I have been having a random limp mode issue for the last 4 months car will go limp (no throttle) after driving it would happen maybe once or twice a month and last a few minutes then back regular no codes but recently a month ago i went limp mode again but vdc light comes on and dash lights flickerd and car died out i finally had a code come up for cam shaft crank shaft and a wheel speed sensor i replaced all cam shafts and crank (didnt replace wheel speed sensor) and replaced altenator (i noticed a burn on the back of altenator by the voltage regulator) i replaced my ignition fuse i replaced the voltage regulator wire connected to the alternator to battery because i noticed it was fried now after installing the car drives normal but after a few miles of drving its back to going into limp mode and dash lights flickering off and car dies any help? I know about the throttle position sensor throttle boddy and maf sensor i have done those aswell but that doesn’t explain why the dash lights flickering and car dying anybody ever went through the same issue?
