Background:
I rarely drive this car as I work from home, it's driven about 200 miles per month for the past 2 years.

Problem:
The car is very slow to accelerate and almost seems like it gets stuck in 3rd gear. It barely gets to 60mph.

Weirdness:
If I am in neutral, park, drive, reverse and brake pressed I can press the gas down (at the same time) and the RPMs do not change. Gas floored and nothing but an idle. If I let up on the brake about a second later the car's rpms go up accordingly.
Do you
have the same problem?
Yes

Do you have a check engine light?

Check and test the MAF, TPS and VSS sensors

I can't remember but I think the check engine light was one a few months ago. Maybe it burned out. Hmmm

How would I check these sensors?

You need to bring it in, if you're not electrically incline and capable of using a DVOM-Try getting the computer scanned maybe it might pop up with something to start. What I gave could be some of the causes and could be tough to fix-

Hesitation/Stumbling/lack of power:
Oxygen sensor
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

The automotive place I took it said I needed a new ECU and it would $1600. I thought that was odd or a little unreasonable to jump into. I spoke to a friend of a friend that works at a tech school locally. He said to try heet and maybe a fuel injector cleaner. He said that would be the easiest, cheapest possible fix.

That was yesterday, I noticed the odd braking weirdness today. I added heet today and a fuel injector additive. Am I approaching this wrong?

Thanks for your help.
