Hey guys...
Need some help. I did the DIY: spark plug change. No problem...Didn't really have to move a lot of things around. I unplugged 2 tube from the plenum, and the tube for the SAI. Changed out the plugs, reconnected everything...

Cold start up: Starts up fine...car runs like a beast
Warm start up: Doesn't stay on...car runs great after giving it some gas during start up.

Scott from Ballistic says I have a Vac leak...But I'm not really sure where my leak is coming from since I only pulled 3 tubes.

Any ideas??? Where to look for vac leak?

I couldn't get hold of the NGK plugs so I ended up getting Denzo plugs, gap the plugs at 1.1mm....(I saw that spec online somewhere)....

Please help....

 

Check your connection at the throttle body. Sounds like unmetered air coming in. MAF is in the main tube. If you are leaking at the TB it can stall out.

 

you also might of cracked a tube pulling them off, same happened to me. you can hear the leak.

 

If that doesnt work, try swapping to NGK iridiums.

 

best advice is that there should be 2 tubes on the plenum itself. Left side which is obvious, the other is on the back of the plenum where the throttle body connects. The other 2 that are on teh throttle body are for coolant and you would know if those were off the car. Then you have the actual intake tube hose. Other than that I dont know of any other VAC Leaks....

 

Yeah its kind of hard to spot the coolant one till its too late, i learned that one the hard way.

 

I have learned many of times..LOL!
