Measure the exhaust back pressure. Do you have an old O2 sensor? If so just break the ends off of it so that just the tube is left sticking thru the center. Install it in one of the O2 ports and hook a vacuum/pressure guage to it. Should read les than 1 psi at idle and no more than 3 to 4 psi at WOT.

2005 jeep grand cherokee Po204 205 175 174 138 158. Runs rough. Whats wrong?


PO204,205 are injector circuit malfunction,PO174 is a system lean code, PO175 is system rich code, PO138 is heated oxygen sensor bank1 sensor 2 circuit high voltage, PO158 is heated oxygen sensor bank2 sensor 2 circuit high voltage. This is a repair for your mechanic. When they fix the injector and o2 circuits the rich lean codes will also be repaired. Continued driving will ruin your catalytic converter. Good luck

My 1998 ford winstar is showing check engine light and the code is p0171 what that means


Check for a small hole in the right angle rubber hoses between the PCV valve and the motor. A hold in the hoses will give a false alarm indicating "lean bank1" and "lean bank2" on Fords and Lincolns and once you replace those faulty hoses or at least tape them up you can reset the codes at the parts store and it should not come back until you have holes in the hoses again. you can also keep driving the car and after numerous "successful trips" with no more codes, the engine light will eventually go off if you have corrected the problem.
