Ok so im having idling problems after i capped this vacuum port located on the back an front of the intake the car was tuned with them uncapped. but i thought i was loosing power lol so i capped them an when i did i noticed my cam gears were spinning alot slower an almost stalling the car out. So i turned up the idle a bit an now when i hit the gas the RPM'S fall alot lower anuff to where the car almost shuts off then they climb back up.the cars idle is at 900 i think but when i pump the brakes they start to climb up alot higher.. so my question is should i just unplug them?

 

bbuummppppsss for some help

 

With it unplugged wouldn't that be a boost leak?

 

i was thinking the same thing

 

When we started up my car for the first time, we had to create a vacuum leak to make it idle. We changed the IACV, tested continuity, and tested voltage. I took out the ECU and followed the traced in the ECU making sure the solder joints were good. It ended up being a bad ECU. You're not getting a CEL?

 

Adjust the iacv duty rate, or adjust the idle screw, or the TB plate.
Those ports shouldnt be left open. leave them capped and fix the problem.

 

My car hates my amplifier and head lights. Does the same ****

 

thankss will do
