My car has the line from turbo to wga.. The 3 solenoids are plugged in and just tucked under headlight housing, car runs bad at idle. Dealer says vacuum leak. Do i need to cap all the nipples on all 3 solenoids? or unplug them and do the resistor thing? Im an 04 so stock is stage one, should i just hookem all back up.....need help?

Sounds like TPS or something wrong with your Map/Tip sensor wiring. Most likely the TPS since it's a common problem.

A vacuum leak and a boost leak are not exactly the same thing. Depending upon the location of the leak and the conditions under which the leak presents itself. Tho, they are not mutually exclusive, a boost leak can also be a vac leak and vise versa.

When the dealership said "vacuum" leak the probably meant a leak in you IM gasket or something like that.

To locate vac leaks take a spray bottle of water and spray some H2O around the IM gasket and injectors while the motor is idling. Any water sucked in through said vac leak will cause a momentary stumble in idle.

To locate boost leaks you would use soapy water and look for bubbles while the system is charged and engine is turned off.

I only have Injen Intake and AGP WGA. The car runs bad at idle, but runs and boosts fine while driving. Im running lean too....So what should I do about the solenoids 1st, secondly what about my idlin.....

also guys, when i reset the pcm (unhooking the batter) the car runs good for about 10 minutes then starts this idling shit...could it be a sensor since it takes a few minutes to adjust???
