The 95 Zetec only has one O2 sensor in the manifold. I bought a bottle of Lucas fuel system lubricant today. For $5.99 it's worth a shot.
Do you think I should ask for my $89 back? That "Fuel System Care" did squat. Feels like a waste. I'll more than likely go give him the gears this week. I can't stand it when you spend the money on something a get zero results.
