truck was having trouble starting from time to time. I then replaced distibutor with a the one i bought in Problem solved, exept now i have a SES light, and OBD2 code says random cylinder misfire. Truck seems to be running fine, except its getting horrible fuel mileage. i have replaced cap, plugs, wires, rotor, spider injection system and injectors (about 5k miles ago). I`m lost.. Anyone have any insight?? Thanks.
