Engine Performance problem
1999 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 140000 miles
I have a re-occuring trouble code 171 bank 1 lean. I have replaced the exaust manifold because it was cracked, some of the vacuum lines (dry rotted) and the up stream O2 sensor. Could a clogged fuel filter give this code or maybe a bad fuel regulator?
