What are the symptoms of bad injectors?
I think my injectors are bad. When I tow my 5th wheel and go under load, it pulses, misses, chugs and generally behaves like I am letting off the throttle and stepping on it over an over. I am assuming this is the injectors since the truck is completely bullet proofed (FICM, EGR Cooler, ext oil cooler, banjo bolts, drain lone, HPOP, studs, name it it's been done.)
If it is my injectors, should I do OEM injectors or is there a good aftermarket replacement? Not really looking for power this is just a driver/tow rig. And...should I replace all eight? or just the bad ones?
