  1. Gen2 Diesel General Discussion
    Looking for some help with my 2017 Cruze td. During the first start of the day or whenever it’s sat for several hours, the rpms stumble 1-3 times for a couple seconds and then catches itself. It’s done it since I got it with 40’000kms. The problem goes away and it runs perfectly after that...

It holds boost above 10 PSI consistently, and if it needs 10 PSI again a few seconds later, it does not stumble. RPM doesn't matter, only 10 PSI. Also, if I gradually build boost, I don't get that stumble...
