go.to autozone and tell.them you need a diagnostic port jumper tool. should be free. if u have a chiltons get it out. you.stick.the.two.prongs in the a and b ports of diagnostic port and turn on key. dont start. it should flash 1 and then 3 flashes (1e) that means its in diagnostic mode. if i remember right it may do that 3 times. then it starts flashing trouble codes. for example-2 flashes then 4 flashes is 24 and so on. the book will have the codes and parts those codes represent. or hit autozone and.let them scan it. also try unhooking neg. batt. cable for 15 min. to reset ecu. sounds like a vacuum leak though to me
