I have a 2004 mustang gt. Just started getting a p2196 bank 1 stuck rich. It's my girlfriends car. She said it acted like it was cutting out. I drove it and it's fine at idle and normal driving. She said it would usually do it right after she got on the highway. So I held it to the floor for a little bit and slowed to 70. It felt more like it was surging. I had my handheld and was datlogging the fuel trims. Bank one would be stuck rich. Bank two was still fine. After a few seconds bank 1 would go back to normal. The only thing I can think of Is an injector sticking open on bank one for a short time. How can you test for a sticking injector that only does it after a good pull? Is there a way I could use livelink to see an injector sticking? Will I just have to take it to Ford? I haven't had any luck with them. They were useless diagnosing my cobra.
