Unhappy Total Loss of Power

Hello, Forum

Within the past 3 months(about), the car will turn on, and have zero power and just not accelerate. I can literally floor it in neutral(I have a 6mt) and the revs will climb very slowly. They'll climb but extremely slowly. In gear, the motor will rev, slowly, but the car will not pick up speed at all in any hurry. I floor it in every gear, and it is the exact same in every gear. In other words, I can floor it in 1st, 3rd, 6th and its the same speed of rev climb and acceleration. I'll list my mods below.

K&N drop in filters, silicon air intake tubes, test pipes, stock y pipe and single exit exhaust after. No tune.
Always been very diligent about maint. and oil changes being done every 4.5k miles on full synthetic.
There are no strange noises from trans, rear end, motor..nothing. No spots under the car after being parked.

I do currently have a slow coolant leak from somewhere. I'll be taking it in within this week, but I wanted to discuss my problems with the forum and see what input you all may have for me.

As always I appreciate your comments.

Best,
Banshee

P.S. I do drive it very spiritedly. But by no means in a rude or harsh manner. I've only ever done donuts in her one time, and when I learned from experience that I could not do straight line burn outs without axle tramp I stopped ever trying anymore. The car has been to the track once and I only did 4 runs(about 5 or 6 months ago).
P.S.S. It is a Texas car to give idea of weather. I'd say about 95% highway miles.

No check engine light or low oil pressure light? Oil level is good on dip stick?

Check light is on but it's due to O2 sensors sensing no cats. No oil light thank heavens. Oil level is perfect I checked it after 2 days of sitting on a flat surface.

I would be curious to see what your fuel pressure is reading.

Does that cost a lot to have it checked?

Check engine light might be on for a variety of reasons. It sounds like you're in limp mode b/c of a serious code being detected.

I'll get the code checked again but most recently it was just o2 sensors. Will report back with what I find.

K&N can goop up MAFs pretty well if over-oiled, which is super eye to do.

Maybe a $8 can of MAF cleaner is in order before biting off too much more?

Had a very similar issue on an RX350. Neighbor was helping my wife jumpstart the car (while I was out of town), connected the cables backwards and blew the traction control fuse. Nearly NO power at all. Engine ran fine, but would not lay any power down. Replaced fuse, 100% fixed. Do you have any other dash lights on besides the check engine light??

Well I took the car to the mechanic. The leaking coolant was from a broken water neck. Warranty covered it thank god. As far as check engine light and loss of power they report no new codes and that the engine may have sensed low coolant and went into limp mode. I will have her back after the holidays.

There are no other dash lights on.
