VT Gen 3 intermittent low idle

[wassup353]

Yep tried the idle learn procedure as well straight afterwards like the guide says.

I'm going to reset the sensors first to see if that changes anything.

This idle problem literally happened the second after i added some more transmission fluid to the car. I don't know how but it seems that the tranny fluid was the cause?

Idles the same when the clutch is in and when it is out.

Ideas??

Sometimes when I pull up to a stop my engine sounds like its about to stall, it almost sounds like when you slow a manual right down with the brakes without pushing the clutch in (but its an auto), if i slip it into neutral the idle pops up to normal. It never actually stalls, and it only does it sometimes. Anyone come across anything like this before?

I had the same thing happen a few weeks ago - as i pulled up to a stop the revs would drop to about 200-300 and almost stall so i got my tuner to adjust the fuel trims and it
fixed it straight away.....

How clean is your throttle body/IAC?

I'm more leaning towards a vacuum hose, pretty sure behind the manifold it splits into 2 hoses, check there
