Chevrolet Corsica Forum : “sperattic hesitation misfire”

sperattic hesitation misfire

car runs fine when cold, after around 10 mins oil pressure is low, hovers at 500 rpm roughly at idle pulses or jerks with accelartion worsens with length of drive. hates 70kmh tends to shutter hard and jerk, im thinkin an injnector, or bad plugs/wire cap etc. haven't really dug in to it yet, car is new to me, thought maybe this might be a common issue with these cars. any input would be most appreciated.
