OK, so here we go....2003 Sahara, 4.0, manual, 63K miles
Check engine light comes on a couple months ago and it's P0121...throttle position sensor. Order one, replace it and all good...until yesterday.
Check engine light came on again yesterday and throwing the same code.
Both times it has come on the day after a 1+ hour trip on the interstate at 75 mph. I think it is running a little rougher than normal, but that could be my hieghtened sense of awareness due to the check engine light.
Anyone know if there is anything else that could be wrong that is causing this code or causing the TPS to go bad (other than the possibility of getting a bad TPS when I did the replacement)?
Any help would be much appreciated.
