Getting 12.89 mpg!!!! Need help!! (Searched already)

[EagleTalonTim]

I have posted this already, but no one had any other ideas than the O2 sensor or the Coolant Temp Sensor. THOSE ARE NOT MY PROBLEM!!!! I have already done my research on this, but cannot find anything that works.

I am getting 12.89 mpg!!!!

My setup consists of :
93 Eagle Talon TSI Automatic AWD
Everything is Stock.
All boost leaks are fixed. Before one around the TB was fixed, i got 13.98 mpg???
No Vacuum leaks. (Will be doing the vacuum hose removal probably tomorrow)
Brand new direct OEM replacement O2 sensor from Oreilly Auto Parts.
Brand new Coolant Temp Sensor. (the one with 2 male connectors right next to the gauge sensor)
ICS replaced with a working one in perfect condition. (I tested it as the book states and from what I found on the site)
Timing is 5º advanced.
White top injectors (stock)
Brand New K&N filter with chopped can. I did not mess with the MAF.
Brand new exhaust 2 1/2" pipe, no CAT, Turbo Muffler, with dual out Tip
Getting exactly 10psi with the stock 13g TD04 turbo.
Brand new NGKBRP6E3 Spark Plugs and wires. Spark plugs gapped at .33
Brand new fuel filter.
Compression is 155 across all cylinders.
Timing marks line up perfectly. New belts and tensioners including the hydrolic one.
I adjusted the BISS screw while I set the timing to idle the car at 900 rpm.

How I tested my gas mileage:
I filled the tank and drove the car on the interstate at 70 mph not getting into boost at all for 60 miles one way, then I turned around and came back home. 29 miles later, I had to fill up again! I drove 149.7 miles and put in 11.61 gallons back into it.

I just bought this car a few months ago and it had 2 bent valves and was sitting for 2 years. I rebuilt the head and checked everything while it was apart. The head was fine.
I have put about 1,000 miles on the motor since I rebuilt it.

If I start the car, the car will idle at 600 and I can watch my boost gauge go from 0 to -10, then a few seconds later, it will go to -20 and idle fine. This happens every time I start the car. While it is at the -10 mark, black smoke is coming out of the exhaust.

I am stumped on what to do now. Please help me. Exxon and Shell are killing my wallet.

 

[northendtrooper]

your FPR could be messed up. what about your spark? check your spark plugs and see what they look like. come back to me

 

[xveganxcowboyx]

Possible leaky injectors. Black smoke is burning fuel and it could be pooling in the cylinders while the car is not running.

Here I am 10:30 at night pulling spark plugs in front of my apartment true DSM love there.

That is what I was thinking to about the leaking fuel injectors, but would it not be hard to start the car in the morning after letting it sit all night? My N/T had a leaking injector and it took forever to get it to crank.

I had my neighbor help crank the car over while i watched for spark. It was blue and hit every time. I left the wires down in the cylinders an #1 blew out a ball of fire on the first crank with no spark plug on the wire or in the cylinder. :0

Here is a pic of one of my plugs. Not the best quality....stupid camera.

Obviously this is a fuel problem. Maybe if you had something to tune or log, you could see whats going on. Any CELs?

 

[EagleTalonTim]

Unfortunately, I don't have any way to log the ECU Can't afford it right now. No, there is no CEL.

Your fpr pressure is not set correctly.
You have leaky injector.

White top injector are not stock, check and make sure they are 390cc for auto turbo and 450 cc for turbo manuals.

Your ecu is messed up, check for leaky caps.

Is there any way to check if the injectors really are leaking?

The FPR is the stock one.

What are the white top injectors? I was told they are stock for the Automatic turbo talons. How do I tell what kind they are?

The ECU was replaced 2 years ago right before the car jumped time and was parked for 2 years with no battery on it.

Where can I get an inexpensive AFPR that bolts up perfectly? Preferably under $100. I searched Ebay, but did not find anything I liked.

