Check engine light flickering

Postby skuzzy » Sat Apr 30, 2011 10:44 pm

Anyone ever have this problum before

If im driving the car in the low revs and try put the foot down to speed up without down shifting it chuggs for for a second and the check engine light flickers for a second or two and then takes off.

If ya keep it in the high revs its grand.

There is an apex power fc ecu in it so i dont no if the codes can be read from it.

In my own head i think it could a dirty sensor or else the mapping for the fuel is still at 99 ron

No smoke at all

Cleaned the maf sensor today. It was filthy and it seems to be ok now but will keep an eye on it for a few days

low rpm high load check light flicker is normally knock.

If you have the hand controller put it on to peak mode in the monitoring section with knock sensor as one of the variables and see what it peaks at.

If you can run higher octane fuel try this and see if it stops/is harder to do.
