I've been chasing gremlins in my 1995 Big Bronco (EB). Finally getting proper results (its been a long hard grind chasing problems - step by step). It (check engine light is no longer) has stopped glaring at me constantly...Yeah, me! I was chasing sensor malfunctions until I was seeing vacuum lines in my sleep and EMC circuits were starting to invade my dreams. I'm much better now... the meds are helping too.

Current lingering issue is an intermittent miss, mostly at idle, after cold start but also randomly while sitting in traffic.

I am thinking about remove and replace injectors (124,200 miles on the still original engine) or remove, clean and reinstall the originals? I have this thing against buying rebuilt injectors - If I have to pull the intake top-half off, might as well just do the whole job.

does anyone have the color code which tells which injectors are in the engine now? the color is a yellow-ish, brown (not Tan, not quite yellow either). From what I read; they are supposed to be either 17lb, 19lb or 20lb? Either I'm reading them wrong or the texts are just confusing.
*sorry about the , long post... detail in the request cuts out a lot of guessing in the answers...

1. replace wires and distributor cap? ... factory wiring availability (grey and numbered -or settle for Blue FMS?)
clean or replace injectors? ... what flow rate?
replace PCV on rear, head to head connection pipe?

 

Your injectors are faded orange-top 19 lb. versions.

Highly suggest you replace the cap/rotor and wires with good quality pieces. Personally I like the pretty blue FMS wires. Be careful how you route them. Cross-fire is a very common problem on the 5.0L and 5.8L engines.

PCV, yes replace it since you have the upper intake off.

Head to head pipe, is yours leaking?
