93 lt1 camero z28 starts and idles ok soon as i step on the fuel pedal it completely falls on its face dies. Does not matter what way shape or form you push it it dies! Any ideas

 

Welcome to CamaroZ28.com ! ! !

Is the SES light on? If so, have you scanned it for codes? Is the engine stock or modified? Sounds like it's getting air, but not getting the fuel to go with it.

”New Member Introduction” isn’t the best place for “tech” questions. I'll move your post to “LT1 Based Engine Tech” where you are more likely to get help.

PS: “camero”…….???

I wonder if its getting to much fuel and not enough air. Extremely dirty or clogged air filter possibly.

 

93 is speed-density. A plugged air filter would increase vacuum, lowering MAP, and lowering air density. That reduces the ECM's calculation of mass air flow, and should cause the injector pulse widths to be reduced. My thought is that there may be a problem with the MAP sensor. Big mass of air gets pulled in, manifold absolute pressure increases, but the MAP sensor doesn’t respond, too little fuel. Alternatively, the throttle position sensor may not be indicating the sudden opening, delaying the ECM's response to the increased air flow, and delaying increased fuel flow..

Alternatively, ECM may be seeing the opening throttle, increasing fuel flow, but as noted in post #3, there is no significant inlet air flow. In that case the increase for TPS volts may be offset by the reduced air density, resulting from a dirty air filter, and still throw off the fuel enough to cause a stall.

Doing a real time scan or data log of the ECM would be needed to evaluate that theory. Or direct measurement of MAP voltage and/or TPS voltage while the throttle is opened.

But for now we just need answers to the questions asked in post #2.
