Because the car has adaptive technology, it may take a while to reset and adjust to the new, cleaner and better conditions than those to which it had previously adapted.
Did you change the cap and rotor? if the plugs needed replacement, likely they do too
Possible other causes include:
loose or corroded connections to any electrical component you disturbed (make a checklist and tick them all off as you check them);
mis-reinstallation of any F.I. part disturbed(checklist again)
obstructed water flow through the AIC valve;
improper voltage output from the AIC valve (for LH 2.4 systems, should output 8 volt at idle, dropping as load increases; for LH 2.4.2 system output 7 volt at idle etc; testing between terminals)33 and 17 at disconnected LH connector;
possible problem with MAF.
Hope this helps

Most likely your throttle position sensor is faulty. You could have a vacuum leak as well. Most probable cause is a bad sensor. Is your check engine light on? Have you checked your engine codes? You can go to autozone.com and register for full free online repair manual.
