Technical power loss!

Technical power loss!

Does seem pretty slim, I would look else where probably.

a 0.2 ohm resistance difference is very small, and could be acounted for by poor multimeter accuaracy, probes, dirty contacts.

Got another good sei you can test with your equipment??

If T14086 is right, and he does seem to know his stuff, this is not much use anyway.

It seems very suspicious that a day after a cambelt change that you get an EM error. Does the cambelt change work in the same areas as the coils. (i'm not sure where bout the cambelt is lol)

yer but with 0.2 of a difference in the range, been 0.2 and 0.3 out of range is a big difference!

but if both packs are going why am i only loosing one or 2 cylinders? you think only the rear pack with 0.9 is the one failing?
 
as for the cambelt its opposite ends of the engine to the coil packs and as far as i know the only way they interconnected is the sensor on the cambelt (cant remember which is down there)
 
Thats kinda my point, its such a small value, your equipment may not be that accurate. If ya lived near me you could test it on mine. Got another multimeter, probes etc? I think your looking int the wrong area though and think it has to do with the camblet change.

EM probs may take a while to show up. I filled with redex earlier....35 miles later and i had spluttering/chugging.....used the correct amount etc, but it took that long before it afected the engine at all.

well it seems to be getting worse every day! :( was just driving up the dual carriageway and overtaking and it jst lost power! BMW flying up behind me and theres me with my clutch down revving the balls off it trying to get it running!

the thing im confused about is if its a electrical fault, why does revving high revive it?
 
Just checcked my coils which are running my car fine. These readings are on warm coils.

probe-probe resistance = 0.2Ω , this has already accounted for in the readings.


Rear coil 9KΩ and 0.7Ω

Front coil 8.93KΩ and 0.8Ω


I will measure again later when they are cold. I can't see there will be much difference though.

FRONT
0.8 ohm 0.8Ω
7.39 Kohm 8.93KΩ

REAR
0.9 ohm 0.7Ω
7.34 Kohm 9KΩ

yours are on the left, mine on the right.

Yours appear out of the reccommended range, but so are mine by quite a bit and im having no problems at all. If you look at my secondary it's 1K out!

/EDIT Does your meter read 0 ohm when the probe are connected? Or is there already a low resistance there?

im thinking along the lines of replacing both but as i dont get paid until a week on friday this is looking difficult!

can anyone else think of anything else i could check? which sensors controls the frequency at which the packs fire?
 
I'd suggest checking the TDC sensor wire. Make sure it's pluged in correctly and make sure it's not crushed anywhere. It runs up over the cambelt cover along with the oil sensor (?).

Played with my engine and put the air box back on. Trapped the wire under it and crushed it. Crushing damages it and it's no longer able to transmit the voltage / resistance correctly and the engine thinks it's reving slower than it is.

-> no power. About £25 from fiat iirc.
