yousef

 

sorry to hear that hmmm well i have to tell u unstable idle has nothing to do with the leak in the headers had leak for long time and idle was always stable check ur spark plugs

 

well it could be ,,, not sure about the plugs ...

i noticed that when i shift to 4th geer in full throttle the boost cut ... so i think maybe some leaks in boost controller wire in the vacuom behind the throttlebody ...

 

I'm sorry to hear that you're still having problems.

Surely, if you contact Dan at Vivid, he'll do everything in his power to help out.

It's his kit after all, isn't it?

 

Good call karim, he usually answer and replay very quick this time I don't see him around

 

Yousef and I have gone back and forth. We are doing everything we can. I did advise him to talk to Karim and yourself Yulmutawa about where you get your work done as a simple boost leak test is needed. It seems his past shops are not helping him. The car did not have idle issues before he took everything apart to add the NX spray kit. This involved removing the intercoolers and the secondary air pump line to the left side intake filter. When it is cold out, the idle is rough until it warms up, however he is not experiencing this.

Please perform a boost leak test first as seen here - https://www.6speedonline.com/forums/...ig-w-pics.html. Once this is done, it will help further determine the problem. I will do anything in my power to help you out brotha!

 

check for leaks on the Y-pipe and plenum

 

Well it will be an honor to help you guys with any thing u guys need m leaving to the states i'll pm u ysf my cell number

 

Please though, do the above boost leak test in that link. That is the first thing you MUST do or you are chasing a ghost.

 

thanks alot guys ...

dan the car is not leaking ...

i ran the car hardly daily its powerfull and i can feel the power ...

all what happend is after running hardly the idle revs alot !!!!

after 5 mins it became normal !!!!

if its a leak it will not became normal after mins !!!! maybe its the mafs or the throuttlle body !!!!

 

If the MAFs were bad, you would have a code and limp mode boost. If the TB was bad, you would have a code. You have any codes?

I've been through this kind of "idle hunting" issue with a few cars (it can be frustrating). It requires a number of steps of checking possible sources which also adds info for problem solving. Vividracing is an excellent tuner and they will work this out with you but you may have to have a bit of patience as it's not always a quick fix. If you have a code reader (if not get one - they are cheap) keep giving them the codes and symptoms as it could be a number of causes. Leaks, MAF, O2 sensors, bad gas, aliens (just kidding) etc. so just keep the codes that arise so the necessary detective work can be done. Your tuner is working with you - so work with them as they move toward resolving the problem for you.
Good luck - hope it is resolved sooner rather than later.

Just got my 996 back from the shop after 10 days of looking for the cause of an intermittent idling problem. They said they finally found the secondary air leak.

Car runs and idles great now. By the way, no codes were thrown in the entire process.

 

thnx for posting ,, do you have a pic for the leak place ??
