1JZ-GE Auto Help

[JavidZee]

Hi there guys Eid Mubarak,
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o:p></o:p>
I'm having a problem with my 1JZ- GE Auto
<o:p></o:p>
It’s like averaging 1km per liter; I have serviced the Throttle body, injectors and intake manifold but the issue in not resolved at all. Also the plugs are soaked with Fuel when I open them !!!<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
Also the fuel pump is off a Mustang I don’t know could it be an issue with that….<o:p></o:p>
<o:p></o:p>
Need help urgently experts ???

any other symptoms, check light, misfire etc?

I would go about checking the injector resistances first - and do a fuel pressure test too, if the FPR is blocked you may see insanely high fuel pressure. - I would bet you have a big error code too, such rich mixtures would coat the 02 sensor real bad and it'll throw a check light.

Nope I dont think the check light and all are wired up but I wanna do so, have not checked any error codes yet.

I'm getting worried now, actually I took the car to a local guy he said he serviced and fixed it but later in the day i found out nothing at all was fixed

[akifjanjua]

bro carefully check ALL vacumm hoses.. there are a number of vacumm hoses around the throttle body.. ur engine may b idling high as a sign of vacumm leak

[Xulfiqar]

are you good with electrical wiring? - and how many wiring plugs does your ECU have and whats the toyota part number printed on it. Once we get to that point we can locate a check light

btw does your engine have the diagnosis connector?

[SER_GTR]

I Am Damn Sure CEL Is Not Hooked Up.....!!
where are you located in karachi....!!?? i might can help you...!!

[SER_GTR]

@xulfiqar.....he might have that diagnosis box maybe..maybe not but who knows its wired or not....!!
The CEL should be wired very 1st.....!! who Knows many of sensors are still left blanked and un-wired....!!

[Xulfiqar]

^^ you are right too, Ive seen soooo many swaps done like that its just a sorry state.

btw what happened to the original rotary? - why did you not just get it rebuilt.
