I feel like Im losing power. I recently just changed my spark plugs, cleaned and re-oiled my K&N, cleaned my MAF sensor, TB, oil, fuel inj. cleaner, and disconnected the battery trick.
What I found was odd, is my tranny was flushed about a month or so ago. I checked the fluid, it was a quart low. I added a quart of Mercon V (obviousy.) The performance got better, but not what it was.

Im running out of ideas fellas. No MIL either.

EDIT: And once in a month or two while cruising at 50-60, if I let off the gas, the car acts like its downshifting and bogging down. When I put my foot back on the gas, it jerks and goes back to normal. Does this make sense?

Your getting the Mustang flu...Your car is getting old to you and you want it faster..lol I think we all feel like that sometime...Hopefully nothing is wrong with it. Good luck.

So it was after the flush when thing started to go bad?

Haha, no bud, that's not it. Ironically enough, it's starting to get cold down here in Houston and its not "feeling" faster like it should. It's running like it's 100+ degrees outside. It's throughout the entire powerband, not just down low or top end.

hmm its a auto?? btw beatutiful looking dropt top, mineral grey is one fo the ebst colors, had it in my old 02 gt, looks awesome with bullitts...in any event, were the plugs gapped correctly? and when u let off the gas the car bogging sounds like the Idle Air Control, i would get that checked out.../clean it out to see if that helps, uhh do you have a check engine light on? exhast with no cats?

Didn't start happening until about a week ago. The flush was over a month ago.
I looked under the car and there seems to be some tranny fluid around the tailshaft, where the driveshaft connects.

Common on alot of the stangs, my buddies 01 bullitt has it and a few other 99-04s ive seen, it seems common, is the car an auto? sorry if i am missing that

Thanks bro. I love your style Cobras as well.

Yes, it's a 4R70W.
The plugs are Bosch Platinum 2's, no need for gapping. I always run this plug, no issues before. The old plugs looked just fine.

Flowmaster cat-back, stock midpipe and manifolds. (for now)

No engine light.

I'll check out my IAC.

OK^^and thanks, i love it, she doesnt treat me 100% all the time, but she is my dream car, and yea check the IAC, if not, get some mods maybe, but not being stupid about that...because i know you want ti to run normal...have you driven it since?? cause some days my car moves out real good, like vette killer good, and other days she just has ***** and thats it...but tranny slip at all? check fluid level again i guess...just throwin ideas out there, hope it helps

I'll check the IAC. What is the best way to clean it?

No slip at all.
