FIXED: Installed Edelbrock SC. Now car is throwing CELs
So I installed an Edelbrock SC last week and everything was going great until I started getting these CELs: P0171, P117B, and P1170. I've checked all the wiring for the injectors and they seem connected tightly and are clocked correctly as well.
I'm running the CARB tune from Edelbrock but I do have a catless Gruppe-S header (while waiting for my local tuner to give me an appointment for a custom tune). I'm not sure if that is making the system throw these codes. There's a chance its related by the looks of this thread (post #4): http://www.ft86club.com/forums/showthread.php?p=1618213 The only other thing I can think of is a bad battery (according to post #14 on this thread: http://www.ft86club.com/forums/showthread.php?p=2128963). I've had to jump my car several times over the last month, and have had it go completely dead about 3 to 4 times as well due to my fault but I've also fully charged it with nothing connected at least 2 times over the last week. These codes keep coming back though. I'm getting a new battery in a few hours to see if that fixes anything though. Interesting to note though: car still drives completely fine. I haven't smelled any gas or anything sitting in the car. CELs also don't happen while driving (after clearing it), and all 3 times it has happened I had just gotten into the car and turned it on and was idling waiting for things to warm up. Any idea on what this might be would be super appreciated EDIT: Went to buy a battery and monitored LTFT and STFT. LTFT was basically 40% any time I went near the throttle. STFT was mostly 0 but ranged between -5 to +11. I'm now leaning towards this tune really not liking the catless header. At idle, LTFT is 18.8 and STFT is 0.

Did you make sure every bolt is tight for the DI bracket? I would double check them

Sorry I'm not sure which bracket you're referring to. If you mean the entire fuel rail assembly with the injectors to the manifold, then yes. I torqued them down to 10 ft-lbs like the instruction manual said.

How is this a warranty or recall/tsb related issue?

If you're standing in front of the car, it's the black steel bracket that the direct injection ecu bolts to on the left side. I'm sure you were thorough, it's just something to double check as it's not an uncommon issue after having removed the intake plenum to install a supercharger

I double checked the bracket and it was tight. No movement at all. The connectors on the back were all also completely seated and locked in place.

I'm battling the exact same codes as you for the past 3 months. Tightened DI bracket and everything. I have the Sprintex SC though. Codes come back about 2-3 days of driving after clearing it.

Exhaust leak or a hose blown off of the intake manifold.

I don't know but a good test would be to reinstall the stock header. You have the ecutek tools, right?

I've emailed my local tuner to see if they can fit me in since I'm fairly certain it just needs to be custom tuned to compensate for the header but I'm not sure if they even do any tuning in the winter. |
