rpms climb to 2k on start up?

**lrg8683** · 09-07-2008 09:19 PM

last night i had an intercooler hose pop off i was only going about 20-30 mph started accelerating and it went.. anyways.. i reconnected the pipe.. but now on startup the RPMS climb to 2k.. and it almost feels like they want to keep climbing.. then i hit the pedal and it settles down to 800.. anyone know what could cause this?

my car usually does that upon the first start up in the morning, then they drop after about 30 seconds

all the way to 2k though? i don't remember it going that high.

thats high for sure... im not sure why it would be affected after you blowing off a IC pipe though.... does it keep doing it? if so there are settings in VAG you can change your idle offset or whatever its called and it can be raised/lowered.

I have no clue but i'll shoot at it anyways. Does it still do that? I would try doing a throttle adaptation with the VAGCOM. maybe that will help

it was normal this morning when i left work, (about 1400-1500) and normal when i drove to class this morning.. so far so good i guess.

thats good.. if anything just call Marc, sometimes fine tuning can fix little things like that.

Why do our cars normally rev/idle a bit high (and then drop) when started cold? Is it just to get oil flowing?

This is normal for all cars. Ive never driven one that doesnt. It just makes sure that the car starts on the first try ex (getting enough fuel flowing ect).

it also helps the car warm up a bit before driving, ive heard your really not supposed to move it till the rpms drop upon a really cold start
