oxygen sensor failure P0171 System too Lean (Bank 1) - Read Our Article On Oxygen Sensor Codes For Help With This Generic Check Engine Light Code P0174 System too Lean (Bank 2) - Read Our Article On Oxygen Sensor Codes For Help With This Generic Check Engine Light Code
hope this is a bit of a push in the right direction ...
If the code is p0410, it is the secondary air pump. It tends to fill
with condensation and fail. Replace the pump and check valves coming
off the manifold on either side of the engine. The driver's side check
valve seems to fail first and allows condensation to run down hose to
pump. Hope this helps.
sounds like seprate issues check for fuel pressure, and spark. the code refers to a poss bad o2 sensor wich would be a seprate issue since o2sensors typically wont keep it from starting, just use alot of gas. good luck
There are to many things to look for that cause the symptoms you described. Best thing to do is get it scanned for a DTC code, that's why your check engine light is on. Auto Zone scan's for free and most auto shop's now scan for around $10.00 to $15.00 since almost every shop has a scanner and want the business.
The scan is going to give you a miss fire code with other codes to why such as to the left or right side banks running lean or both running lean and may be a transmission code to why it shifted hard.
Good luck and keep me posted, as long as there is a engine management problem the transmission may not shift in to it's 4th gear and OD may not activate so take care not to burn out the transmission.
hi, ok I'm sure you tried alot of solutions, I think the ECU has governed the engine must have sensed a previous problem or its just a malfunction from a sensor, important sensor to check is the 'engine knock sensor' try disconnecting and reconnecting it or test with multimeter and compare all readings with a new engine knock sensor or disconnect and reconnect battery, the other way might be to reset the engine managment system, this however I dont know but your dealer can do this for you.
