Ive tuned my car 2 times. And ever since the first tune, my car sometimes bogs or even stall when i BARELY tap the throttle. Its kinda like its choking. I tap the throttle, RPM barely moves, then it drops to like 400rpm or even sometimes stalls. Happens when fully warm.

So does anyone know what possible tunning errors could be which will cause this? I idle 900, car runs great. Sometimes also, when i tap the throttle normally, the RPM dips before climbing up. I think this also has something to do with it.

Overall its a very minor tunning issue, but i really need some info on how to fix it...

thanks, Armen

 

Either poor injector setup or poor tunning.

There are too many variable to make an assumption without exact map details.
Better to have the map posted.

 

i dont have datalog to post my map. I guess can take pic of my commander showing the map.

Just throw out any ideas, timing? too much fuel?

wat screen should i take a pic of?

 

my guess is it's too little fuel....
when it's cooler, the engine will bump more fuel when starting the car.. once it's warmed up... it'll be back to normal voltage and there your car might be running lack of fuel on idle....

check fuel pump, check tuning..
