My 99 Boxster is missing after first starting the car wile its still cold. If I let the car warm up it does fine... unless I just jump in it and take off. Then it never stops skipping even after it warms up. There are 2 codes on the car right now p1128 and p1130 but I don't know what those codes mean? And the other morning i didn't have time to let it warm up and started going down the road and the check engine light started flashing but went back to a steady glow... I don't have a clue. So far all I have tried is replacing the air filter. I just ordered a fuel filter but it hasn't come in yet. Any suggestions?
