I had the same thing happen to me in third gear about 2 weeks ago, I have similar mods, but everything seems fine

Was driving car again today and seemed to be more frequent sometimes when cruising around 60mph like 2k rpms would hiccup for a sec when slight throttle applied. Was thinking of upgrading fuel pump and installing a bbk maf sensor?

I had a similar problem with mine last year. What I discovered was that the Anderson power pipe was heavy enough that it had pulled just far enough off of the intake. I think the slight surging/stalling that it caused would help to reseat the rubber connector enough to seal air off for a few more seconds to operate normally.

Dist. Is original, its not a misfire. Basically for a split second feels like it has no fuel or spark then all is fine. Happens maybe 2-3 times per 30 min drive. Did not do it all last year only mods done over winter were headers manual rack swap and got rid of charcoal canister and cruise. Canister line is capped and gas cap is vented style.
