i have a 90 xj laredo with the I6. i have replaced the TPS, IAC, fuel filter, cleaned my throttle body spotless, and yet i have a terrible sputtering problem in one particular range in the gas pedal. It is not rpm, speed, or gear related cause i've tried to make the problem happen to get a general idea of what's going on, but it is always in one particular range. Oh and if it is floored it will sometimes act like it wants to flood out. Anybody have any ideas????
