After I start my car in the morning (only the first start up of the day), it will shudder and not kick up the RPM's right away. I'm used to starting it and have it kick up to 2000 RPM. It will only shudder for a second or two, then it kicks up the RPM's and will run just fine. I have no other running problems. I don't use the car as a daily driver. And it occurs if I drive the car every day (beater is in the shop), or once a week. Any help will be greatly appreciated!

 

How old is your battery? Check the charge on your battery.

 

It's the original battery from '01. I'll check that.

 

Battery and charging system tested good. Could this be a bad MAP sensor?

 

I have that same exact problem. just started. two days ago. Tech I work with suggested I clean my throtle body. So I'll do that tonight and see what that does.

 

SUCCESS!! cleaned my throttle body and it starts fine now.

 

backspin23, can i ask how you cleaned your throttle body?

im thinking of cleaning mine and would like to know how you did it.

might not be the right forum to ask this...so i apologise for that.

thanks

 

Since you have Drive by Wire, I would NOT recommend cleaning your throttle body. You may mess up the throttle or the ECU. I've seen this happen on quite a few DBW.

BTW - I replaced my battery just to see if it would help the problem, and I haven't had the starting problem since.
