hey car came off the road not long after i posted last.
problem was not the cas.
its still doin it now and gettin worse. ive replaced my 02 sensor with a brand new one. and another known workin one.
after talkin to a few old school mechanics and a few tuners ive been told that it could be the knock sensors.. they are likely working fine but somethin is confusing them. could be outside noise, could be bad wiring. reason they say its the knock sensors is because obviously a knock bein sensed will cause the ecu to go into r and r mode. also knock sensors only measure between 1500-3500 rpm. any higher or lower in the rev range theres a substantial amount of radiant noise which can confuse a knock sensor.
when i get around to it. (hopefully in the next week) ill be by passing the knock sensors all together via a 460k ohm resistor soldered inline with the knock sensors.
basically that will tell the ecu that there is no knock ever so if it does fix it then, ill replace the wiring and the knock sensors (seperately so that i can pinpoint which was the issue incase it happens again)
