Hey it’s my first time posting on this site but I have been looking at it a lot. I have a desert race this weekend and the 3.0L doesn't want to run right. It will run at WOT, idle (except when coming off of WOT), but it wants to die after you are running it a about 4,000 rpm and you let off and punch it again. It basically cuts out and stubbles on its face really hard and then it will pick up if it doesn't die and blows out black smoke. I have replaced the 02 sensor, MAF sensor and adjusted the TPS. Any help would be appreciated because I don't have any time left tell I leave to the race.
