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?
Could be a small vacume leak?
If you think it's tranny related, I would just change the fluid. Nice and easy and it will be smoother for it
Yeah I'm thinking tranny, due to the fact I can actually hear the load come off the engine when I put the trans into neutral, I guess I was wondering if its a known symptom of something (serious or not) that im unfamiliar with, I'll service the trans hopefully that'll help.
What's the best way to change the fluid without letting too much air sneak in?
don't worry about air getting in, I'd be more worried about spilling the fluid over the engine
Because i topped up my fluid and got the same intermittent idle as discussed above. I'm guessing it was because too much air got in?
Tried the PCM reset and if anything it made things worse, nearly completely stalled at one point during the 5 minute idling period!
Did you try the idle learn procedure?
Faulty TPS or coolant temp sensor.

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.

DONT GET MAD...GET EVEN
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
