I was getting the code 601 with the check engine light on my ABS light has been on forever. Bought a new PCM and put it in the Vin number and mileage was not programmed into it and it worked for about a month and now I have the same problem but the car the truck is not going anywhere. The higher the RPM the crappier it was running now it's just not really running it sounds like it's running on three cylinders or five cylinders. Its a V6. What do I do?

Do you
have the same problem?

IF U INSTALL A PCM AND IT WORKED FINE.I WOULD TEST THE FUEL PRESSURE FIRST. THEN MAY NEED A NEW PCM.
