I know this is a common one, but I have a very specific result when the car trips PO300 code.
Info: Car is a 95 Talon TSI AWD. Has a 6 bolt swap with the 1g long wire CAS, 14b turbo, eprom ECU. Basically all stock setup just a mutt.
The issue: Car runs great. I use it as a DD. Because of traffic, I drive the back roads in the morning and highway in the evening when I come home. First thing in the morning about 10 miles down the road about the same place it drops the number 3 injector and throws a PO300 code. On the way home I'll be cruising down the highway and again at the same spot it will throw the code and drop #3 injector. If I plug in my pocket scanner while driving and clear the code, shut the car off and back on again real quick it will run fine all day long without issue no matter what kind of driving I do, highway, traffic or in town. If I just shut the car off and on again it will run ok for a little bit then randomly drop the injector (with engine light still on). Only with that combo of clear code shut off and back on does it run fine the rest of the drive.
What I checked: Plugs and wires are new, o2 sensors new, transistor pack bench tests good, compression good, boost leak check to 40 psi good. New walbro 255 pump, new filter, timing set to 5 BTDC.
I'm stumped on this one, the car runs great, but every day to and from work like a clock it throws this code and the #3 injector stops firing or visa versa., no signal at the pigtail. I just don't get the injector dropping out and throwing that code. Then when I clear it it can drive coast to coast without issue. And I can stop and get a sandwich and it will still be ok, it's like once it had a few miles to wake up and get over this code it can go all day.
Any thoughts on what's killing signal to the injector and throwing the PO300 code?
