since your car is an auto...then usually it takes awhile for it to kick in on a roll...but from a stop, it should be fine

try resetting ur ecu, could be a cold air intake thing, perhaps it needs to readjust confused

CLean your MAFS and reset the ECU. If that doesn't stop the sluggishness, put your stock airbox on and reset the ECU. If that solves the problem, then it's your intake that's causing the problem.

If it's not the intake, the only other thing it can be is your first O2 sensor. It'll also make the car read lean if it can't read temperatures properly.

I'd still throw on the stock airbox for a week and check to see if that does anything. It works for almost everyone who has had problems with bogging/sluggish acceleration with their aftermarket intake.

i have the AEM intake, if I might ask blue bomber what causes bogging in an air intake. does that mean the ECU needs to be tuned confused

Well, you can solve the problem either by getting a replacement/piggyback ECU that can reliably alter AF ratios (not Apexi S-AFC), or modify the MAFS' environment like this:

new[/b]celica[b].org/forums/showthread.php?s=&threadid=127861

Either way will stop the car from running too lean. Every intake out there except the TPR CAI is poorly designed, which is why you see lots of people out there getting bogging and P0171 CELs from them.

I had this problem too, Toyota was not able to diagnose it.

I changed plugs, higher octane, lower octane, air filter, cleaned the throttle body too. Nothing made a difference.

I found it was kinda "bottoming out" when I first put some gas to it, like it would pause before it gave me anything.

This started happening shortly after my wife took my car to Crappy Tire for an oil change (she now knows this is a bad thing) and they cross threaded my oil plug and it was leaking all over the place.

I don't know if it was related or not (maybe the oil pump??) since my engine has now blown.

I had the same problem with my 2002 GTS. My MAS measured good electrically but I found out the sensor was dirty.

Either your MAS is dead or you cleaned it wrong.

Spray on residue contact cleaner into the MAS' cavity with the 2 electrodes, also the brown thermistor blob. Let it soak in a few minutes and blow it out with an air tool. That should clean it up.

Drive the car aggressively a week for ECU to learn your driving regime.
