been dealing w/a random/no pattern hi rev issue that am still unable to resolve (see the hi rev post I did here earlier) and now have another issue...now, when on an Interstate, @ sustained 65-75 mph, my check engine light will come on, but will flash, instead of staying solid-usually meaning an issue that needs immediate attn...when i get her whoa'd down and safely off the road, or if i cant and have to keep driving, the check engine light w/stop flashing and remain solid...when I hook up my ODBII tool, the only code I get is a P300 random misfire, altho I dont notice any bucking, rough running, etc while i am on the Interstate...after I clear the code, this code and the ck engine light doesnt come on or happen under my normal driving around my area, only when I get back on an Interstate again, then repeats...doesnt happen even @ sustain'd 55mph 2 lane road driving..... plugs, wires, cap and rotor were all changed less than 1000 miles ago, and even had a garage verify my cap was correctly screwed on , and all my plugs wires inserted correctly and tight...thoughts/ideas?
