99 4Runner won't idle
My 99 4runner 3.4L V-6 has 220k on it and has not needed any repairs - yet. Burns NO oil and no leaks. All is original except the MAF sensor, both O sensors and TPS, all replaced within the last two yrs for emissions. This evening, after driving 100 mi roundtrip to work today, I ran in to town and when merging on to highway, tromped on it and got it up to 80 (and near redline). After that it has not idled at all. The only way to start it and keep it running is to have foot on gas. What's up with that?? Looking at linkage while running, the linkage doesn't even try to regulate the idle, it just dies. Help!!
