A problem I have had was with a bad o2 sensor. The actual o2 sensor inside was grounding out and blowing ecu fuses. God that took me along time to figure out.

i would consider that, only problem is the o2 sensor is brand new.

also, for ***** and giggles, Ive disabled the o2 sensor in crome to see if that would help, all it did was make partial throttle run like ***.

should i try disabling the ELD?my injector wires have never been cut, ever...and the entire engine harness is pretty new.all grounds check out fine.

i dont get how that could be, nothings been changed at all. man i really need to just get this thing up to leed and let him check it out. help tune it at the same time.

Dont you hate all the silly ---- with cars

yeah this one is very frustrating too. I have a feeling replacing the turbo isnt gonna do ---- with the ecu cel issues at all, but I guess its worth a shot since it needs to be swapped anyways.

I know the o2 sensor is new, but I'm liking this idea of it grounding out inside.

try unplugging it. yes, it will throw a code, but drive it, see if it still flickers the CEL on decel and blows the fuse.

i think you're right, i just took off my turbo and downpipe and noticed that my o2 sensor rubs on the metal part of the radiator tank, wires were pinched pretty good, that would explain the decel (motor tilts forward) issue. ---- i shoulda located those bungs better. oh well ill just put the stock o2 pre-turbo on the hf mani if i have to.

ill mess with it when I get the turbo and stuff back in the car tomorrow, I'll also have my laptop cpu tomorrow too so maybe I can get it on the wideband and see what the tps is doing as well.

i blew one once, it was a harness wire, that wore its casing off.

I used to blow some up last summer

It was my ECU plugs that weren't plugged in right

FooK

mine was the o2 sensor grounding out...did i already say that?
