has anyone installed a 60 mm RENIX Throttle Body on there 4.0?
i installed one and haveing issues, but not sure if it is becuse of the TB, i am recovering from a blown head gasket on a 89 XJ replaced the head after getting it cleaned up also installed a pacesetter header, and Ford ms 18lb injectors at the same time. so i dont know what the cause is have checked all sensors, seem ok played with the tps checked everything to be working egr ok, checked TDC and the timeing,
this is what it dose. idle ok, driving at idle or supper easy on pedal ok start hitting the gas gets slugish, starts sputtering and back fireing
stomp on it and after some sputtering and the RPMs get up there it inproves...
what i havent checked is fule pressure i have no gauge yet.
thinking i should put the old Throttle body back on and see if it is that,
any more ideas????:wow:
