fuse 47 does a lot.

no codes at all.

#47 is for o2 sensors, cam sensors, A/C, plus other things.

I think the next step is to change the cam sensor?

So did you reinstall fuse 47 and then unplug the passenger side cam sensor? It accelerated normally after that?

I'm surprised that the car didn't set a code after unplugging the cam sensor. The cam sensors are pretty cheap, so replacing it won't cost you much.

I'm still suspecting the alternator leaking ac current (ripple), which is throwing off your cam sensor. Unplugging it may cause it to default to a set table and temporarily cure your problem. I wish I knew what the computer does when it doesn't get the signal from the cam sensor.

we reinstalled the fuse, then unplugged driver side cam sensor, car drove badly.
The plugged driver side, and unplugged passenger side cam sensor, car drove perfectly fine.

we let the car idle for a while.

hope replacing the sensor solves it. We are going to the drag this Monday.

thanks

* UPDATE *

we put new cam sensors, but it didn't solve the problem.

car doesn't drive well with new passenger cam sensor plugged.
but runs very well with passenger cam sensor unplugged.

I would trace the pigtail going to the fuse box and also inspect the Pigtail and connection.

You should be working with a tuner that knows S197s.

I was afraid of that. This is very odd and I'm tempted to go out and unplug my passenger side sensor just to see if mine will run fine without it. I'm betting it won't.

Well it would seem that you have misfires with the sensor plugged in, but don't with it unplugged. I don't know enough about the Variable cam timing to know why it would act that way.

http://en.wikipedia.org/wiki/Variable_Cam_Timing

A little light reading about the VCT system.

Did you ever verify the coil on plugs were working? may I suggest swapping the cops from the passenger side to the drivers side, just to see if the car still drives well wit the passenger side cam position sensor unplugged, but the passenger side cops on the drivers side.

After googling your problem, I read that unplugging the cam sensor will cause the computer to fire the plugs twice for some reason, something about waste spark.

I'm just throwing crap out there now, I don't really have any other ideas, unless your passenger side cam is somehow 180 degrees out compared to the drivers side, which isn't possible, since you haven't removed the cams.

still didn't have time to check the coils.

So it was the alternator. Now it makes sense why unplugging the passenger side cam sensor fixed the problem. Well it didn't fix it, but it bypassed it.

strange not many have experienced the same issue. Only a couple of posts mentioned the code and the solution.
