hey i have 2004 ba xr6 auto
its happen to me 4 times in the past 2 days
i slow down to a intersection and the its like it bogs it goes down to about 200rpm then 0 then 200 then engine dies
sometimes im at the lights its fluctuates between 200 and 900rpm
iv change spake plugs, fuel filter, and cleaned the throttle body with a rag and wax and grease remover
it hasn't died on me again yet but its has fluctuated between 200 and 900rpm

anyone know what it could be?

a guy in my trad school glass is resetting all the oxygen sensors with his laptop tomorrow

probably worth mentioning the air filter. Is it dirty.

the ba s we have here when that happens the wireing to the throttle body has a break in it but that is after about half a mill k

I have the same thing happen to mine every now and then.

It only happens after a good long drive.

When the engine does that, it hunts up and down from around 200-300rpm up to about 1000rpm. If I stab the throttle, it revs up, but continues hunting afterward. If I hold the brakes and apply a smidge of throttle it picks up and holds its revs.

The other thing I have done is turn the engine off, then re-start it. That always seems to fix it.

But what causes it in the first place, I don't know. It normally idles happily at around 800-850rom in Drive.

I haven't been able to trace the cause.

The same nonsense was recently happening to my BA, but I cleaned out the throttle body and unplugged the battery for about an hour, which seemed to fix alot more than what I expected.

Not too sure if it was from resetting the ECU or not, but after doing it, it idled at around 800rpm instead of 450, noticeably more responsive throttle and gear changes were silky smooth at speed and at a stand still.

I dont know how similar it would be to a problem i had in my EF

I had the exact same symptoms, it was a dodgy ISC that caused them
