hello guys today out of the blue my car decided to play up. its a 306 xsi 2.0L.

i checked all the sensors resistance and they looked fine. i checked the injectors resistance it looked fine. check the compression of the cylinders all fine aswell.

i am strarting to think that the coil pack needs replacing i looked on ebay and theirs a few goin for not a bad price.

the question is will a coil pack form a 1.8 xsi be ok on a 2L or are they different?

also the resistance of the Lambda was 5 ohms but the data sheet states 20 ohms max. if less than 20ohms is it ok or not?
