WHAT DO YOU THINK IS THE PROBLEM WITH MY CAR? HELP!!!

2006 Honda Accord • 80,400 miles

I am experiencing a number of performance issues with my Accord. I had noticed these happening off and on about 8 weeks ago, but now they are constant from the time I first start my car and drive it to work in the morning, and then start it up and drive it back home everyday! It's very frustrating because I had experienced these issues with a 2005 Nissan Frontier pickup late last year and I ended up trading it in for a 2006 Honda Accord. Here is what I am experiencing.

When I'm driving in general, the car seems to hesitate a lot upon acceleration. I have to really press on the gas pedal to get the car to speed up. When it does, I notice that the RPM is at 2000 and it doesn't gain torque. I also notice the speed increasing at a slow rate, but it does speed up. The best way I can describe what I am feeling is the car is trying to struggle through a pool of thick molases. Very restricting.

As I accelerate for a couple minutes to gain speed and then let go of the gas pedal, I notice the RPM drop rapidly to about 1000RPM and then slowly raise up to 1500-1600 RPM. I really feel a hesitation when trying to accelerate any higher than 2000RPM. I can feel the speed increasing very slowly, but I don't feel the downshifting kick that you would usually feel when trying to go faster.

Also when the car coasts, it feels like it starts to slow down very rapidly on its own. You can feel the car slow down without even stepping on the break pedal.I can feel myself kinda lean forward as if I am stepping on the break. The break pedal feels kinda heavier than usual too.

At the same time all this is happening, I notice the steering wheel becoming harder to stear, the gas pedal suddenly needs more force to press down, and the suspension ride feels as if I have a cow or something on top my car and is putting a bunch of weight on the vehicle.

Here's the tricky part of all this.I have no CEL whatsoever. I don't know if this means that I don't have any error codes though. Would the CEL come on 100% of the time if there is an issue? Transmission fluid is new and there are no leaks or burning from the transmission. Spark plugs are new, air filter is new, but I don’t know about the fuel filter. The car has 80,000 miles on it, so I doubt it ever got changed before….

I have experienced this with a Nissan Frontier as well and couldn't get it looked at before I traded it in for this Honda, so I never knew what caused all this. I am hoping that someone can help me with this. The Honda dealership techs continue to tell me that there is nothing wrong with the feel, and I know there is. Please help!

Just because the CEL is not showing in my dash, I scan can still throw codes?

If any trouble codes ahd been triggerre, it would be recorded in the ECM and you can retrrieve the trouble codes, unless you have disconnected the battery or used a scan tool to erase.

One last question, are sensors the only things that would cause the check engine light to come on? I was told my an independent mechanic that a scan won't show anything unless the CEL shows up. So, what you're saying is that there may be codes stored and I wouldn't even know it if I didn't get a scan performed. Am I understanding you correctly?

Yes, when an error occurs, trouble codes would be stored and if no problem had been detected for more than 40 start stop cycle, the ECM would self erase the codes, otherwise it would be there.

Sensors, ECM, bad ground circuit connections, main relays are possible causes of the MIL to indicate.

Can a fuel filter clog cause everything I mentioned earlier too?

Yes, a clogged filter would reduce the fuel pressure and during sudden acceleration, the engine would tend to bog down.