 

[Pro3racer]

Just slap on another stock working one, it could just be leaking(diaphram leaking). Those plugs are black, way to much fuel. Find another set of injectors, should be very cheap.

 

[EagleTalonTim]

a new one will cost $60. I am eventually going to upgrade the fuel pump so I don't want to buy a part I will be replacing anytime soon. I am not too sure about these AFPR's on Ebay because I bought one for my N/T and the gauge stopped working and the backing inside it started to peel.

As I posted earlier :

[xveganxcowboyx]

You should be able to buy a functional stock FPR for $5.

A logger and cable costs $30 if you buy carefully on ebay.

Just buy a set of used injectors. 390's go for nothing anyway.

 

[northendtrooper]

megan sells for 100 for the FPR.
got mine new for 50 from a friend

 

[EagleTalonTim]

Ok, new update.

The ECU in the car is an MD166255. I found that this is for an automatic N/T FWD. I do believe that is my problem. I need an MD193300. anyone know where I can get one cheap and fast? I am surprised that there are no codes though.

 

[spyderturbo007]

EDIT -> Nevermind my post, I'm an idiot and posted links to 2g ECU's.

Thanks for setting me straight bling5tatus.

 

[bling5tatus]

dsmtrader, or here if you search the classifieds. oh and one of those links you posted for an ecu was for a 97-99 ecu, he has a 92 talon...

You may also check ffwd

[EagleTalonTim]

ffwdconnection.com is expensive. I am just looking for something cheap. No Junk Yards around here have a turbo talon I need an ECU for a 93 turbo talon AWD automatic. Preferably around $100 or less. I found nothing the classifieds.

What other ECU's will work? What are the MD numbers?

 

[xveganxcowboyx]

Use one for a manual car and add 450cc injectors.

 

[EagleTalonTim]

will that work with the stock 13g turbo without tuning anything?

since no one has replied to my other replies, i have been searching and found nothing. I was wondering if since it is burning so rich and everything else checks out fine, could I just upgrade the turbo to a 16g and leave that computer in it? Should the engine even be running with no CEL even though the computer is for a 2.0 NT FWD??

And once again.....
What computers will work in my car without changing anything?
If I got a computer for a manual transmission turbo talon and injectors, would that work with the 13g turbo?
Since I was told in an earlier reply that the white top injectors are not stock... What are they? What size or cc?

 

[Wpgdsm]

Use one for a manual car and add 450cc injectors.

A freind of mine tried using a manual ECU with his auto and the car would only go into
reverse because the ECU controls the trany along with the motor. You will definitly need an ECU out of an auto car. My freind also had various problems with using ECU's out of different years.

 

[EagleTalonTim]

uh oh. i already bought a computer for a manual car I was told it would work as long as I upgraded the injectors. This is not good! Are you 100% sure that it will not work? Is there anything I can do to get the ECU to work correctly?

Dont post unless you know what your talking about , a manual ecu will work in an auto, i am running one. The transmission has its own computer called a tcu. it would be best if you use 450s if you get a manual ecu, or use someting to tune them, but it will definatly work.

 

[EagleTalonTim]

wheeew....had me scared there for a minute. When I get the computer, I will update this and tell if it works or not and if it fixes my problems.

 

[xveganxcowboyx]

Sorry I didn't notice your post after my last one. As was said above the ecu will work fine as long as you also change the injectors.

Also, the turbo doesn't matter. The 13g has less big power potential, but makes boost just the same as any other turbo. Different injectors or any of that won't matter as long as you're running near stock boost levels.

I'm just going by what we experienced when we did the engine and trany swap in my freind's 92. When we just did the motor he wanted to run his modded ecu and it would only go into reverse and when we switched it back it moved fine. After that he switched it out for a manual trany. Somthing in this combo didn't work so I thought I would pass along my story to another in hopes that this person would not run into the same problem.
Isn't that what we are here for, to share our experiences and knowledge with others who need it. It's not like I'm making this up I watched it happen so I thought I would share.
