My Centruy starts like a champ. The problem is that about 45-60
seconds after starting and idling fine the engine starts revving up
and down, higher and lower until the rpm’s drop too low and the engine
quits. I’m not getting any dummy lights. About 202k on the engine.
Also new air filter. After about 5 mins of driving it’s fine all
day...until the next moring and the cycle repeats.
Any suggestions for where I need to start looking?
