not sure if this is a big deal but my car keeps sputtering at idle. It will just kind of sputter sputter and maybe drop 50 rpms(not 500, just 50). nothing intense I was just thinking spark plugs. any ideas? a/f ratio at idle is 14.0 off my plx wideband, should I even worry about this?

 

bump it up

 

Are you turbo'd?
Do you have bigger injectors ?
Whats your setup?

Sputtering is prolly not a big deal.

Let's see...

I would first check your plugs, rotor, cap, and wires. If those look good, then do a compression test, uneven compression can cause a sputtering idle.

If your ignition components look good and you have good compression, then I wouldn't worry about it. Maybe pull a little fuel so you aren't idleing at 14.0 AFR.

What is your idle set to anyways?

yeah I'm turbo, injetors are 750cc's
walbro 255lph, golden eagle fuel rail, sx fpr on 50psi
aem pems 30-1020 tuned boost comp, closed loop

idle is set to 1500 r's
also I was under the impression a/f for idle should be 13.7
