Well guys I think I found my electrical issue, well suddenly my car was stalling randomly in a parking lot and when I restarted it it would only stay on for 3 seconds or so until it stalled or I hit the gas. Mike saved the day! Called mike and he told me to check the ground bolts near to the radiator cover, sure as hell the one on the left was so loose it was barely getting any contact to the body, after hand tightening this meanwhile the car started and ran fine all the way home, after messing with the bolt and tightening it I got check engine light p0443.


It was the one on the right, could this be my issue the whole time?

 

Likely answer, yes. I´d sand the bottom of them a bit, were this me, then locktite, then grease the outside of the suckers.

Many a car-fire has occurred due to bad grounding, resistance is the enemy! Be it rust, loose connections, etc..

 

Anyone know what the one on the right grounds? Im hearing fuel injectors which makes sense and from this ground losing and regaining contact could it have caused this code?

 

My first thought, since you´ve now checked the grounds is to just clear it, and see if it re-appears in short order. If it does and your electrical system isn´t being gremlin-ified anymore, then you´ve got something new to contend with.

 

Did you disconnect the ground and clean up all the mating surfaces or did you simply tighten it? If the later, corrosion may have formed between the mating surfaces and even tight it may not make good contact. I'd try that first and go from there.

 

I just tightened it down, I will go back and clean it up a little.

I have no idea how to read that.... Just tell me!

 

There is no easy answer...

 

Battery and alternator test are in order to start with. P0443 is a code set when the ECU doesn't see the correct pressure drop to vent fuel vapors from the charcoal canister, and the ECU has determined a likely fault with the valve that allows engine vacuum to pull vapors in for combustion. IF YOU ARE HAVING ELECTRICAL ISSUES, this could be a secondary symptom. How much did you guys touch under the hood while attempting the S/C install?

Sounds possible that something from the HIDs may be grounding out and killing power to the ECU and/or ignition coil pack. Or possibly causing a short in a lighting control ECU (if there is one on the car) and the ECU is shutting down to protect itself. Try unplugging all the HID stuff first and testing to see if your having stalling issues. Make sure EVERYTHING you guys touched has been properly reconnected.

If its still acting up.... take in to the pros and let them figure it out. Just try to eliminate things you had contact with first before you take it in. As a technician myself... I have charged people for stupidity. Not saying your stupid, but dont overlook the simple things. A tech that knows the product he's working on will spot things like that in a heartbeat. What takes us 5 minutes to fix will cost you an hour of labor for diagnosis and repair at a minimum.

Make sure your confidant that what your recently tinkered with is installed properly and/or everything is connected.

EDIT: Aftermarket electrical components can and do cause some of the WORST gremlins in the automotive world. HID kits in particular are among the worst offenders. As much fun as it is to upgrade your ride, the use of QUALITY components and kits will do wonders for not only your wallet but piece of mind. Factory stuff is expensive for a reason: all the parts are designed SPECIFICALLY for your car to OEM standards.

I guess what I mean to say is at the end of the day: caveat emptor
