headlights flicker and engined seemed to miss

does anyone have an idea what would cause my headlights to flicker and the engine also seemed to not be firing all the way( if that makes any sense) at around 6000-6500 rpms? I work 3rd shift so i do alot of night driving. Not real sure if the two have anything to do with each other but it all happpened at about the same time.

Sounds like an electrical issue.

Misfires could be the spark plugs not sparking.
Headlamps turning on and off could be the lack of power as well.

Have you checked to see if that "little black wire" has tension on it (on the negative lead)? It causes all sorts of issues.
It shouldn't have any tension on it at all. It caused my O/D light to kick on and my car to not start one time (and I don't even have O/D!).

What little black wire? I also dont remember this happening during the daylight with the lights off. Could an extra engine to frame ground and an extra alternator lead help? i have a zx2 escort outback. Could rob wires off it.

Before adding wires, have you really gone over your electrical system lately? Battery, alternator, cables, connections and alternator drive belt?

WHY DO YOU NEED TO CHECK YOUR ELECTRICAL SYSTEM & CONNECTIONS:
- Your car is controlled by a computer.
- Computers are very picky about operating voltages and the quality of the electrical power they receive (spikes, surges, etc.).
- Computers process input signals (digital & analog) and produce output signals (digital & analog). Input signals come from electrical sensors. Poor connections cause garbage input signals from the sensors. Computer axiom: GIGO (Garbage In Garbage Out). When the computer produces garbage output signals it can cause all sorts of issues (poor start, mis-fires, etc.) and the issues do not have to remain consistent.
- Moral: diagnosing almost any start/performance issue should start with checking the battery, alternator & electrical connections.

Good luck

This little black wire (the image resolution is rather large; But the site should automatically "resize" it in a thumbnail, so be warned!).



If you don't remember it happening during the daylight with the lights off:
You should thoroughly check it, by testing it out. Does it happen with the low-beams on or off? DRTLs? Side-marker lights? High-beams?
