Finally got my axle situation straitened out, but I'm having a few problems with the way the car runs. Problem #1 When I start the car when it is still warm the rpm's go up to 2000 for about 4 seconds then suddenly drop to about 800 surge back up to 1700 or so then drops back down and idles perfect. ???? Wondering if anyone has seen a similar problem or has and idea what to check. Problem #2 Sometimes when I pull away from a stop if I put the gas pedal down about half way the car feels like it is going to stall it bogs right out. Pretty much all the time while driving the car feels pretty sluggish in low rpm's, possibly due to the gutted cat.???? I am not sure maybe it runs proper but my old dohc zc seemed to have more torque then this motor. Any suggestions would be greatly appreciated.
