Okay here is my problem:
Car on last refill (12/3) is getting 15.86 mpg! 189.8 miles on 11.966 Gallons of gas.
I have removed the TB and Cleaned the EGR passage ways.
That turned off the check engine light!
Was going to get new plug wires, but found they were replaced with 8mm Autolite Pro Series
Did not change plugs, I'm assuming they are good if the wires were changed, most of the time new plugs go with!
I do not believe its the Cat because the car does not run like a dumb truck.
It is not my conical intake because I had 16 mpg on second last fill up with it on. The last one was with the stock intake running to make my dad shut up about my airfilter killing gas mileage.
It is not my driving. The last tank of gas I only put the petal down at an intersection twice. And I have been turning off overdrive on all the hills in my area. This was also my dad's saying that I drive like a "speed racer" as he put it.
So now I'm down to that
A) The UIM where I couldn't clean from the bend to the EGR is still clogged even thought my CEL turned off.
B) The Car needs to be tuned like there is no tomorrow.
C) One of the 4 O2 sensors is crapping out, and the CEL is to lazy to come on. Also I would like to know how you can check if they are working right.
D) My car wants me to remove the badge so it can't live up to its name! lol JK Had to find some kind of humor.
My whole problem is that if I got 20mpg I could get away with not filling my tank one less time a month and could save $25 dollars I don't have with my part time job. And then put that $25 towards the car! :-)
Everything else is stock on the car except the air intake, unless you want to count seat covers, steering wheel cover, and the new wiper blades I put on....oh and floor mats.
It is a 1998 Duratec Auto. So if anyone has suggests or comments let me know! Thanks for any help I can get.
