I'm throwing a code 43, fuel supply system, in my 92 lude. My car only stays on if i give it gas. It cant keep its own idle and ends up just dying out, so its obviously not getting gas. But what exactly do i need to replace to fix this problem?

 

bump

 

i was throwing a 43 on my ef hatch and i just replaced the o2 sensor and it was gone!!

 

if only it was that easy. I replaced my 02 yesterday and still suffer the same problem

 

other than the CEL and the dying idle, hows the motor doing? running good, no smoke, etc. etc. ?

 

yeah the motor is running good, just cant stay on...

 

Test fuel pressure. Check for vacuum leaks.
