Answer
HI STEVE,,GLAD YOUR TRANS IS BACK IN ACTION..DID THIS HAPPEN AFTER REPAIRING THE TRANS ?? I WOULD SAY THE WAY YOU ARE EXPLAINING THIS IT SOUNDS LIKE A PARTIALLY PLUGGED EXHAUST CONVERTOR. YOU SAY THAT IF YOU THROTTLE SLOWY IT DOES OK. CAN YOU REACH FULL POWER BY PUSHING SLOWLY ON THE THROTTLE OR NOT REALLY,STILL FEELS A LITTLE LACK OF POWER ??? IF SO, I WANT YOU TO REMOVE BOTH FRONT OXYGEN SENSORS [BEFORE THE CONVERTORS] AND DRIVE IT LIKE THIS TO SEE IF FULL POWER IS BACK..IF SO,TIME FOR NEW CATS. ALSO CK THE MAS AIR FLOW SENSOR MAKE SURE IT IS HOOKED UP AND CK AIR FILTER AND FUEL FILTER.. MAKE SURE FILTERS ARE NOT PLUGGED,THIS WILL ALSO CAUSE LACK OF POWER. IF NO CHANGE, MAY HAVE TIMING ISSUES..TRY TO ADVANCE THE DIST A TOUCH..I WOULD LIKE TO REALLY KNOW WHEN THIS STARTED SO I COULD ZERO IN ON THIS,BUT TRY THE ABOVE THINGS AND LET ME KNOW HOW YOU MAKE OUT..GOOD LUCK TOM..
