What performance results would fixing these symptoms give for my car?

So my car is an 2003 Honda Element 4 speed auto awd. Sometimes when I take off the line my truck accelerates quicker than it does at other times meaning sometimes when I takeoff from a light stop, it gets up to high speeds quicker at lower rpms than usually but that is usually after I've driven the car long enough to really warm up. Also it gets up to higher speeds more easily. Initially, after a few min of warm up, it takes a bit of effort to get it accelerating off the line.
My car has 140,000 miles btw. Use 6-20w synthetic oil by royal purple

Anyways, I recently had a Diagnostic test done on my car due to a check engine light and they said I need the following:

-a new upstream o2 sensor
- fuel induction service done(never been done on my car)
-new set of NGK iridium spark plugs(OEM)
- and I might need a new engine air filter as well(not part of the diagnostic but it has never been checked in a long time).

Based on these symptoms, if I resolve all these problems, what performance gains will I get in terms of acceleration? Will it be slightly and noticeably more quicker and responsive?

Will resolving these symptoms on my car help it able able to easily go over 100 mph?

My car is a 2003 honda element and recently i brought it to the mechanic to find the cause of my check engine light as well as possible causes of slow acceleration(AT HIGHER SPEEDS) and bad gas mileage.
i'm aware that my car is no performance car so 0-60 and 1/4 mile times are not a concern for me, however a nonaerodynamic car with 160 hp should be able should be able to at least do a top speed of 110-115 mph maximum before drag limit prevents it from going any faster. So the fact that its a brick should not be an excuse. Also only being 140,000 miles, i've had other cars with as high as 160,000 miles that could easily go way over 100 mph.

from the results i got, it says the i have to:

replace my 02 sensors
-get a fuel inductive service done(which i've never done)
-after wards get a new set of spark plugs specifically NGK iridium spark plugs
-and the engine air filter needs to be replaced.

will fixing these things possibly help my truck go faster(about 110 mph). My tires are rated for 115 mph.

Added (1). i run 5w-20 synthetic oil if that matters. Transmission fluid is good.

Why won't my car go past 100 mph?

My car is a 2003 Honda Element and recently I brought it to a mechanic shop to do a diagnostics in regards to why I have a significant drop in my gas mileage and the check engine light. Anyhow, long story short, he took a good hour and a half and it turns out to be that my car has a faulty o2 sensor, and most importantly they recommended that I get a fuel inductive system done and after that process a fresh set of spark plugs and an air filter.

From the diagnostic results the only benefit I can see from doing this is perhaps better gas mileage. Will this have any affect on my cars performance, if any, at all?
My car has 140,000 miles on it. Sometimes when am on an open stretch on the highway, it can sustain speeds of 75-85 mph. However when I press on the gas to hit full speed, it has no problem getting up to speed until 90-100 mph(depending on the direction I'm traveling)At that speed, I'm only at 3750-4000 rpms and my car has a redline at 6500 rpms. Whenever it does approach 100 mph, there car keeps climbing up the rpm tachometer but the speed doesn't let me go beyond 100. I just feel like the Engine has potential to reach at least 110-115 mph before drag really starts to take a toll on it.

Would resolving these suggested diagnosis help my car have a little more power to reach my top speed?

Will this improve my cars performance?

So my car is a 2003 Honda Element 4 speedauto awd. Son two nights ago I was driving on a highway late at night around 1am in the morning and as there were hardly any cars around me, I was able to cruise at a good 85 mph. I had a long stretch of a highway in front of me so cruising at that speed, I decided to get on the gas to see what my Honda can top out at.
In attempt of doing so, at 85 mph it didn't seem to really struggle at that speed but when I gave it gas it was able to reach 90-95 mph. So finally I put the gas to the floor and I was only able to get it to 100 mph, it would no go past that speedometer but the. Again I only had a 1/2 mile of road space left in front of me. The engine was still happily up to redline(close to it) but the car would not speed up any faster. So the next day, I took my car to get a diagnostic check for performance issues that I might be having, there are three things that are wrong with my car.

They said I have to replace my o2 sensors, need new fresh spark plugs and most importantly I need an cleaning service called a '3 part fuel induction service' done on my car.
Will resolving these symptoms make a difference in my cars overall performance(being able to easily achieve top speed of 110)And my car only has 140,000 miles which isn't much to brag about cuz I see videos of ppl with there mileage over 200k and there car still can hit top speed.

What results will I notice once i replace the o2 sensor in my car?

My car is a 2003 Honda Element Ed awd auto. I've had a check engine light on my dash for a while and I brought it to a mechanic for a diagonistic scan and it comes out to be a bad o2 sensor. My inspection is due in a few months and I'll have to get it replaced

But my question is what symptoms will having a bad o2 sensor do to my car? Will it affect off the line acceleration, will it affect acceleration at any speed? Will it affect my cars gas mileage and top speed?

How can I overthrow my boss so that I can become the new boss of the company?

I work at a car dealership, but everyone I work with agrees that planes are better and that we should get into the business of selling planes and helicopters. Our boss says that we can't do that because we're supposed to sell Hondas, but we all hate Hondas and want to sell planes. I have an old plane myself that I take people around to ride in. My boss doesn't want me to do the airshows anymore even though I get more money that way. We want to overthrow him so that we can get into the business of selling and servicing planes. How do we do this?
