Idle issue Search didn't help me... maybe you can!

[CWJameson]

I got my 2.80 upper and dynotune yesterday

I got the car home and i noticed a slight

blump or pop every 3-4 seconds in the idle

i have ngk tr6 gapped at .30 (Tuner said so)

car has 77,000 on the clock

is there a way to mechanically raise the idle a hair?

i think maybe its idling to low

my tuner said that my engine computer code is the one that has problems with idling ? but we didn't see any issues until i got home...

What's it idle with the AC off?
Does it get better with the AC on?
Does it get better when you give it a little more gas?
Do you have a handheld tuner?

post up answers the the questions in the post above.

The idle is controlled in the tune, sometimes just having the tuner bump up the idle rpms up can fix the issue. Idle is also affected by MAF, settings for which are also in the tune.

AC off idle is like 700
ac on it goes to around 800
yes it gets better around 800
yes my hand held doesn't seem to have the ability to modify my idle range...

its a sct xcal2

This might help...I believe you can reset the TPS...

IIRC, You should be able to change you idle with the Xcal2

 

[VincodeY]

you can change the idle with the xcal 2

were is the stop screw on the 3/4 cobras?

 

[CWJameson]

How? i think mine is locked out of that stuff

 

[CWJameson]

kk figured it out

set nuetral idle to 850

up from 800

gonna let it idle for 10 minutes

can i turn traction control off with the sct xcal?

 

[Jomo1994z71]

Yes, you can...

 

[Jomo1994z71]

can i turn traction control off with the sct xcal?

Yeah, it should be right under the idle settings or close by...I left mine on...I don't mind hittin' the button, lol...is it idling better?

 

[CWJameson]

i don't see it
i went through...

nothing refering to traction

buncha stuff like spark global then 0-2000 4-6 6-8 then axle ratio... and idle drive and idle nue
and speed limit and couple of other things
but i dont see traction

im trying idle at 700 800 and 850

it always seem to be there

its not a big problem

its just every 3-4 seconds u hear a very minor bloop or bump

that normal?

My guess is that one of your plugs might be bad...I ran the copper TR6s for a while and just switched to the Tr7IX Iridiums which have a smoother idle...but my Tr6s never had too rough of an idle to begin with...
