Wires.

Anyway, I'll know on Thursday if the VSV fixes it. He's too booked up
tomorrow and since he charges me very little labor, if any, I have low
priority.

I just have to keep buying Toyotas since that's the vehicle he's most
familiar with. Toyota set up an automotive technical training program at
a local community college, and it's not only for new mechanics but
continuing education classes for existing mechanics as well. My mechanic
is nearing 60 years old and he still goes to those classes. Plus if he's
ever stumped on a problem he can call someone from Toyota and get free
advice.

What's your experience with after-market IAC valves? The current valve
has been removed and cleaned many times, and cleaning just isn't doing
it any more.

The new VSV appears to have fixed the EGR trouble code. By the time I
got out of there with the new VSV, Air Intake Hose, front and rear brake
jobs, oil change, and transmission oil change it was $450. All Toyota
OEM parts so it wasn't too outrageous, though it was my own oil filter.
The oil pan gasket appears to be leaking a bit but the mechanic said to
forget about it, that they all do that eventually and it wasn't worth
replacing on a 14 year old car.
