Hi Anker, thanks for your thoughts and I do see what you explain. Today I reconnected the ScanGauge II and managed to see a P0335 code!. Checked on the forums and found that its the Crank or camshaft position sensor. So I physically took a look at the sensor in the car and also checked the connector wire but all seem to be fine. I started the engine and since it was cold it started without any issues, waited a while for it to warm up a bit and confirmed that the engine can rev up till red, so I left the car to warm up fully and as anticipated the car started to have a rough idle and also will not rev up more than 4500 rpm. When at idle and warm, the car also stalled. So I left the car for a while with engine off and re attempted to restart, it was cranking (so no battery issues) but will not start!. Waited for a further say half an hour and tried restarting and in fact although took some cranking it did start.It was also hesitating when revving more than 4500 rpm.
So now I am more lost than before. I am assuming that if the hall effect sensor CPS is faulty or maybe defective then it should not be related to engine temperature and should be troublesome even when the engine is cold, no?
