hey ive got a ae92 1992 model with the supercharged 4age...lately the eng light has come on and it just wont rev/drive properly..ive had mechanics look at it and they can't find codes but one today said it feels like its in limp mode? if anyone has come across this before let me know...or what can i look at myself? i was told the sensor inside the air box had been permanently disconnected? is that bad?

i think club4ag has a code list on their website for almost every 4age.

where you located mate,

have snap on and or access to a toyota scan tool

4AGE/4AGZE's have a built in diagnostic system, which should be able to point you in the right direction of the problem :yes:

Yeah, admittedly it's basic/crude in comparison to modern-day systems (i.e some BMW's have deleted the engine oil dipstick & rely on the computer to tell you when it's at the correct level :blinks: I thought telling you when it needs a service & what it needs doing was nuts) but it has saved me a few headaches & lots of running around with a muiltimeter :y:
