Hey can yall help me out here. I have a bad exhaust leak at the end of my down pipe due to a bad gasket. Im replacing that today. But since i got this leak my car is starting wierd and then going and turning off. Im throwing code 45 P0171 or P0172 which means in running ether too lean or too rich. Could this be due to the exhaust leak and the o2 sensors going crazy?? When im driving it runs fine and the a/f guage stays in the green (even though its not a completly accurate reading it gives you a idea). Do you think this is causing by the exhaust leak at the downpipe?? My idle is wierd also. THe car will start then jump up to about 2000 rpms then fall down to 500 then hop up to 900 or 1000 rpms and do this over and over till it shuts off. If i start moving and driving the car it is fine. It wont turn off at stop lights or anything like that. The a shop put in a FMU for me and this only started recently. I looked at my injectors today and they werent all the way back in. I called the shop up and they said they couldnt put them back in and they put washers on them instead. When i get home im going to fix that problem. Can anyone help me out??

 

are u turboed? if so, what kit?

 

put in the new gasket and take the battery off to restart ur ecu and hope for ther best... when i did my intake i got a CEL then i reset the ecu..... no more cell

 

The leak is now coming out of the dump tube. WTF. gonna look at that tonight. I looked at my fuel rail today and the bottoms of the injectors are burnt and one was completly off. Damn....i need new injectors. I hope no damage was done to the internals of the car.

 

I'm assuming your turbo if you are citing fuel needs.

 

Yes i am. Im using a custom kit. My car just got out of the shop getting a FMU put on it and the dummy's there didnt put the stock injectors back in right. They put 2 washers under each nut holding the fuel rail on so it sat higher. The injectors werent flush with the manifold of the car and there was only one seal on the top of the injector. the bottom seal by were the fuel comes out wasnt sealed at all. What im thinking is that when the car got hot, the hot air came up past the 1st seal and burt the injector ends. But it was still sealed since the 2nd seal was there but not all the way down. Im going to the shop today and im going to get them to fix the car. That was there fault and i hope they assume the responisiblity for it. I cant beleive after i put this whole turbo kit on myself they mess up the injectors...oh well....its going to get resolved today.

Can someone help me about the wastegate? It sounds like a open down pipe but its coming out of the dump tube. Mabye the waste gate is opening at idle from the vacuume lines. I can still boost so im not sure whats wrong with it.
