Default 4-6th Gear Hesitation - 03-04-2019, 08:24 AM

My car has developed a hesitation when accelerating in 4-6th gear. The JB4 has been fitted for a few thousand miles now with no issues. There are no codes showing either.

Any ideas?

When mine did that. The spark plugs were the cause.

Can't hurt to attach a JB4 log so we can check AFR and fuel pressure for you when it's coming up. But I'd guess plugs too.
