      Unhappy Intermittently Loses All Power While Driving ['09 Pontiac Wave]

      Hey all, I've got a 2009 Pontiac Wave, ~213k kms, manual transmission.

      Here's the issue: While driving it will suddenly lose pretty much all acceleration power and start to slow down (it has enough to get it moving from a stop without stalling but just barely). When this happens it will idle EXTREMELY rough at about 1200rpm in neutral.

      Now the strange part: To fix it I will pull over, turn the engine off, and wait two or three minutes. Once I turn the car back on it seems to run and drive perfectly fine (until the issue happens again).

      The issue started out happening every ~50km of driving, but has now gotten to the point where I will no longer take it on the highway and just drive on small streets around town.

      The codes currently on the car are the dreaded P2135 as well as P0599 (not worried about thermostat just didn't feel like replacing). The throttle body was just replaced back in August of 2018 (~8mo ago).

      Any advice or troubleshooting tips would be appreciated. I'm getting a new car but would like to try and keep this guy operational for long enough to spend some time searching.

      Thanks!

      Hi all,

      Sounds very similar to what happened to me when the coil pack failed. Is the coil pack original? Or has it been replaced at some point? I have had one coil pack on one 2009 Aveo fail at 5,000km. I had another coil pack on a different 2009 Aveo fail at about 120,000km. When it starts failing, the engine can barely develop enough power to move the car. So that's my guess. But i'd like to hear some other opinions.

      I also had the coil pack go out around 100k mi/160k km and it definitely killed the acceleration and made it idle extremely rough like you're saying. But two things stand out as being different here than for me. For one, that also gave me a misfire code. I replaced the spark plugs first and still had the issue, including misfire code. All went away when I replaced the coil pack. Secondly, it started abruptly and no amount of turning the car off and waiting fixed it for any amount of time. All problems stayed until I replaced the coil pack a day or two later. Not sure if those two things mean it's not the coil pack for you, but they stand out as being different to me.

      Hey guys thanks for the suggestions about the coil pack. Not sure if it's ever been replaced on this vehicle as I'm not the original owner.

      Not much of a gearhead myself so I'll do some research to see if a faulty coil pack can match the symptoms I'm experiencing. The strange part for me is how it's an intermittent issue. I'm not sure how to properly diagnose an issue that is solved by restarting the car and has no relevant codes.
