Try cataclean as suggested, also better quality fuels may help. It seems the precats are a bit rubbish on the 3.2s
OK thanks, but now I have some quick questions:
How does cataclean work? (i.e. how do you use it?)
Will cataclean's effects last for any length of time?
Can I "de-cat" the preCAT from the car?
Is there a way of switching off the EML light for that error, but still have it work in case of other errors?
How do people who have de-cat straight through exhausts deal with the EML light issue?
What if I wanted to replace the faulty cat, any idea on the best route? new? refurb?
What sort of price?
Is my logic of wanting the EML light to be off, but still work to tell about problems unreasonable? I don't feel safe just "ignoring it", because I may be ignoring other issues.
