Archived Loss of power and severe drop in fuel mileage

[hoogkar]

I am experiencing a loss of power and my fuel mileage has dropped drasticall. Just came back from the dealer and he said he is ordering a fuel pump - does this make sense?



I normally run about 20. 5 mpg om the highway at about 70 mph and for the last two weeks it has been down to about 12. 3 at same speed and conditions.



I have good boost (22 psi) and fuel pressure has been running about 8 at idle and will drop to 4 at WOT. .



with the price of fuel this is killing me -- any ideas?



I read about an IAT causing poor mileage - where is this located?

Sorry , I was reading all the threads and posted this in the wrong forum - It has been reposted in the third generation motor and transmission forum.



Again sorry for using the 911 forum!!!!

It sounds like a leaky injector I would try a double dose of fuel treatment and keep a eye on your oil
