So, what it seems like so far is that a random injector will lose its signal. Last week I had a random misfire code. Found out it was injector number 2 not firing. Now today injector number 4 stopped working. I forgot to check the continuity on the injector itself while the issue is happening but the 12v signal is defiantly dropping in and out. I shut the car off and checked the resistor box and it checked fine on all pins. Restart the car and it runs perfect. Any ideas?
