Hey guys, it's been a while since I had to come here for help on issues cause my car has been running great until now! I have a sort of rough idle and whenever I drive I sometimes lose acceleration power completely for a few seconds and I have to push the gas harder to get acceleration going again. Engine is throwing me and every shop I go to (been to 3 different ones) P0401 EGR valve code. I have replaced the EGR valve twice, along with cat and O2 sensors. The first EGR valve I bought I thought was bad, since the issue persisted after I installed it, so I bought another brand new and still having the issue. The code also says that it could be a blocked line that leads to the EGR valve, so I took off all of the lines I could see and sprayed air through them and they all seem fine. I don't know what else could be the problem! Help!
