Injector help
An anyone help me I've been reading threads but haven't found my true answer yet. I have a 92 XJ 4.0 4x4 5 speed and have injectors with part number 280155700 in it and have been getting a trouble code 27( injector not firing when told) not sure if these injectors are good as the problem is intermittent. I have replaced the TPS and repaired a lot of vacuum leaks to where I am good on that end but still have the problem and it is running very lean( ghost white plugs) I have read that these injectors can cause a lean run, so I was wandering if these are good to use or would the 280155703 ones be better?
All help is appreciated and welcome

I'm about clueless. Until someone else comes along, in your shoes I might check/clean any wiring connections. On the injectors, and even on the PCM. "control circuit" this says:
>27 Fuel injector control circuit. Will need specialist diagnostics.<
Btw, the days of "chocolate brown" plugs, ended with electronic fuel injection. Our plugs normally run pretty white. Good luck!
