Is it possible to adjust the mixture somewhere?



The car will also NOT start when it is hot under any circumstances, starts right back up after 1/2 hour or so. Please help.

Fixing your idle mixture is possible. Any other time, its a function of the ECU.



idle mix is a function of the Variable Resistor, Air mix screw (bac).
