STILL dooing it.
I tought i solved my problem(redone MAF connections) but after 2-3 weeks of driving it came back...
So problem is that i start the car, fine , runs perfectly. I hit the gas to rev up... ''fuel cut'' lets say at 5500, drop pedal and let idle ... rehit the gas and ''fuel cut is now at 5000. And ''fuel cut'' drop like that in linear way till it stalls. Restart and its the same thing. I say fuel cut *** i have a wideband and its max lean when cutting...
Fuel pressure is ok and never drops. Fuel filter is new. Tried flashing ecu with fresh program and resetting ecu.
The car was fine, flooring it and it was responding good!!
I'm thinking my maf is tired but i guess it would not be ok at startup and drop like that....???? And fuel pump would not keep 3 bars constant if it was the trouble i guess.
Any idea? i'll try to make a datalog but since i do not have a laptop i'll do it this weekend. But i can tell you it's the same exact problem as previous time, that was solved... i'm not really shure how....
Noticed that the tps only revieve 2.98v and ecu sends 2.98v to TPS... this is not optimal but dont think this is my problem...
ANY inputs would be very appreciated.
