Hello,

I have a question for all the Turbo 2.3L four cylinder owners. I have a
1988 Turbo Coupe, and it has been very good to me. I have had no problems
since I bought it just this summer; no runability problems of anything.

I have one problem that concerns me. With the passing of the most recent
tank of gas, I estimated my milage to be 10-12 mpg. This sounds very bad
for a medium sized four-popper, even with the turbo figured in.

What have you been getting for milage? I know the five-speed is rated at
18-26mpg, and I have the automatic,which I would expect to have less
milage. But that much less?!?

If anone has encountered similar problems, how did you fix them?

thanx!

My mileage is typically 22 -26 MPG (averaged over 60,000+ miles). It is
easy to knock down to less than 15 MPG by keeping the manifold vacuum in
the pressurized (boost) range. You should check what your highway mileage
is during relaxed driving at constant speed. If this mileage is still
poor, you should have a look at your oxygen sensor and/or your EEC-IV
trouble codes.

(Disclaimer: these gas mileage figures are obtained with a 88 2300 turbo
installed in a Pinto; possibly less aerodynamic; certainly 1000 lbs
lighter! You mileage may vary!)

Please clarify what you meant in this message. I don't know what you mean by
pressurized manifold vacuum. How do I get it out of pressurized vacuum?
And how do I check the codes?
thanx,

Hello,

XR4Ti's typically get about 21-25 mpg depending on conditions/style
etc. If the EEC IV does not offer any direct hints have someone (or do
it yourself) check out the fuel pressure. It should be around 35 psi at
idle. One of the folks on the 'merkurlist' had a broken fuel pressure
regulator and he had a full 100 psi on his injectors while idling. Not
good. Fortunately it is not expensive to repair (his was $100,
including labor). Get the EEC IV doc from rahul.net that Scott Griffith
put together (can some kind soul please post specifics, I forgot). It
describes how to obtain the codes and what they mean. If you really
want to know how your car is put together I would recommend getting a
shopmanual from Helm (800-782-4356).

good luck,

Sander
