Ever since I installed new headlights, I keep leaning out. I brought it to a local speed shop and dyno/ a/f test and sure enough when my head lights were on it went from 12 a/f to 15 a/f, and when the high beams are on it leans out even more. if connfused the operators, they thought it was electrical. oh and when i turn on my blinker the car runs pig rich. I have an afc for tuning. I know this sounds stupind, and doenst make any since but can any one help me? and do you think NOS octane booster would help?

 

I know what you mean, with my windows down I can't get a stoich idle

 

I'm in pure shock. Never heard of a/f being altered by the headlights being on!

 

It logically has to be caused by the current draw... I'm picking bad ground somewhere.. with the blinker pulsing the power off and on must all be filtering through to your injection

 

How do you check if it is running lean or rich?

 

this is a joke right











if not then +

 

no joke! now when i put it in reverse it shoots flames. i cant drive it like this!

 

Are you running 100w, that happened to me a while back you need to upgrade your harness to bring the fuel back to stoich

 

this is a frist for me.....interesting!

 

are you sure you have enough blinker fluid in the car?

 

Muffler Bearing grease, just dab it on, you'll run 9's

 

Too much load on the alternator. Add new grounds and clean the old ones. What shape is hte batt in? Go get the batt and alternator tested at Autozone for free.

 

Find a seperate power source and ground for your A/F controller. A direct line to your Battery with some nice new wire will probably stop that from happening.

As soon as I saw this post I thought, "Man I need to ask this guy if he checked his blinker fluid..." you beat me to it. But seriously yeah something is pulling enough current to either cause your fuel injectors to not put out as much as they should or maybe throw your sensors off. No idea though I'm just guessing

 

Cool! How do I do this mod? Got a write-up?

 

I can see that you will get optimum afr with the right combination of headlights, right blinker, stereo volume and dome light.

 

maybe this is why Im having starting problems
