Turbo Problem ? Just got my Turbo T60-1 installed and tuned. Well the drive home went well. Got gas, went to see a friend, got back in the car after is was running in park for about a minute or 2 and the SES light was on. Went straight home with the light on. Now the car is idling very rough and bounces between 300-800 rpms. Fuel pressure is 62-64. I disconnected the battery twice for 10 minutes, but the light would not reset and it still idles rough in drive or reverse. Also, I noticed little black specs on my rear bumber and back of the car (while running in garage). Is this black soot normal? I am going back to the shop Monday to have the code checked, any ideas whats wrong? Also between 45-50mph the car felt rough. I have the turbotech t60-1 kit, Walbro 340 intank, 42lb injectos, 160 tstat, wideopen Borla, 3.73 gears. There are no cats, the 02 Sensors were shut of in the back 2 sensors, the EGR was removed and turned off, and the car was tuned with LS1 Edit. I am waiting to drive it anymore until I talk to the shop.
Re: Turbo Problem ? My guess is that you have an o2 code. low activity in your driverside front o2.
MIne does the exact same thing sometime.
Bounces down and up in idle when the the engine pulls the vacuum. Mine now is so bad it barley holds an idle, it will stall when you let out of the clutch and thottle
I think im getting closer to finding the problem, think its my injectors. DId you buy yours new or used, mine were used. either that or DSI tune needs to be tweaked, cant remember if when i brought mine back there it got better or not. But i do think its one bad injector, cause also im spitting out alot of fuel at idle, which gives off alot of black smoke at idle.

Re: Turbo Problem ? I'll talk to Greg tomorrow and try and figure it out. It's probably something stupid, but its a pain none the less. I just hope it won't be a recurring problem.

Re: Turbo Problem ? Just to let you know, it was a spark plug wire that came loose. It's fixed now and it's idling clean. No more light. So I am very happy now and pushing right around 400 rwhp. I don't think I am going to go beyong 7psi because I don't have the crank case problem right now and I don't want to cause it. At least not until I have money to go to 10+psi.
Re: Turbo Problem ? good to hear you got your problem resolved eaisly.
Ill have to go and check my plug wires just in case, but still thik its the bad injector.
What code did you get anyways.

Re: Turbo Problem ? According to what Greg said, you can burn a spark plug wire and sometimes not know it right away... I don't know the exact code though.... Greg and Phil had it on the lap top and fixed it in no time. Mine didn't burn the wire, it had just came loose.
