Guys, Ive read about 50 pages of stalling problems on this Forum and ive found no help at all.
My cars running very rough and idles like a drag car. When foot is down, car powers fine, doesnt lose any power drives normally. Car is a Series II R33.
I have, changed fuel filter, spark plugs, checked coils, cleaned out Air flow meter/plug but still it does this.
This happend out of the blue, my fuel tank was on empty at the time. I have a brand new Walbro fuel pump. I have a Remapped ECU.
The funny thing is, after I did this, for a while the car Idled fine, especially after I gave it a booting. Then out of the blue it would idle bad. Boot it again, and same story. Today while driving it, it was constantly idling bad. Like a drag car. Its not the same noise when a cylinder has dropped, but just like a lumpy cam and at times like rotational idle.
Im really stressed out over this. Does anyone have any suggestions. Could anyone possibly give me a hand?
Could the AFM or Crank angle sensor be the culprits? What about O2 sensor, how can I get this checked.
Regards
Kim
