Weird thing going on...need help
#1
Recently I've noticed a strange power loss after about an hour of city driving. Is this caused by warm air in the air box or what? My car stops pulling as hard as it usually does, the engine growl becomes deeper. So now I have to depress the gas pedal pretty hard to gain some speed. Anyone knows what I'm talking about? It seems like there is something restricting the engine. I dunno, it just bothers me. Any suggestions?
Thanks.
Thanks.

sounds like the cat
same thing happened to a van I had. If I eased off the gas it cruised fine but when I tried to pass or speed up it slowed down. Always started fine and idled good. Just the acceleration was like I was pulling a trailer. I had my wife rev the motor while I listened to the exhaust. It sounded like a lot of air being pushed out. Got a new cat and it felt like I just put on a turbo.

could be a leak somewhere in the exhaust.once I purposely unbolted the cat just a bit to leave a crack open and drove around for awhile. drove fine until after around 45mph it started to loose power. when I floored it, it caused the rmps to go way high but I was still around 35 mph.

Thanks for all your replies guys, I'm gonna get the exhaust checked as soon as possible.
This is very strange, i still can't understand why this happens only after I drive my car for some time. In the morning it pulls just as hard as it used to, but after being driven for about an hour there is this strange loss of power.

This ...
... and this ...
... both sound like clutch or transmission trouble, unrelated to the exhaust system.

Man, that's exactly what happens with me. I step on gas and the RPMs jump up to 6K, I still gain speed but very slow. ...

I'm sure it's not my tranny, i got it inspected not too long ago.
Just called the dealership, made an appointment for next thursday, we'll see what happens.

Well, see, the RPMs won't just rise if i step on gas as I usually do. In fact rpms stay low, 2K or lower. This is what confusing. Say I go 35mph and want to go faster. In the mornings when my car drives fine i give it a little more gas and the car pulls. The same situation BUT after being in heavy traffic, i give it more gas but the speed increase is much slower and the rpms won't even go high. I give it more gas, rpms go just a little higher and the car starts pulling but still not as hard, seems like something is holding it, like someone here said "it's not breathing right". If i floor it, the rpms go very high and then car starts to pull. But with all this I also noticed the difference in engine growl, it became much deeper.
The delaer said it might be an air flow sensor, so I'll have to wait till next thursday to find out what's wrong.

Yes my max is auto.
The mileage is fine, just as it used to be, and I replaced the air filter less than a month ago. Not sure about the throttle body, gotta check that.

It's not a filter, it's just a screen

I,m not sure if this holds true but I know for some transmissions if the filter gets dirty it won,t shift properly. I thought I read a post that states the filter/pickup screen does not normally get replaced but maybe (a long shot) it is somewhat dirty/clogged which would restrict fluid flow. This is basically a guess on my part. Perhaps Dan B. Max could shed some light.
