Having problems with your Chrysler Concorde ?

I keep getting a p0171 and p0175 codes from the scanner (auto x-ray)(meaning i'm lean in bank 1 and too rich in bank 2). fuel injector cleaner didn't help really help. so should i replace the upstream O2 senors or the fuel injectors... any other suggestions would be appreciated. thanks.

Answers :

P0171, p0175 = system too lean (usually related to MAF Sensor) this means that the Air Flow Sensor is telling the computer that much less air is entering the engine than actually is. but first check for vacuum leaks in hoses and also pcv hose. the maf sensor may just need cleaned. any auto parts store will have maf sensor spray, follow directions on can. or you can use electrical spray also. as for the 02 sensors its possible. check or clean maf sensor first.
