Full Throttle Hiccup

Full throttle, right at high rpm before the shift point, the car has a little hiccup. During that hiccup I spiked at 12* KR!!!!! Wtffffff. The little hiccup is intermittent and during the times at full throttle it doesn't hiccup, KR only comes up to about 2 or 3*. What the hell, any ideas?
 


My buddy ssei has this issue, hiccups wot high rpms.. Has changed plugs,wires, fuel filter.. Still has hiccups
 
What exactly do you mean Bill? I have an Interceptor gauge. That's as close to a scanner that I have. My buddy as a Snap On I could get, what exactly would I be scanning for?
 


Need something that can record what's going on during the hiccup. If the snap on scanner has live data which it should...you may be able to record while you do a quick run.

Knock, O2 readings, injector pulse, MAP and MAF readings all should show up.
