Thread: Help! Car won't start without pressing gas

Hello everyone, my 04' Grand Prix has trouble starting sometimes. Usually I have to press the gas in order to get the engine to start. After that it runs like a champ! But if the car is sitting over night it starts normal (without pressing gas) But it's very annoying and I know it's not supposed to do that. I'd like to know some of the possible reasons it may be doing that. I also have a engine light on for a bad thermostat and was told it may be related but I'm not sure how. Any help with understanding my starting problem would be great help, Thank you.

Okay thanks how should I clean my/what should I use to clean the MAF and throttle body?

Okay thank you, I just want my car to start normal again

For the throttle body, should I just clean the boar or should I clean whatever is in the electronic control modual attached to it?

Don't be afraid if a little coolant comes out, it won't be much if any, but there is a coolant passage that goes through the throttle body. Check the gasket while you have it off.
