i have check wth my foreman, he say ignition coil if broken cannot check.....just replace all of them....anybody could help>??:retarded: :retarded: :retarded:
coz i need to 100 percent sure wats the main problem? will becoz the sensor?
anybody pls...
Firstly...the procedure for ignition coil check has been posted. Whilst I have not done it myself, I can vouch that, as an electronics professional, this IS the correct way to check discharge coils. The difference is only in the value of the resistance.
Next, when they say "broken", do they mean physically broken or just not firing properly? Cos the coil pack has a long neck leading down to the spark plugs, and I have broken one or two of them before removing them to replace my plugs. After a number of years, the plastic becomes brittle, and you have to remove them very carefully.
Finally you said "a light pick up". What does this mean? Did you have a dashboard warning light? And if you did, which light was it?
What your description implies is that you somehow triggered the knock sensor. A lot of vibration, and then you push harder and then lose all power implies that your car went into "limp" mode in order to protect the engine. What we must determine now is HOW you managed to trigger the knock sensor.
I have no idea if misfiring coil packs will trigger the knock sensor. I suppose it is possible if you miss repeatedly and the fuel somehow ignites at the wrong time causing mis-firing or back-firing. This is because I HAVE NEVER PUSHED MY CAR FURTHER IF I DETECT MISFIRING OR IF AN ENGINE WARNING LIGHT COMES ON!!!
It is a sure way to destroy your engine...
You have to check the coil packs again. If they are broken, then there's not a lot you can do. However, I do have one or two pieces of old packs with me that you might be able to scrounge the long neck off and reuse your original coil pack. If some are burnt out...and to my knowledge, I have never seen ALL 6 burn out together at the same time, then my spares may come in handy.
AND DO NOT PUSH YOUR ENGINE LIKE THAT AGAIN WHEN THERE IS SOMETHING WRONG!!!
