I have 2016 Chevrolet Cruze LT 4 cyl, and since the weather started turning warmer I've been using the AC sometimes. Since using the AC I have noticed several times, just randomly it would act like it was hesitating and then it started spitting and sputtering. Then I'd smell a foul smell like rotten eggs. Then along with the smell, I get the spit & sputtering and a squealing sound. Now when I start it up it likes rumbles and shakes after a few minutes, the first start up seems fine, but a few minutes not even 3 minutes later it starts rumbling and sputtering again. I'm afraid to drive it to have it tested for any codes, afraid I'll break down along side the highway. Any suggestions, I've been told that it's my whole engine. I really hope not, because I just purchased this vehicle from a dealership in October.

  • Get an OBD scanner, plug it in the OBD port and post the PTC codes, if you can. Anyway, the rotten eggs smell, along with the sputtering, is definitely too much gasoline getting inside the converter (misfire). – Al_ May 7 '18 at 17:58
  • The rotten egg smell is hydrogen sulfide. It may be due to sulfur in the fuel or it may be coming from the battery. – juhist May 7 '18 at 17:59
  • Oh, and the squealing sound is probably your belt slipping. Check the belt tension and the condition of the accessories driven by that belt. – juhist May 7 '18 at 18:02

    Thank you so much I will try these avenues. I'll let you know if this has helped any. – N. Morales May 7 '18 at 18:37

    @Bart The problem is, until he posts the results of an OBD scan (don't need to drive the car anywhere, many OBD scanners that show codes are available for cheap), we can't be sure if he's having a seizing AC compressor or a misfiring engine or anything else. – Al_ May 8 '18 at 8:02
