Default 1999 Honda Accord V6 problem, please help...?

I have a 1999 Honda Accord V6 and i have had some minor problems with it but now it is getting worse and worse, I can literally feel the drop in horsepower of the car basically every week, and most of the time its when i accelerate really fast. Do you think it could be the timing belt, or what. Thanks

I don't think it's the timing belt. Try air cleaner. run a couple of tanks of high octane fuel. See if it cleans it up.

There are several things that can be happening based on your description. Its hard to tell from your description if your problem is caused by an engine component, an exhaust component or a transmission that is slipping.if you see the rpm go up quickly on your tachometer but the car doesn't feel like its accelerating then you more likely than not have a transmission problem. That can be caused by everything from low transmission fluid to internal damage. So first thing is to check the transmission fluid. it should be pinkish and full. if its low or brown, have the fluid changed.second, if the car makes a roaring noise and feels like its not going anywhere and the rpm does not jump up when the car doesn't move, you may have a restricted catalytic converter or exhaust system. A mechanic can do an inexpensive vacuum test on the engine to determine if the exhaust is restricted.lastly, you didn't mention if the check engine light is on or not. if one of the engine sensors is malfunctioning it would throw off the fuel mixture and cause a power loss. Same if a vacuum leak exists in the recommendation would be to stop by a shop in your area and take a technician for a ride to demonstrate what the car is doing. Let them experience it and give you their opinion. if they feel testing and diagnosis is required its more cost effective to pay for that then make a decision when you know the cause as to whether or not to do the repairs. its less expensive than spending money on guesses.the timing belt won't cause this problem. the timing belt and spark plugs should be changed at 105,ooo miles.hope that helps
