Ok so I just replaced the coolant temp sensor which fixed my check engine light problem but now I have a new one. I was driving down the road and all of a sudden when I put my clutch in the car would eaither die or die for a sec and then come back (I guess after it warmed up). It was really weird. I recently installed a Evo 3 16G but I drove 160 miles since then and didn't have this problem. All of a sudden it just came up. I checked the hoses for boost leak (since I took off the Upper IC hose to install the sensor) but it seemed tight and once the car starts back up it idles smooth and fine. It is weird. I noticed it I sit there and rev the engine the rpms shoot up and then when I let off the gas it sounds like there is a misfire or two. I don't know....

 

What bov are you using and are you venting or recirc.

 

1g recerc. I had this problem before and it was a boost leak but when it was a boost leak it would only die when I made boost and put the clutch in. Now I don't even have too.

 

Anyone?

 

Boost leak possibly?

 

well it's weird because it idles fine. And it only dies after it is warmed up (after the choke is off) I don't get it. Does anyone have ideas?

 

I say leak as well. You can make a tester faily easy so you can actually verify you dont have a leak. Becuase sometimes its not obvious

 

Ok I suppose that is what I will do today, thanks guys.

 

OK I tested the boost leak. There was no noise other than the noise of what I think was just air running through one of the valves. (it sounded like a propane tank) I thought it might be the intake manifold to head. I put water with soap on it but there were no bubbles. I really need your help guys. It is weird. The more boost I make the easier the car dies. Like if I only rev it to 2k it is ok but past 3 it tried to die. I don't get it.

 

Does it feal like your hitting fuel cut?.....like does it feal like your losing all power, then when you let off the gas, does it come back to normal?
