I think I may have a small vacuum leak. Lately my car has been idling around 1100-1000. Normally it would be around 800-900 when fully warmed. However, my car is running fine and the idle is steady, not jupmy at all. I researched and looked for popped off hoses but cannot find anything. Any ideas on how to find this leak?

 

hmm..i will use the force to sense the leak.

seriously though, need more info on your car like what mods you have. that could help in finding vulnerable leak spots. but best way is a boost leak tester. costs around 10-15$ to make. just need an air comressor

 

ima do a boost leak test tomorrow. i have a tbe, full synapse ic piping (upper and lower), synapse intake, and synapse dv. i went out today to look again and couldnt find anything.

 

I think the most common is prob the egr valve hoses...there are two...
