Mechanical, Exhaust & Performance/Tuning
To explain the title, I have a corsa B (x reg club 16v).
What is happening is:
-in 5th gear at 60mph car judders for a while and won't accelerate over 60.
-in 4th gear at just under 50 car judders a bit but for less time than above.
I put it on diags, no errors, just had new air flow...
