I have already set it to 1 k and I have checked closely for vacuum leaks so... WTF any help would be thankful... BTW the TPS setting before adjustment was 2.4 k!

This happens to me too...starts at around 2k, then drops to 1k, then starts bouncing between 1000 and 1500 for a minute or two. What gives??? BTW all vac line hoses have been checked, most replaced about a month ago.

Make sure the coolant hose that travels to the choke are not clogged up. Especially the aluminium extension on back of the dynamic chamber. If the thermo choke doesn't get any hot coolant your idle will not come down. Ill keep checking this thread and trying to help..

I understand the car idles high cold, my N/A goes straight for 3k at startup, sits there for 15-20 seconds, then comes down to near normal, maybe a few hundred high at 1200. My problem is that the idle is bouncing about 600 rpm, like if you were to quickly punch and release the throttle. This happens after the car's been running a couple minutes, when it's about halfway to 'warmed up.'



I'll check the coolant lines, thanks for the tip, Judge Ito.



needa86NAat - Hope I'm not pissing you off by posting my problems on your thread, I feel like we've got a similar issue and I don't want to create clutter asking the same things somewhere else.

mine does the same awful business. idle surges up and down. doesnt help that the intercooler covers everything that you need to tune to get it to run properly

My 86 na auto bounces at idle sometimes, even when warm. I have no idea why but it sure gets old.
