First, the car is a 2003 model with a 5 or 6 speed whatever it is they came with.

The car runs and drives perfectly under normal operation. However, if you are accelerating at all and have either of the blinkers on the throttle cuts out with each pulse of the blinker. My initial thought was that it the flasher circuit was somehow pulling voltage from the throttle by wire crap (yes, it's crap, on any car). However, I had him free rev it to 3k while parked and then turn on the blinker, nothing, so I'm kind of moving away from the throttle by wire idea.

So... I now would think it has something to do with the VSS sensor, but I'm not sure how the two would be connected and if that really even makes sense seeing as how it will maintain speed fine and cruise control still works. HELP please. Apparently this isn't the first time this has happened to people from what I see on the forums.

Later...

Installed a grounding kit just out of... I dunno... desperation. No change. Car only does this under load but at any rpm with the blinker on. Under idle and free rev conditions blinker has no effect. Problem started with incandescent bulbs and continued after LED's. I'm stumped.

Test the battery and check the grounding wire from the battery to the block for internal corrosion that can cause resistance. Just a thought.

Did that first... both are fine and installed an additional grounding kit... still no dice.

What about the fuel pump?

It happened with the stock bulbs. Started happening with the OEM bulbs in place.

Thought about that too, fuel pump seems to be functioning ok and voltage to the pump has been verified with a multimeter and as far as we can test doesn't fluctuate.

Why didn't I think of that?!? The reason for the 5 or 6 speed statement, it's not my car, it's my buddy's and I forgot what they came with when I first wrote the thread on a different forum. Also, I know I should get used to it... I just don't want to.

Anyways, back to the topic at hand... I don't usually get stumped with car problems... this one keeps me guessing.
