Low Revs When Car Is Stopped?

[tiesto]

ok i have seen another problem

my battery light is glowing/shining around idle 900/1000rpm perfect

but when i rev it to 2000 or more, battery light disappears

is this alternator? what could it be/

(tiesto has a battery light actually on his battery)

You may be right, the alternator could be causing a weak spark at low revs? keep trying things i guess

Jump start it with another car that is running if the problem goes away then your altenator is stuffed. What you usually find is that as the car goes to stall the alternator voltage gets very low and bring up the charge light. I dont think this will be your problem as the standard ECU will have very good corrections for battery voltage anyway.

I'm still suss on the TPS sensor and if you find thats fine then you really need to determine whether or not the ECU is driving the AAC valve and also if the vlave itself is actually operating. What happends if you disconnect the AAC valve and then start it?
