Hey guys wondering if anyone expierenced your car having a miss a high rpm and what caused it? There is no check engine light on or anything runs good at low rpm with no miss until you get the rpms up around 5800-6200 then starts cutting out I was wondering if it could be bad gas possibly, your help would really be appreciated.

One of the things that can cause high rpm missing is bad spark plugs.
Thanks man I will check them!!
check gap, check for cracks in porcelain as well. any crack or dark spot and they should be replaced. Go with oem autolite, motorcraft, or ngk's in oem heat range if stock. If boosted, then do 1 heat range colder ngk's.
If you still can't figure it out, try doing a Crank Relearn with an x4 or ngauge.
This. I"m changing mine this weekend.
