Don't know too much about reseting comp.but I have seen a previous posting by Paul that disconnecting battery overnight forces comp. to relearn once reconnected.
I,m sure Martin's more in the know.
Cheers

ps.be sure to have your radio's security code on-hand!

Is the senser close to std location?They have to run hot to work.The reason they run shorty headers on 5Ltr's or put on first collector.
Yes reseting the eec can make a difference.Just disc for an hour or so.Keep radio code like said.

Yeah I was thinking O2 sensor too, most sensors you arnt supposed to use silastic to seal, even if its O2 sensor friendly.
