It start up but I kept my foot on gas?

MEMBER
2003 FORD TAURUS

I have Ford Taurus, it was parked for about 9 months (due to some title issue) without driving, now when I tried to start, first it start up then shut off after few seconds and after that it did not start, after few days again I tried, it was not starting and then next day I tried and it start up but I kept my foot on gas as soon as I try to release my foot from gas it shut off and again did not start and while engine was when my foot was on gas paddle, it was shaking. Before I parked 9 months ago, it was running great.

I will appreciate if you can let me know the solution.

Thanks

Hello,

It sounds like you might have an issue with the Idle air control valve. It could have gunk build up inside of it.
Many times if the IAC valve is dirty it can have an impact on the idle of the engine.
You can take the valve off and clean it. Usually that takes care of the issue.

Here are couple of helpful articles on how to clean the valve:

I have attached the diagrams for IAC valve.

It also can be a dirty mass air flow sensor. So while you are at it, go ahead and clean the mass air flow sensor as well.

Look below for mass air flow sensor diagrams.

Please let me know of any questions.

Thank you.
