spring wasnt broke its all been redone, switched ecu took care of most of the issue now my 02 isnt reading very well, but i also had a bad thermostat in there so it wasnt going closed loop, thats being fixed the tranny shift points being adjusted and a bunch of new grounds. does the o2 have a ground? also hydrocarbons are very high and I have a fairly new cat?
