Car Problems, R33 Skyline.

[alpharisc]

I have a late 1995 model skyline, with Series 2 Engine. I have a problem when it gets hot, it basically stalls when I press the accelerator quickly, then release. It also starts to run rich after it has been running for a while, I have changed the ECU, changed the AFM, changed the O2 Sensor, Spark plugs, changed the oil, oil filter, fuel filter... what is involved in keeping these cars running ?.. what decides the fuel mixture, what could be causing this problem ? does anyone know a full list of sensors, and components? if anyone has any idea, just let me know.. I am going to try a few other AFM's, and O2 sensors, to make sure there are a whole pile of faulty ones..

the afm controls the fuel mixture check you cooler piping for leaks

or if you have an aftermarket bov

there is a check you can do that checks all the sensors...i cant think of what is called(its too late) but im sure someone else here knows what it is:D

Reset the ecu

soudns liek its running way too rich and or ur afm is stuffed

i had a stuffed one, put down the pedal - revs just die

[sniffy]

now that im a little more awake, diagnostic mode was what i was thinking about...if you dont know how, do a search in the maintenence page

Swap in another R33 ECU.. you never know - it is just a computer after all and computers can go wrong.

Shane,

Still racking my brain tryning to think what it is and I still got no idea.... and for the rest of you

Swapped AFM for working one

Swapped ECU

Swapped O2 sensor

Full service

still not fixed??

It won't be cooler piping cause that would be a consistent problem, not 10 minutes after driving, not the BOV cause it would do it when it's cold too...

The problem is after 10-15 minutes of driving the car goes stupidly rich.... when cars warm up the ECU actually runs them leaner (like a choke)....

Hmmmmm..... any one got any ideas cause I'm stumped!

Doc.
