I think that mangled wire actually goes to the low oil pressure warning
switch. Check the connections to the O2 sensor and the Temp 2 sensor.
Both of these can cause the symptoms you describe.

Subject: Help W/ Grounds - Bucking and High Idle

Well,

She's started bucking again, worse than ever.  First
time the bucking started it seemed to start right when
the alternator was going bad.  Dijitool showed low
voltage - 10.0 - from battery when bucking started.
So I replaced the bushings which were completely shot,
and also fixed a mangled wire - that went to the (temp
sensor?) down by the push rods on the driver side.
Awesome, no bucking for over a month.

So she starts bucking again, this time not only at
highway speeds, but when ever the RPMs get up near
2700-3000.  Also high, erratic idle.  I looked at the
bushing again, they seemed VERY worn for 3000 miles.
Went ahead and replaced the entire alternator this
time (only 89 bucks!).

Still bucking.

Can someone point me in the direction of some specific
grounds I should check - ie where are the important
ones for the FI?  Other than just cleaning them up,
can I use the the volt meter to test the grounds?

Your dealing with an electircal moron here, so
elementary please!

Thanks,

Jeff
