hAY GUYS IT MY AGAIN. EARLYIER TODAY I WAS WONDERING ABOUT WHAT CAUSE'S MY 97 GMC 3/4 4WD TO HUFF OUT GRAYISH WHITE SMOKE,IDLE ROUGH AND CONTINE TO PUFF OUT SMOKE AND ACT LIKE ITS MISSING UNTILL I GET UP TO ABOUT 1900 RPM. THEN IT GO'S AWAY AND RUNS GOOD! WHATS UP WITH THAT? I HAVE BEEN FIXIN THINGS ALONG TIME AND WHEN THEY SMOKE AT LOW RPM THEY USUALLY SOMKE WORST THE FASTER YOU GO. DON'T THEY? I HAVE BEEN READING THE POST'S ON THIS WEB AND THERE SEEMS TO BE ALOT OF PORBLEMS WITH PMD'S BUT I HAVEN'T HAD THE STALLING OR DIEING WHY RUNNING. COULD THIS STILL BE A PMD? MY INTIAL CODES READ CYL. BALANCE #2 AND #6 REPLACED INJECTORS (what a pain, I wish it was # 1 and #3) O.K. I'AM DONE WHININ' IF ANYONE HAS ANY IDEA OTHER THEN $499.95 I WOULD SURE LIKE TO HEAR THEM.
