Last Week my truck started to have a real bad stumble at idle. It would loose 300 or 400 Rpms and then pick back up. It seemed to run fine above idle. I was out of town and took it to a dealer and they hooked it up. The check engine light had come on by then. It had set codes on four sensors the Tech. said. They were all positon sensors, Crank, Cam,fuel pump and ?. He cleared the codes and the Crank position sensor imeditaly re-coded. He told me that the crank sensor was bad, and it could send a false signal and cause the other sensors to code. They replaced the Crank sensor and it no longer stumples bad, but it is not idleing real smooth either. I noticed I have a leak at an injector line, problably a cross over tube. Any suggestion on the poor idle?????
