I am going crazy on this one! I still have a miss under low speed, high load acceleration!!!
I have replaced the coil pack (#2 went bad), replaced the plugs with Autolite Double Plats (gap was out to .062), and replaced the plug wires with Motorcrafts (#2 wire went bad). The old plugs were very white when I took them out. I cleaned the MAF sensor wire with Berryman's. I replaced every vacuum hose and tube that even appeared to be marginal. I double checked the PCV, and retightened the UIM to LIM. The only thing I havent done is replace the UIM to LIM gaskets.
I can't get rid of the off idle, full throttle miss. I also get an intermittent miss or buck when accelerating in OD at about 1800 to 2000 RPM at 1/2 to 3/4 throttle. I'm at my wits end! What should I do next? A car crusher comes to mind...
