Hi all,
3.0 Audi V6. 128000 miles. CEL. Changed coil, swapped plug and injector. No change. Still #3. Has slight lifter noise on start up and runs a little rough on start up. Takes a few days to a week to set code P0300 & P0303. Daily check of readiness and pending codes show nothing. O2 sensors and MAF check OK. It's also using some coolant but no oily coolant or foamy oil.
Any ideas?

A classic worry with head gasket leaks is the potential for bent valve stems, too. *NM* Laz - Thursday, 9 June, 2011, at 4:41:26 pm |

If the plug is no cleaner than the rest then the likelihood there's a head gasket leak... MarcW - Friday, 10 June, 2011, at 1:41:20 pm |

Could also be the coil or injector wires Boxsterra - Friday, 10 June, 2011, at 11:51:24 am |
Now that ignition systems are distributorless, the next step is wireless! *NM* Laz - Friday, 10 June, 2011, at 1:31:41 pm |
The next step is not to get rid of the wires Boxsterra - Friday, 10 June, 2011, at 11:18:24 pm |
