ive just noticed this today, started the car and it does the high idle cat warm up but it drops rpms and goes back. i was like ok must of had a blip and its fine. after work it does the same thing at start up. going to make a video if possible tomarrow. since car was low on gas 1/8 tank i drove over to gas station after work filled up and when started i was seeing if it do it again, but since it doesnt do the cat warm up it didnt do it. anyone had this happen? should i worry?

 

Mine will do that on occassion, It goes from 1.5k to about 1k-1.2k then back to 1.5k until its done. Never really paid any attention to it myself

 

Idle Surge? Sounds normal to me

 

welp just got a CEL for evap code P04 somthing YAY

 

Probably your purge solenoid going out.

 

whent in limp mode today on way to work, still only evap codes ??? called dealer and its going in tomarrow morn

 

yep purge solinoid cost of $170 to fix yay that make lets see here, like 1900-2000 dollars spent on it just in the past 2 months FML

 

$170?!? It's like a $35 part and it's right on top of the intake manny.

 

they had it and 170 is fine with me. atleast they didnt **** me with a broken caliper and a 200 dollar bill. if i would have know i would have done it my self
