Stated my car up this morning, then after the car was on for about 3 minutes it bogged out and turned off. I could not get it on again after that. Then in the afternoon I checked intake, intercooler pipes. retightned everything then it fired up again and did the same thing. turned on for 3 min and turned itself off. rpms drop then car struggles to stay on till it dies. Any ideas? thank you much for the help!
