i notice lately that after putting my dak in park it will rev up to 1500 rpms and go back down for about 45 seconds or so. it isnt a big deal but at the same time im wondering why this is happening. Probably not an actual problem and just a result of one of my mods. Anyone else experience this? Also, completely random but does my picture show up in my signature? It doesnt show up on my computer so i wasnt sure

 

When was the last time you removed your throttle body and really cleaned it? Removal is very simple, if you need write up I will make one.

 

Also check your vacuum lines to ensure you don't have a leak.

 

do you have a fastman throttle body??

 

Mine does the same thing just not as long. I put it in park and it shoots up to like 1100-1200 RPM's and stays there five seconds and returns to normal. Hmmm...

 

no i dont have an aftermarket tb. when i installed the intake in january the tb was clean so i dont think thats the issue.
