No MAF and NO SES? WTF...
Just noticed it.
Unplugged the MAF and started the car and no SES light, checked my scanner reading and it said 8 gr/s used to be like 13 g/s I touched the gas and it increased the MAF flow??
How can the ECM get gr/s without MAF signal and why does it increase when I touch the gas? and the biggest question is why NO SES??
I tested My stock APYU with changed inj.const and then the SES light came on?
Have I changed something I shouldnt in the bin? probably but what?
