My 1998 D1 recently began to stall out or loose its idle if stopped at a stop sign or traffic light. If it is a short stop my idle drops to almost nothing. Once I apply the gas pedal it takes a while (3-5 seconds) for the vehicle to react and accelerate. If I sit to long it stalls out. Once running it runs fine with no lose of power. My codes prior to the issue were 1313 and 1314. I just recently picked up 1187. Would this o2 sensor code cause this significant of a problem so quickly?
