I recently got cams and during cold starts/warm ups. the engine is pretty rough and jumpy. is that normal??

Btw they are HKS 264/272 cams. with AEM cam gears.

 

Mine is with GSC s2's in there.

But how cold does it really get in LA?

 

right now.. it gets down to the 50's in the morning.. pretty cold for me.

 

You lucky SOB hahah lol its hit 20's here in New York.. and even colder with the wind chill =(

 

I think you should be OK I have work's 269's and some mornings it's kinda jumpy for about a min or 2, then it go's away

 

Without tuning yes it's normal.

With some ECU adjustment those cams can idle great. I just worked out my idle with Kelford 272's - now it's awesome cold and hot.

 

Thanks for your input fellas.

 

Yeah its pretty normal

 

importjake.. seems to me like your are postwh0ring. LOL

 

I'm are postwh0ring?

Awesome

 

I just put the HKS 264/272's in my 03 and other than the obvious change in sound, the idle is fine and doesn't die at any temp. I'm here in San antonio so temps similar to where you are probably. I also put FIC 1050's in at the same time as the cams, set the injector scaling and voltage change, didn't change anything else and it starts and idles fine cold or hot. It is running rich at idle but I haven't tuned the fuel map yet except at the top end some.
