2000 Discovery with 110000 miles. It came on about a month ago. I don't drive it daily. I ordered a brand new Bosch MAF and 4 O2's since they had not been replaced. I have installed the new parts, cleared the codes (1174, 1171) and the check engine light came back on after about 16 miles. I have kept up on the maintainance except for the plug wires have not been replaced. Like I said it is not my daily driver anymore, but I would like to get it fixed since the inspection ran out.

Any thoughts?

 

So, are you ready to now quit throwing money into some parts that mau or may not have been needed.
Call me and let see if we can brighten up your weekend.

Hey Mike, it looks like it was a throddle body gasket. I found the leak by spraying carb cleaner around the intake until it was pinpointed. I will replace the gasket tomorrow and see what happens! Thanks for the advise!

 

Let me know what happens.
