1998 3.8 V6
I tried doing a few searches but I can't seem to find an answer to my issue.
Ok so a while ago I get a check engine light and pulled codes P0135 and P0155, both upstream 02 sensors fault. Since I had to replace both the downstream sensors 6 months back I figured it was much the same.
So I replaced both of them and left my battery unhooked for five minutes before taking it out, then pulled 4 codes:
P0135, P0155 and I don't remember the other two (Said I was running lean)
Replaced my fuel filter (Def. needed it), Cleaned out my air filter and MAF, fuel injection cleaner, checked my fuel pressure (38 PSI) and checked for leaks (couldn't find any, unless I'm looking in the wrong place).
Got the check engine again but I figured I hadn't driven enough to complete the test (Work has a tendency to cut my car time short) so I drove it for another tank (Not at once). Light was still on, only pulled the P0135/155
codes.
Left the battery unhooked again then took it out for an hour and a half drive, light stayed off the entire time. Shut the car off, took care of my DPS stuff, then started the car back up. No light. Drove ten feet, light came back on.
Still pulling only the 135/155. Not sure it makes a difference but I'm using my girlfriends Actron ODB-II PocketScan to pull the codes.
My inspection is up next week and I'm really trying to figure this thing out. Any help is greatly appreciated
