Question? Has anyone had problems with the idle in neutral running rough?
i have noticed when i'm just sitting at idle the rpm's go below 750 and the car seems to spudder. anyone else have a problem like this? is my idle to low?
only had car three weeks. i did put on the
CAI/grounding kit . i don't believe it could be that. right? help

 

Another person had this problem some time back and took their car to the dealer. Turned out to be a misfiring injector and had it replaced.

Take it in and have them check it out.

 

I get the same every now and then.

They're like that from factory.. I think some tuning done locally on the fuel/air ratio will solve the problem, perhaps.

 

thanks for yor quick responses.
i'm on the phone with the dealer now
making appt's for idle/window streaks/
rim defect... caio for now

 

I have not had the problem as yet

 

I had the same exact problem from day 1. I was starting to suspect worn valves, leaky guides, grounding and what not.

Took it to the dealer, said my idle was set too low by 100rpm, reset it to 750. Rough idling is completely gone now. But I also swapped out the fluids with Redline at the same time, so I can't be sure if what the dealer did was what cured it, but now idle is now pegged at 750 with no sign of sputter whatsoever. Hope this helps.

 

Thanks yes that does help i will get them to look at it. then will be changing to redline soooon.........
