100 degrees out + AC = INSANE throttle lag?!
I'm really disappointed with the throttle lag of this car.
I know the engine is considered to be pretty slow, but once the damn thing wakes up and says "ohh hes pressing the gas pedal" it feels like its got good power.
Problem is since it got so hot out and ESPECIALLY with the A/C on I can floor it and the damn thing just sits there slooowly revving up until finally it jumps and goes. No check engine light.
Any ideas on what I can do to try and diagnose this or is it normal? I expect if I take it to the dealer they're going to tell me its normal, in which case, I should have bought a KIA.

Yep, im in NYC. Yesterday it was the worst, I started it and went to pull a U-turn, had the pedal to the floor during a U-turn!! And the car was basically like "nah not gonna move any faster than this".

well, not necessarily... the throttle lag is there, I drove out to the city today, the cluster read 102F, I had the A/C on full blast and floored it down canal street, there was just a slight throttle lag, wasn't that bad. no offense, maybe its the 240!!!

well i had a similar problem before. i would be slammed on the gas and the car wouldn't move .. until about five whole long seconds passed. then it would slowly accelerate. i would turn car off and then back on and it would be fine.. turned out to be a faulty electronic throttle sensor?
or something to that effect.
BTW,
congrats on the new bimmer advans. that car is sick.
if you get it in white.. ima suggest getting bright silver HRE spoke style rims.. and no tint. I saw a 335 like that, and it was hott..

have you guys done the throttle reset? it works.
also, I've noticed the car's performance according to the amount of gas in the tank.
I've noticed that the car has the best response from full tank to 3/4 tank. then from 3/4 to 3/8 tank is rubbish. then less than that is best response. but...thats IMO.
also, try swapping out to brand new clean airfilters, it helps a bit.

I'm not too sure I buy the 'its a 240' excuse. Obviously its a slow engine, and obviously it was REALLY stupid of MB to go with a 170 hp engine in a heavy AWD car.
The reason I'm not so sure is because it's not that I don't have power, its the damn lag. Once the car 'realizes' that i want to go it gets up and goes. Not that I'm defending the pig of an engine. It's my one regret with the car.
We have a beater car, a 1993 Saturn with over 100k on it - 85 HP when it was NEW. And that thing has NO throttle lag WITH the a/c on in this weather.
