My car seems to idle ok, but sometimes...the Tach, falls to zero RPM's?
My car seems to idle ok, but sometimes...the Tach, falls to zero RPM's, but the engine is still running. If i race the engine, the Tach jumps back up with the motor, but then falls back to zero, in an idle. I thought maybe I had a weak coil pack. I changed it with a screaming demon, new plugs and wires. That seemed to fix it for a couple of months, but now its doing it again ? i have also changed the clutch. The original had 156,000 miles on it. I thought it might be dragging, but the new clutch didn't help. It might be my imagination, but the car seems to have loss, some low end TQ. I have to really slip the clutch, to get her to pull off, especially on a hill
I would appreciate any help you guys can offer.
