Injector readings from ECU test
I folks I need a little advice please.

I have recently had cause to plug the Ol'Girl in to my local Indys diagnostics machine and was shown that at idle my injectors are throwing out values of +5/-5... Is this ok as I thought they were meant to be more like +3/-3 at idle?! Or is this a function of the remap?

Coincidentally the vehicle is really quite sluggish of late, especially low down in the rev range. Possibly Connected?!

She has covered 167k miles on these injectors, so they are no spring chickens.

Plus once or twice recently she has been quite lumpy on startup with much exhaust smoke, but fab when warm.

What are your thoughts folks?

Many thanks.

Have recently been through injector woes.....


Mine is at 147000, and one of the injectors was starting to perform poorly, so took the plunge and replaced all 5.

Idle values sit now (no map or anything) stable at +/-2 and occasional 3.

They should be lower than +/- 5 check for oil in the injector harness
