computer troubles - 10/4/2003 9:43:32 PM    caza247   Posts: 2 Joined: 10/4/2003 From: United States Status: offline i have a '90 dakota with the 3.9 L V6. i have just put on the following: K&N stock size air filter, new conrad rotor and cap, bosch double silicone wires, bosch platinum plugs, and a new throttle position sensor. i had had troubles before with gas milage and decided to do a tune up and performance got no better, so i decided maybe the computer needed reset. i disconnected the battery for a half hour and now the thing sounds like crap. does anyone know of any little important steps i need to know of for reseting one of these things. also, i has a tbi injection system that is running very rich and i don't know why. thanx for any help.
