My engine light is fortune telling

As you may or may not know, I have been having problems with a random misfire caused by code 14, (possible serious problem,thread) was just wondering why the engine symbol light comes on a good 3 to 5 seconds before I can feel any misfire, I just thought it strange how the light comes on before the problem has started :blink:,,,,,,thanks ,,,,,,mark

It may be reading the start of some igniter feedback malfunction long before you actually feel it. In the digital electronics world

3 seconds can be an eternity. The issue is almost certainly in the ECU to igniter wiring or igniter to coil pack wiring, or the units themselves.

Swapping out the initer, coil packs and ecu in turn with known good ones would be a DIY possibility. Do you know anyone well enough

who would be mug enough, ooopps, sorry *KIND* enough to do that? ;)

Yesterday I unplugged the Ignitor connections and gave them a good dose of wd 40,since then I have driven up and down my local road for at least 4 hours with no issues , also ordered new coil packs and the terminal repair kit,,,,,,, I know this is not a great explanation but what is the ribbed hose that feeds into the top of the engine underneath the Y shaped pipe, because the ribbed casing has come away from its fixing point at engine side, is this the wireing from the ignitor module?,,,,,,,,,,,,,,,Very much appreciate your help Chris, will have to repay you with an order for your pads in the near future, do you do the pads for the ls400 upgrade???

I just checked it out it is definately the plastic covering for the Loom, just need to find out how it is supposed to be fastened on, looks like it was taped on before , I was only asking as I didn't know if it was crucial or not to have the loom covered, I would have thought it was because of heat etc, ...........as for the well done comment ,I am not counting my chickens yet, as I said before this problem comes and goes with sometimes days in between with no problems, I really wish that if the problem comes back (god forbid) it stays misfiring all the time then at least I can play about with it until it stops........ My pads are quite new(blueprint) I only done the upgrade a couple of months ago, heard so many good things about yours will definitely buy when needed , lexus front + jspec rear........Thanks
