Hiccup during maintaining highway speeds

Niko_X5M · 09-14-2020, 02:44 PM

I’m experiencing a hiccup when on the highway maintaining speed. I have a jb4, intake, downpipe, new chargepipe and exhaust. The hiccup is random and happens as I Maintain speed but only when at highway speeds Around 2k rpms. Anyone else have this issue and know what’s causing it?

Can you elaborate on what you mean by hiccup? Are you having some issues with maintaining RPMs or what?

Hey this happened to me recently. Whenever I was maintaining speed whether it was on the highway or road every 10 or 15 seconds it would feel like a hiccup on my '15 m235 FBO. I ran codes and realized the ambient temp sensor wasnt working and once I replaced that it ran perfectly after. I also noticed my valve cover gasket was leaking so i replaced that at the same time but I believe the issue was due to the temp gauge. My car would also stall when in reverse.

Never mind after some relaxed driving the hiccup is still there. OP, did you ever figure out the issue?
