Hello all,

My car, 13’ R60, shows super tapping. This issue only happens in highway while acceleration. It happens no so often but do occur once in a while. I always fuel it with Shell nitro+. Do you guys have any idea what might be the issue that cause super tapping or potential things to check? Will that be the issue of HPFP?

 

A 2013 R60 shouldn’t have fuel pump issues, as it uses the more robust revised and updated design. If you are 100% sure it’s not bad gas, I would start with new plugs and coils.

 

I have 4 NGK iridium plugs and Bosch coils, ~ 8000 mi. Any thoughts?

 

x2 plugs and coils, this is the base starting point. While I don't remember a specific mileage number, I had a Bosch coil fail very prematurely. If money is tight, try to get it scanned and see if it is throwing a misfire code for a particular cylinder, and try just replacing on that one. Failing that but following the same principal, try a new plug and coil in each cylinder one at a time. It's unlikely, but hardly impossible, two went bad at the same time.

 

Thank you for the suggestion! No miss fires yet and any brand recommendations for coils? I don’t worry about how much they cost but just want to get it fixed

 

Most people on here seem to recommend Bosch for coils. I think my R60 currently has 3 Bosch and 1 Delphi in it. The 1 Delphi was an emergency buy from a local parts store when a Bosch one failed prematurely. Things happen, not throwing shade at Bosch.

EDIT: spark plug recommendations, I don't know. I happen to be running some NGK Iridiums that were around $90 for the set of 4 where I live.

 

I have had new plugs that turned out to bad, its frustrating and can lead you down a wild rabbit hole of diag. That is why now i save the original plugs number the boxes and set them aside and i also number my coils.
