what is the normal idle rpm for a 3.8 becuase i get and even 1000 and i think that might indicate my vacuum leak if there is one

 

Not sure on the exact factory setting but it should be lower some where in the 500-600 range i would think.

 

mine idles around 800 if that helps any.

 

yea so if mine idles at exactly at 1000 and i get a p0102 code while experiencing stalling while slowing down and buckling when over 3000 after my cars warmed up would u think that it could be a vacuum leak?

 

HPTuners idle table shows 725 for when you are at normal engine temperature. Calls for anywhere from 925-1188 when first started depending on whether you are in park/neutral or drive.

 

By the way, the code you are getting is Mass Air Flow (MAF) Sensor Circuit Low Frequency. Basically your MAF uses Frequency signals to tell your computer how much air is coming in. Not sure what exactly the code is for, but my guess would be that for the RPMs you are at, your MAF is disagreeing with what it is reading and what should be coming in. Like I said, not sure about that, but that is my educated guess. This would support your vacuum leak idea.

 

i replaced the maf its not the maf

 

I didn't say it was the MAF. I merely said I think your MAF is NOT seeing ALL the air that is coming in. Thus supporting your theory of a vacuum leak... Read what I said, not what you think I said.

 

my bad all i need to do now is go out and get some starter fluid and find the leak THANX
