View Full Version : Random Misfire Code
09-30-2004, 05:41 PM
I have a 99 gt with 70,000 miles have been having this random misfire code for roughly a month. I have replaced all the ignition components and checked the fuel pressure. The previous owner never changed a single part on the car. I have in the last 10,000 miles changed plugs, fuel filter, pkug wires, ignition coils and ignition module. When i scan the brain it just says random misfire. I have no idea what to do next, if anyone has some advice, please let me know.

Try flushing the fuel injectors clean through the fuel rail system (with fuel injector cleaner that hooks directly to the fuel rail).

The weird thing about it is that when its wet outside it does it at all sorts of different rpms and speeds. When its a nice day out the ses light blinks after it shifts to the next gear from a high rpm shift.
Had the same promblem in my GT a little while ago. Its most def the Fuel injectors need a fluss

Same thing happen to my car. I was having a misfire in cylinder 1 and the car was running rough in the low rpms. I took it to the dealer and they told me the injectors were dirty. I would get the injectors clean and go from there.
