I have a 1997 ford contour 2.0 liter 4 cylinder 169,000 miles. I just had to have the water pump replaced at which time they also replaced the timing belt, accessory belt, changed the oil and oil filter. I have a check engine light on code says po171 too lean bank 1 that's been on for a while. Before the work was done, car idled fine, never stalled at lights, etc. Immediately after I picked up the car, started to idle very low (500), rough, died at lights, etc. Took it back, was told it wasn't anything they did, told me I needed to change my O2 sensors and basically treated me like a stupid woman and sent me on my way. Can you help? I need to fix this the most inexpensive way possible. Thanks so much.
