Turbo D16 MISFIRING BAD, Need Help!!
The intercooler came in yesterday, I had not driven the car for a week or so. Between that time i had installed the B&M adjustable fuel pressure regulator and MSD Ignition 6btm. Put the intercooler in, drove it around.. it was fine on the way home. But later that night, when I had been driving it a while, it started sputtering and slowing down and stuff. The CEL light was blinking. Earlier in the day it threw 45, which is the map sensor. Reset the ECU and that was gone. As I was going up a hill, it started doing it, and i had to downshift into 1st and it wouldnt go anywhere, it stalled. It started hard and barely idled but I got it up the hill.
Today it did it again, and it was throwing codes 71 72 73 which is misfiring on cyl 1 2 and 3. Cyl 4 is running perfect. Cyl 1 is running lean. We checked the wiring under the cap and it was fine. Took the MSD ignition off and it kept doing it. It ******* sounds like a V8. Didnt mess with the timing at all, and the fuel pressure regulator is set to normal. No leaks or anything.
I also installed a walbro 255lph high pressure fuel pump but this seems to be working fine.
Let me know if you have ANY idea how to fix this misfiring problem, because it is misfiring BAD.
