Engine Problem, Please Help! - Problem Solved Options

Hi Guys,

I have a problem when I have just started the engine specially when the car was not used for an hour or so. And the problem is sure to happen on cold start.

Everything seems normal when I start the engine. But when it starts running, it seems like there is not enough fuel being supplied or maybe the throttle is a little sticky. The reason why I say this is because when I press the gas pedal as I do normally, I experience some hesitations. And when I press the gas pedal a little more the car will suddenly run fast and throw my passengers aback.

What I need to do is to rev the engine to about 3K or so whenever it hesitates. After doing this for maybe 3 to 5 times, the engine will start to work as expected. The longer I drive, the smoother it gets.

What could be wrong? Could it be the following?

• Injectors
• Spark plugs
• PCV valve
• Fuel filter
• Fuel pump
• Sticky throttle

What confuses me is: Why does it only happen at the start? I was thinking that it should always be the same if the problem is any of the above.

Please help!

Thanks

Auto or manual??

Clean your throttle body, use injector cleaner, change the fuel filter, and check your cap and rotors.
