Hey guys im new to the form have always lurked here for very useful information but its time i make my own post
I have a 2002 p38 (bosch engine of course)
well a couple of weeks ago i decided to change my spark plugs due to the fact i was only getting 15mpg
i used ngk iridium plugs all went well for a couple of weeks gas mileage went up to 18.0
then all of sudden on way home service engine light comes on.
the codes were p0134 and p0154 p0455 i dont know if it had anything to do with spark plug change but its good to have backround info so i looked it up online and put a new gas cap on it p0455 went away but when i read my codes once again it gave me p0134 p0154 p1413
i revised the vacuum lines and saw that one was disconnected hopefully that solves the p01413
my question is would p1413 have any effect on the two other codes ?
