1. I suspected the coding plug but was trying not to think of this. Will check.
2. Your statement matches my observations of the o-rings. The ones that hold injectors into the rail are flexible, while those in manifold are hard to squeeze and can't be reinstalled because they just break into pieces. Just last weekend I removed the fuel rail along with the injectors for a wash. At least one is clicking loudly. The wash device pump failed during first injector cleaning, so I had to buy a new pump. Will resume on the weekend. I'll replace all o-ring and will see if this kills the noise (and the wash restores the pattern, what is primary objective). It is M30B34 of 1991.


Regards,

Greg
