I know I had a similar problem when my disconnected, but it turned out to be a faulty Pressure sensor. Not sure if the pressure sensor got damaged after it was running without that pipe attached.
But that pipe puts in dirty air from the engine (sorry not sure of the techincal term) so if the ECU is running thinking the air is cleaner than it was, and now its not as clwan as it was, the ecu may have adapted, and not adapted back.
Maybe an idea to reset the ecu/disconnect the battery.
Only an idea though, wait for more experienced feedback, as I'm no expert on this area. |
