Heres another, I have replaced TPS, MAF, IACS, cleaned TB, and still, can't seem to get it ideling constant. It will run good for awhile, sometimes a whole day lol, but I'm always having to tweek the TPS and screw to get it back. It does the up and down idle. I have reset the learning many times, however, I have removed my cat and have a magnaflow muffler which might have a slight leak... I've also checked vac hoses...
thanks
