i have a ek with a obd1 gsr , and for some reason the car just started to bogg out , sometimes i cant go past 5500 rpm sometimes itll start to bogg out at 2500. no check light or anything. it threw a check code once and came out to be a code 30 but never came back . does any body know what could be making the car bogg.
also im running a obd2 type r ecu.
