Hi guys
I seem to have a problem with my rb20det
When i first turn the car on, it starts ok, but then the revs are around 0-200rpm and then I tap the throttle and it the revs go up nicely to around 900-1000rpm for warming up.
I take it for a drive, come back, or whilst driving I am stopped and the revs are about 0-200 to 500 and I have to tap it for it not to stall, like when Im stopped the battery light, hicas light etc turn on cause the car is about to stall so I keep the revs up... then when I've taken it for a drive, park it up and let it idle, it is perfectly 900rpm or there abouts.
Could anyone know what is going on or experienced a similar problem?
Battery is fine, alternator is fine. could it be throttle position sensor or AFM related? Could anyone please help?
