Alright so I was having a leaning out issue and I have found the problem.
I plugged up a voltmeter to the battery as I drove around.
My car runs good at 13.5v, any less than 13.3v and the car begins to lean. I suppose the injectors arent getting enough power (I have already done everything else, no leaks,tps, blah blah)

I noticed the problem one night where I had a voltage drop and had my headlights on. I was at 13.1v and it was leaning. I turn the lights off and rose to 13.5v and it stopped leaning.

I notice I have voltage drop whenever I hit a bump in the road.
The battery is good with 12.6v and all connectors are secure.

The strange part is when I have my foot on the brake, I notice my dash lights turn and the H/L RET down clicks...Thought this was for the headlights.
I feel I have the big voltage drop due to this.
I feel somewhere between these circuits it is being crossed somewhere.

any input?
