RaidersR1, I'm willing to bet it's your Mass Air Flow sensor in the the engine air filter box. The MAF probably just needs to be cleaned. (Do you use an after-market high flow air filter, like K&N; if so, your MAF may be getting dirty). I think this is not related to whether or not you let it warm up for a while before driving off.

 

I have a Fabspeed CAI. I will pull it and clean it.

 

RaidersR1, I'm sure you already know: make sure you never touch the MAF wire; use a MAF spray from your auto parts store to spray off the contamination and let air dry.

 

Going to pick some up today after washing car. Thanks.

 

Your car idles @900 rpm?

Mine does @750 and this is what several members have posted.

Its always the right thing.
Letting it warm up only does one thing... it takes longer to warm up (since the engine isn't working but just idling) and it thus just wastes fuel and pollutes the nearby air needlessly.

Start it up and drive it off. Driving it will warm the engine faster than sitting there.

 

easy. it's a 3 step thing:
- start the engine
- open the cab roof
- drive it like a toyota camry until oil temp reach 200

you don't have a cab? then no clue how long you have to wait before driving it

 

i

Roll windows down open sunroof ? Same amount of time

 

Oh, the coupe just has a two step process...

1. Start engine
2. Take off

 

Turned out to be a dirty throttle body. Cleaned up and is fine now!

Didn't think that amount of dirt would get in there.

 

Glad you got it sorted...I guess that tells you how effective your CAI is in filtering out dirt.

 

Thanks for the follow up, and glad it was a simple fix!
