Check measure adjust doc
 

Hello does anybody have a clear image of page 5. This is the page that has the block diagram for all the functions of the later MFI system. The online version is too fuzzy to read and once blown up loses all readability.

I am still struggling with an issue on my 2.4T motor. Cold the car runs awesome but as it warms it deteriorates, losing power eventually bucking and popping and then stalling out completely. This tracks and behaves the same each time according to my temp readings.
Up to 180 degrees runs great
180-200 runs poor and starts missing popping and backfiring
210 the car will not idle and dies.

All the cold enrichment components are in place and working and the pump had be recently serviced. It seems the car is leaning out as it gets warm? I tried to richen it 3 clicks but it seemed to have little effect. I plan to put a fuel pressure guage in to see if I'm getting fuel starvation. Should I try to richen the pump some more? any ideas would be appreciated.

thanks, Joe

Ok, I found a better version of the document. Nothing there that helps. The thermostat is out of the picture long before my problems begin. Is there anything that controls the fuel ratio mixture with the temp of the motor after the thermostat kicks out?

Joe, you are going to have to get some tail pipe readings. Either CO or o2 to see what is happening. Maybe your thermostat is stuck and needs some attention. you can pull the thermostat, heat it up and measure before and after to verify it is working.
