RE: random misfire please help!!!
Dirty MAF sensor, carboned up EGR or IAC. Might be a dirty poppet valve sticking....try running Seafoam through tank, it might unstick the poppet valve, depending on the amount of carbon...
These items can be checked and fixed with a minimum of money...seafoam= $8-10. EGR cleaning cost of gasket, same for IAC cost of TB gasket if the old gasket becomes damaged...
