engine
light has been coming, but it doesnt stay on. if i accelerate, then the
light comes on, but if i break and come to a stop, the light goes out.
i thought that maybe the transmission fluid might need changing, so i
took it for a flush and refill, but that didnt fix it, so i got the
error codes read. it is an obd1 error code readout and the codes were
181 and 186. does anyone know what these mean and what would need to be
fixed??

thank
