hi i am new here to club x. i have read lots of repair threads and you seem to come up a lot with answers so...straight to the source yeah? please help. we just replaced the distributor in my 2000 xterra - had to unplug the tps to get to the distributor. we have adjusted the timing but we are still having problems. pulled error code p1075 TPS circuit A. it is running crazy. it will not shift at the appropriate times....especially over 45-50 miles an hour....the rpms just keep getting higher and higher. what should we do next??? could it really be the tps sensor...if not then what? thanks so much!
