randomTL

Tryin to figure out what the heck this may be. I have a 99' TL. I'm not getting any check engine lights, but the problem is slowly getting worse over the past year. Here goes. It seems to happen mostly when the car is cold or warming up but when I accelerate from an idle the more gas I give it the more it hesitates. Also, when I turn a corner I let off the gas to brake, then try to accelerate and it wants to hesitate. Seems to idle fine, and after initial hesitation it runs great all the way to redline. When it warms up it doesn't seem to do it near as much. So far I have replaced plugs, o2 sensors, MAP sensor, cleaned intake, and EGR port, and run tons of fuel injector cleaner including directly into intake at oil change place. Without any CEL lights I don't know what else it could be. Any ideas? Thanks.
