Car dies after I give it gas once warm
Hey guys,
Having an interesting problem here. Just did a ton of maintenance/mod installs. The car will start but once I've let it warm up, after I give it gas it will will die. AFR is fine showing around 14-15. Only code I pulled is 0037 but that's bc I installed the delicious tuning flex fuel kit. Other mods I installed are ID1050X injectors, DW300C fuel pump, new spark plugs and coil packs, delicious tuning boost controller, the verus cam plate, the aluminum intake manifold (the 2015 model is plastic) and the EVAP delete (just unplugged connector and zip ties the hoses). Already tried replacing MAP sensor (Omni 3bar) no luck. Any suggestions? New tune was uploaded as well. |

Make sure the bolts on the DI driver are tight and none are missing, it grounds through them. Curious if they rescaled for the different injectors.

Hey so the driver side fuel rail cover is removed (Non-ECU Side). Need to trim it to fit the new intake manifold. Are there any grounds on that one? The one with the ECU (Passenger side) is installed and all bolts/Connectors installed that connect to the ECU.

Assuming you're on ECUTek, do your throttle position sensor values look sane?

I'm at work rn so I'll check when I'm home, and yes ecutek. Anything else I should look for? I assume by sane you mean like 10 while not pressing the throttle. Think I remember seeing that on previous logs before this happened.

Did YOU do all of the work? If not, I'd suggest you take your car back to who did the work/tune and have them fix it. If you did the work/tune, I suggest you take it into a shop and ask them to fix it for you. sorry - no help - |

Yep probably the human factor strikes again. If you did the work go back over everything you did. What is you MAP at idle? Possible intake leak. Could be something connected wrong. Get a log to your tuner. Take a close look at your AFR if you engine is dying it can not be 14-15.

I'd double check your install, then talk with your tuner. It's almost impossible for us to point you in a direction without a log.

Back in the day, all you needed to be a "tuner" was a dwell meter, a timing light, a feeler gauge, a 9/16th inch wrench and a screwdriver - |

Hey guys,
Yep human factor stroke this time. It was a leak at the throttle body. The coupling was pretty loose. It felt tight on the clamp but it wasnt. I also retuned the car with same tune just in case there was any issues there. Car runs great now! |
