Hi everyone,
I installed my Supermax LT's today. With those, I replaced the stock plugs with NGK TR6's (Future NX Kit) and MSD wires. Awhile back I put in a Haltech Stinger intake system. The 01 Z06 is stock other than that.
Now, upon crank up and test, the car was sputtering and wanting to stall. Idle RPM is around 400. I at first read only a P0301 (#1 cylinder missfire) code. I replaced the plug with a new one, and wire just in case. Later it read a P0174 (Bank to lean, Bank 2) code. My question is, could the Haltech, plus the LT's lean the car that far out to where even idle is affected?
The car was dynoed several months ago stock, and in the low RPM's the car was very rich. By the time it hit high RPM's the car was way to lean. I knew I needed Edit, and was going to get it after the headers. But didn't expect even the idle to be affected like this.
Something that occured during the install was, I impacted the braided fuel line with the header when putting it in. It kinda crimped it. I took a pair of plyers and carefully brought it back to shape. IMO, I could see how a small crimp could eat horsepower up high, but can't see it at idle.
So, there's my story, can anyone shed a little light. Also, I intend on replacing the fuel line. How do you get the stock braided line off. Looks like it takes a special tool.
Any and all help is appreciated.
TIA.
