2006 Honda Jazz 1.5L Automatic
I have an issue with my Honda Jazz when I come to a stop or press on my brakes hard the rpm drops below 500-400rpm and it feels like the engine would stall but it never does. I have since replaced my Sparkplugs and ignition coils with new ones as I thought this would fix the issue but it hasn't. Any idea what would cause this and any suggestions on what steps I could do next to try repair this issue? Thanks
It sounds like you may have a vacuum leak somewhere. Check especially the large vacuum line running from the intake manifold to the power brake booster.
