91 Octane

troubleshooting

hunting down issues while at wot in second gear. the vehicle pulls until 5k+rpm, where it then gains misfires in cyl 1 and 2. this issue has been happening from day one, potentially a vac leak somewhere in there. next step is bypassing the oil catch can and setting the pcv to run directly to intake. when misfires happened, a loud noise akin to a long beep would occur coming from the engine bay. the vac canisters are bypassed to reduce vac leak possibility. replaced spark plugs, coils, injectors.
