Thread: keep killing #4 injector...

my car is a murderer and has killed 2 370's both #4 theres a signal at the plug not sure whats going on and i really dont want to install my new tomei's without figuring out whats going on. I have a replacement im going to swap in the morning. Just looking ideas...

could be a bad injector driver in the ECU, have you tried swapping ECU?

what signal is at the plug? should have simple voltage and ground. A node might tell you something. Car running really rich??

that's not the injector you're using for your rpm signal is it?

The car has been running just fine. I have a calum realtime swapping ecu's isnt that simple. i will have to check on that injector signal, im using a stepdown harness that has pigtails for my apexi units wired in. i picked up another 370 im going to swap in tomorrow.
