Hey everyone I have a 2006 Ion with the 2.4L ecotec.

I'm almost certain I have a vacuum leak rough idle, hesitation in acceleration, reduced fuel economy. So my issue is I've tried to hunt down this leak with carb cleaner; but I'm not certain I've checked everywhere I should.

Does anyone have the knowledge or a diagram where the vacuum lines into the engine are on this model?

Thanks,

I have a 2007 with the 2.4L. It's been great so I never look at it. I have the AlldataDIY subscription. I don't see much in the way of vacuum hoses. Here are the only two diagrams I found. There are quite a few more vacuum lines on the 2.0L.

for the 2.4 ecotecs ive read ppl having issues with the fuel injectors getting clogged/seized. you might want to check those out as well if you cant find a vaccum leak
