Tachometer swan dives; 88 Volvo 740 Turbo

Aug 21, 2003 2 Replies

After I press in the clutch and let off the gas, as in when I approach a stop sign or shift, my tach will plummet to the first notch above zero (less than 500 rpms) and then climb back to 1000 and idle steadily. If this gets worse I will be stalling out, obviously. What is going on and what can I do to repair it?

Clean the throttle body and check the adjustment of the throttle plate.
