Does ST know cars? I'm hoping to troubleshoot this weird issue on my own. My car (150k miles, 5 years old Chevy Cruze) has a fair bit of hesitation

on acceleration, especially with the AC on. It is a little disconcerting when moving into traffic. One possible thing might be the MAF (Mass Air Flow) sensor though it does seem to be accompanied by a check engine light (which I do not have on)

However, it seems pretty easy thing to inspect/clean based on what I've seen online. I also had the car in for a tune up not so long ago so I would have expected that would have been part of that process along with new spark plugs (also a possible cause)

Thoughts?

Responses:

when they do tune up they 'check' the wires and in the process often break one. or maybe they have a couple switched? -- nm - zeitgeist Jul 26, 13:59
I've had acceleration issues when the catalytic converter died; it caused issues with exhaust pressure and made the vehicle useless on hills. - Beryllium Jul 26, 12:50
Do you have a turbo? -- nm - spamlet Jul 26, 12:49 2
- Good question. Looks to me like all the Cruze trims have a 1.4L turbocharged 4 cylinder -- nm - oblique Jul 26, 12:52 1
  - It could be the turbo has clogged. That happens on a lot of VWs around then. - spamlet Jul 26, 12:54
