GenVibe - Community for Pontiac Vibe Enthusiasts

Hey all. I used a Bluedriver pro to live scan my Vibe to try to determine the cause of an engine surge. Particularly while accelerating during a turn but sometimes also just going straight I'll get about a 3 second engine surge before it evens out. I know nothing of cars so I've no idea what to make of the results. I tried using chatgpt but thought asking actual people would make more sense of course. Can someone please look at these and see what you make of them? I'm not sure what to ask my mechanic to try next. I appreciate the help. The smoke test revealed nothing abnormal, o2 sensors were replaced, throttle body and mass airflow sensors cleaned yet still get a surge. I meant for the images to display in the opposite order they appear, sorry.

I'm not good enough to interpret the graphs

Does the engine surge cause an increase in power or acceleration, or does the engine speed jump up with no noticeable increase in output?

I suppose it could be a bad MAF. I don't know enough about smoke tests to say, but these older 1ZZ engines are likely to develop leaky intake manifold gaskets. The AI says a dirty injector might cause it, maybe try adding an injector cleaner to the tank. No idea the mechanics of why the surge happens more when turning that when going straight.

Sorry couldn't be of more use
