Coil Packs!

[loz dog]

Ok, had a stutter and felt like the car was holding back around the 4500 rpm mark which after alot of reading seemed the coil packs where to blame and a test would be a good idea,

Tested the ones in my car and they all read 1.1 ohms, strange? Was looking for around 0.6 - 0.9, correct? I thought there might be a bit of difference in them so i tested ones out of another engine and again all where 1.1 ohms, even stranger? so i tested a load more and was getting the same reading for all of them!

Then warmed up my original ones and tested them again, this time they all read 1.3 ohms? So in therey, after all the reading these should all be f**ked, but surely this can not be the case?

Im using a multimeter set on 200 ohms, addmitidly the meter is a bit s**t, maybe this is the problem? Im testing them out of the car hot and cold and on the + and - pins, is there something else im forgetting to do, the way im doing it i belive im testing the primary coils and also how to you test the secondary coils?

Can anyone shed any light without the reply of get yourself some splitfires, thanks again..........

If u have an aftermarket ecu u can increase the dwell times. This will fire your coilpacks for longer and ensure a good spark. Increasing it also reduces its life.

You can also reduce the spark plug gap to 0.8mm to reduce misfire brought on by shite coilpacks
