Erratic idle
Just like tittle says... Erratic idle... Any ideas? Little vibration when pressing on gas...
Anything will help. Jorge

I would do it like this. New Air filter,MAF spray in sensor and throttle body wile running. Intake boot must have both clamps. Check for sm 1/4 inch vacuum hose to pressure regulator at rear of fuel rail , they crack. Run a can Sea Foam 1/2 gas 1/2 engine. change oil and filter 50 miles later. If your plugs are over a year old check them for replacement. All this can be done for $60 or so and 2 hrs labor.
