Car starts fine...but dosent run

Sorry no experience on the vehicle, but the symptom you describe seems like the engine is strangled - maybe a blocked CAT or crushed pipe.

If there is nothing obvious you need to go back to basics starting with the valve timing, fuel pressures and so forth. If it has fly by wire throttle, ensure the butterfly is responding and the air metering unit is good.

Is this a drive by wire model? Id so there is a second throttle position sensor on the accelerator pedal also.

If you hold the pedal to the floor it puts the fuel system into Clear Flood Mode. This prevents the injectors from firing and lets the already present fuel burn out. Now if this has to be done on every short trip you probably have a leaking injector.

Does the vehicle seem to crank slowly or stop and then crank when this happens?

I'm not to sure on this one but i had a very similar problem with one of my cars it turned out to the the throttle position sensor had gone bad. In my case though everything was fine till the car heated up. Then I never know what was going to happen. Most the time at lights my care would just stall when i hit the gas. I though it was a vacuum hose issue but there was no leek. If the throttle position sensor is not working or is not working like it should then the engine will not respond to the gas pedal being hit. Or will rev real high when not being hit. I hope this helps you and solves you issue!

A variance of 20 PSI indicates a problem.

Hi!

Sounds to me like the engine in fact is getting gas when idleing, but not getting enough air. Therefore my 2 cents are on you IACV (Idle Air Controller Valve). It's a small steel cylinder suspended in a rubber piece on the front of your throttle body, and its job is to supply the engine with air when idleing. This is a necessity since the throttle body valve is closed when the gas pedal isn't pressed. Take out the IACV and clean it thoroughly, also make sure that the air going from it is not hindered by any gunk or deposits on its way to the intake manifold.
(You could have someone hold their hand on the IACV when you take your foot of the gas pedal. If nothing happens it's probably dead or stuck. If something does happen there is still a chance that the air is hindered somewhere).

Good luck, let us know if this didn't help!

unplug your mass airflow sensor and see if it will run more consistently is wont run great, but better if there is a problem with it, it is located in line of the air intake coming off the air box, if that helps look inside the air box for a rats nest plugging the air meter please rate -jeff
