So hears the problem I have put a new map and tps sensor in and still the same problems slow acceleration to the point of bogging out. I have even clean the IAC and the hole throttle body still sluggish off the line I have the 4.0 with a 4.5 and 33s on it I've read a lot on it and still can't figure it out this is my first jeep I bought a new IAC sensor and put it in and made it run worse so I put old one back in that I also cleaned please help jeep community

If you still have the stock gearing and running 33s, it's going to be very sluggish. You should check the fuel pressure though, low fuel pressure will hamper performance. But really, 33s+4.0+3.55 gears= very sluggish acceleration. I'm living that dream now with my ZJ.
