The equipment was not installed correctly, namely the tubes in the intake manifold were directed to the throttle valve and not to the cylinders, and their flute (air flow change valve) was healing in all channels, it didn't work like that, so I bought the car for 24 years under warranty, they referred to the air intake, fixed everything exactly did not work, removed the collector itself and I was convinced of the incorrect installation while I was sorting out the injectors stuck on them, I spent money on them. In general, I do not advise them. They do not want to eliminate their jambs. I also asked if you removed the collector before installation or not. They say yes, there is a flexible tube to look directly into the cylinders. I answer, so I answered, I bent all the tubes
