When I bought it I went thru the list of items that are more open to fail. I changed the oil, Flushed the transmission, Radiator Flush, PCV Valve, Spark Plugs etc. Last week I did the intake top and bottom gasket to eliminate the P0171 & p0174 and it was a total success. Everything else is fine but the antifreeze is dirty again. I am going to take the reservoir out and wash it and then do the flush. The less dirt the best. I will keep my eye on the antifreeze after that.
