my car idles (and holds)at a pulsation 650-900rpms.
I did the LCD tps thing still not much difference.
The problem was a combo of bad hoses a cracked gasket but the major problem was at the primary injectors the O rings and Gromments where all in bad shape.
now whenever I take a hard turn or put in reverse my car chokes out or idles dangerously low .
this also happens when my I press down on the clutch and brakes while in a turn.
I know this sounds like a bad BAC valve but it is not! I have two and both are good.
also I think this car has it's own custom made power steering pump. The previous owner had one made for her. and I think thats why my car orginial idled at 1000-12 rpms
I'm going to follow up and check out secoundary injectors.
I not expection a complete and ominous solution from anyone here. just some clues or a point in the right direction. This car is driving me up the wall and I need some ideas.

i think you're on the right track, but you should look at the backup switch, i'm not sure but the ecu might get that signal too
backup switch?
I managed to take it to a shop and one of the guys told me he adjusted the BAC valve. also he said if the problem remained he said I may need a new IAC switch. (I have no idea what a IAC switch is)
it works alittle better now. the idle doesn't bouce as much but it still chokes out on hard turn but not as often.
I'm I running in circles here or what?

excellent! thanks
Mechanics around here keep refering to a IAC (idle air control valve) which I belive is the BAC valve
I looked in my haynes manual and found nothing about it. I'm I wrong on this one?
I don't know what AFM means
ok I'll check out the fuel pump and swap out the O rings and grommets in the secondary injectors
thx again
