me and my friend just finsihed my 92 ls swap in my 91 dx hatch and converted to obd1 it starts up but like to idle real low and jump up at 1200 rpm and when i drive it down the road i have to keep it full-throttle for it to not bogg down and its throwin a CEL 16 , 43 i know its fuel supply though but any ideas why it could be happening

 

If you do an LS swap on a DX you are supposed to upgrade the fuel pump. I have a walbro 255. Could this possibly be part of your problem?

 

i dunno maybe i didnt think u had to change ur fuel pump ,, i never heard of anything about it , but its bogs like crazy when i drive it lol

 

bump for some help can anyone back this up that u need a new fuel pump ona dx when swappin

 

A good way to figure this out would be to purchase a B&M fuel pressure guage that plugs into your fuel filter. Compare the pressure with specs, and make sure when you rev the motor the fuel pressure increases. I don't think a walbro is necessary for a stock honda motor. But then again, I am not an expert either.
