Has anyone had an injector burn out from running too high of a duty cycle for too long?
My 94 5.0 has stock injectors, but are pushing their limits. At 300 engine hp they'd be running at 100% duty cycle. I've heard that running injectors at 100% for too long can overheat/burn out the injector. Has anyone ever had that happen in the real world?
My 5.0 is anywhere between 280-300 engine hp, and I've run it at wide open a lot. I've got the car back on the road after a bit of hibernation and cleared out a bunch of issues, but did a cylinder balance test and two cylinders came back as errors. One cylinder I knew would come back bad - the spark plug after a week looked almost exactly like it did when it was new, but not wet with gas or anything. After the balance test I put a stethoscope to the injector and it's not making any noise. I'm just curious if this is just a random failure, or if it can be attributed to pushing the injectors to the limits?
I still need to look at the other cylinder that came up bad, I already did comp check and it was fine, and that injector made noise, but sounded a little akward. It's nice that when you have 1 dead cylinder and 1 maybe dead cylinder the car still kicks the tires out from a rolling start :headbang:
I've got a set of used 24ibs injectors I need to clean up and throw in there. Just gotta find my injector cleaning setup. I took an extra fuel rail assembly, and drilled pieces of wood to hold the other end of the injectors. Then set up a fuel pump in a bucket of fuel injector cleaner, and a pigtail for the injectors to pulse them. Ran them to clean them, and check the spray pattern.
