my car runs fine and will accelerate fine under light throttle, but under full-throttle it only makes it to about 4k rpms and then starts popping and blows black smoke out of the exhaust. If i stay on the throttle, the rpm's will continue to go up, but a lot slower and the car just is not fast at all now, dont know what to check. help out with any info. thanks
