I have an '89 Accord 4 cyl carburetor. For the past couple of weeks I have noticed that it hesitates after being shut off for a few minutes and then restarted. The hesitation occurs in the 1200 to 2400 RPM range but disappears when the throttle is opened up. It takes about 5 minutes for the hesitation to stop. Just in the last couple of days it has started to hesitate in the same RPM range at all times. When RPMs rise about 2400 the hesitation goes away. The hesitation is felt as very brief losses of power. Any suggestions? Thanks Jean
