This my daily run about - i've had the tdc sensor fail on me twice causing me to brake down,the first time it wasn't replaced with a genuine part, so once it failed again i obviously replaced with a genuine part and that seems fine?!.........i also have problems with the coil packs....
Recently, i've changed 1 coil pack twice in the space of about 3 months, and last night the car was running lumpy and seemingly just on 3 cyclinders - and hey presto - another coil pack has gone (not the same one just replaced!)
It's been recommended to me to replace them 'all' once 1 goes faulty?? and i've also had it mentioned that perhaps the spark plugs should be replaced for genuine parts??
I've tried various coil packs - all from GSF and varying prices (£12 to £25) and makes. The spark plugs have been either bosch or NGK, once again from GSF!
Driving home tonight the car is still 'stuttering' and not ticking over as smoothly as it should....................
I'm wondering could excessive corrosion in the exhaust cause a sensor to be not operating properly? (exhaust mentioned in the last MOT - December 2009)
Or could it also possible be the Catalitic Converter is needind replacing??
I know the history of this car, it was my dads previously and he owned it from new! and both exhaust and Cat are the original, so well over due replacing perhaps!
It's also just clocked 79'000 - Can any of you guys make any suggestions on things i can check??
From previous searches i've also read that the injectors can become 'clogged' so perhaps an additive to try and flush it through?
Pretty sure it's a K4J engine, but would need to confirm
Any help, advice is much appreciated
