yer it is comeing up with falt coad 14,i dont no anyone with a 1jzgte ecu i can try tho?might take the ecu to a auto sparkey,

its not the timeing that was fine,i will cheek the coil paks for spark,but it starts on 6 then drops doen to 3 or 2 cylinders.so i no at the start they defently have spark,

anyone have a ecu i could try?im in chch.

How old are the spark plugs?

Have the injectors been cleaned?

Have you pulled the plugs and looked at them and into the cylinders for any signs of whether the misfiring cylinders are getting fuel but no spark, or vice versa?

Have you unplugged each individual coil one at a time while the engine is running to isolate which cylinders are causing the problem?

Have you swapped known good coils around with those on the faulty cylinders and then repeated the above step to check whether the coils are at fault or not?

Have you double checked all the wiring to make sure there are no shorts, earths, or other dodgy things in it?

There are literally a million things that could be causing it, you need to start doing some proper hands on diagnosing to eliminate the possibilities. Otherwise just take it into a workshop and pay them to do it.

i have cheeked everything i can,all the wireing is fine spark plugs are new and i tryed the old ones too,the cylinders are all ways changein what ones are missing every time i start it,at first it was only running on 2 and 5,then the next time it was running on 2 3 and 5,ill take the ecu to a auto sparky to rule that out monday.

all cylinders are getting fuel,i have tryed different injectors too,

i dont have any spare coils to swap over,
