What's the best course to correct high HC (ppm) on my 1997 Toyota Camry?
Can my mechanic correct emission failures? He just replaced an EECS Vent
Control Circuit code malfunction with a new Purge Valve Solenoid that cost me
a painful $435!
With 276K miles on my car, it still shows 77 ppm on HC. It can't pass Smog
with these readings.
