I was just wondering if these numbers are good? Car idles fine, but the other day it was acting really funny and wouldnt idle I had to keep my foot on the gas then it would finally idle on its own after a while. The car has done this to me a couple of times actually. I thought maybe it was a vacuum leak or soemthing but the vacuum numbers look good to me, I just wanted to get some advice, or assurance that it looks good numbers wise. btw, it has a mild streetport - stock injectors I think, upgraded fuel pump and FPR if that helps.

 

there's nothing obvious from that picture and there's no not enough other information there to say much. You would have to buy a Datalogit and post logs from the PFC of this problem occuring.

Your description is also really vague. Under what conditions does the idle stumble? On cold or hot start? Decelerating?

 

take some logs of the next time the situation arises.

 

Its Random kind of after a hard run SOMETIMES - not all the time. It will act like its going to die with an extremely lumpy idle at around 200 rpm's. After a while it levels out back to normal. But it's only happened about 3 times out of dozens and dozens of hard driving.

 

what are your settings under the rev/idle screen?
