Seriously, it's just not worth short-cutting this one.
I was having this problem when i bought mine. Its the reason i joined.
I replaced the IAC the TPS then finally the CPS and now its fixed.
Everyone says they are a PITA, but it took me about 10 minutes.
I used a 12" (i think) extension and a 11mm socket (i think) on an air ratchet and got the bolts off without any trouble at all.
All in all it was incredibly easy for me and I'm no mechanic.
