well my TPS is pretty much dead...im not getting any resistance...the insisde is just fried....i mean its a 95...understandable...so im getting a new one tommorow....i was gonna get my timing advanced to 15.5 as well while im there getting the part...will they do that for me or is that not emmission legal....what do ya'll think my timing probably is at at 220 000kms?? 12*???...15.5 should ride real nice no?? is it worth my time?

everyhting on the truck is stock and the timing probably never been adjusted by the previous owner
