Just installed LCE big bore throttle body and full LCE exhaust system(no cat). Now I’m running pretty rich, I can smell fuel on start up after being warm and it’s not normal like it bogs but starts on demand. Any ideas? I’ve ohmed out TPS when I installed throttle body

 

Could the Cold Start Injector be providing fuel when it shouldn't?

It could be leaking, or the Start Injector Timer or ECT sensor is/are bad, or not connected? Might be telling the ECU to run the CSI when it shouldn't?

Could your regular injectors be leaking, making there be extra fuel in the intake manifold before it should be there?

I'm just throwing ideas out. I'm sure one (or more) of our experts will give you the answer instantly, but those are the best I can come up with...

I’ll look in to CSI. I just adjusted MAF by 4 teeth according to LCE power package install. So I’ll run it and see how it does thanks
