My car started having an issue with the idle. Before the idle would go thru the high / low then after a couple minutes it would settle on 900 and sit & run like a champ. Now it wont stop the high low. I noticed that at the low it acted like it was running out of fuel. I check the fuel system - pulled the pump, checked the hoses, pulled a couple injectors - all looks good. I put it back together and did a road test. It hesitates from a stop, but after it starts moving it run strong. I even got stopped by a police officer, lucky he was a car guy & just gave me a warning. Any one have an idea what I need to be looking at next ?
