4.2l codes question
Hi,
Three days after buying a 02 F150 e/w a 4.2l and auto combination the "Service Engine Soon" light came on. I stopped by AZ and had them drop the codes for me yesterday and they found P1157, p1131, p0171 & p0174. After checking in this forum I learned that the indications were of a lean condition and probably meant an air intake or vacuum problem.
This morning I starting looking around and found the filter cocked in the housing. Hoping the problem might be this simple I straightened the filter and disconnected the battery for about 20 minutes. When I started the truck up the "Service Engine Soon" light was out. I then drove the truck about 150 miles and the light did not come back on.
My question is, have I fixed the problem or just masked it. My assumption is if the problem still exists the light would come back on. Is this correct?
Thanks,
