How many miles on your cube? And any like hesitation or noise coming out of your exhaust
110K and exhaust sounds fine. On occasion right at start up there’s a brief hesitation (or feels like a misfire) but goes to normal idle quickly. I did install new plugs and new ignition coils last weekend. After that the start up was strong. The old plugs only had 20K on them but looked like they were burning hot. The white ceramic was yellowed around the edges. The ignition coils looked fine but I replaced them as well.
At over 100k I know that ignition coils should be replaced, you cant tell visibly if theyre bad or not from all the research I did, So Im pretty sure the ignition coild must have gone bad, My 2010 cube had over 100K and I started having misfire check engine light when i used a scan tool. The plugs only had about 10k When I replaced them but looked burned out. So I replaced mine with hitachi coils which are used in most japanese cars as OEM and also Denso uridium plugs which are the OEM Plugs used on a cube. All problems were solved after that,
I went ahead and changed coils and plugs. Keep in mind I did this 25K miles ago. The coils looked fine but they were bought from eBay. I have a suspicion that they were fakes NGK’s because the replacements were bought from Jegs (same part number) and the badging and even the quality seems a world apart.
Ya I will never buy certain parts on ebay ever again, I had bought some oem denso iridium spark plugs on ebay and they only lasted 10k. I had read that lot of
I actually think the Denso plugs that I bought off eBay were fakes too! They looked bad, way worse than the original plugs I replaced at 80K. The new plugs were bought from Jegs too.
I bought new denso plugs from autozone and got hitachi ignition coils, just the plugs alone cost me almost $80 but at least they were genuine, the cube drives like a dream after
