I got a 92 4runner with a 3.0 V6. did a head gasket change, everything is good to the point were it will only stay running for a short bit. as soon as i give it gas it will die out or if it dont die out it will hold the position were i have the gas peddle then die. it diffently smells like it is running way rich but with it being fuel injected i dont know. with the mass air flow sensor pluged in, it will not start at all. Thanks for any help or ideas
