Need some help -- car problem Hi Everyone,
This past week I am having some problems with my car that are progressively getting worse. I tuned the car with LS1 edit in the fall and the car ran perfectly all winter. Now it has begun to sputter, hesitate and stall when sitting at idle. You cannot give it much throttle before it sputters and falls on its face. I have not changed anything in the computer since the fall.
I have picked up the following DTC's:
P0171 Fuel Trim System Lean Bank 1
P0300 Engine Misfire
PO132 H02S Circuit High Voltage Bank 1 Sensor 1
Po138 H02S Circuit High Voltage Bak 1 Sensor 2
PO174 Fuel Trim System Lean Bank 2
There is no check engine light on.
What do you think could have failed to cause the above conditions. My best guess so far is the oxygen sensor have bit the dust but I am open to suggestions/advice.
Autotap shows a lot of misfires and very lean fuel trims.
