2G Throttle Body/Idle Issues

[DeceptivePerfor]

I recently purchased a 96 GST and am wrestling with the DSM Gremlins. I have an issue where the Idle starts out fine then eventually keeps rising. It normally goes to around 1500RPMS. Today I stopped and filled up the car. When I restarted it, it shot to 5000RPMS. Usually when this happens (1500-2000) I just pop the hood and tap where the Throttle Cable attaches to the TB. Today, I noticed that the spring seemed extremely loose. I tried to remove the TB completely this past weekend but, could not get the three lines at the top to come off. I have sprayed Autozone Brand WD40 to clean the TB.

I have don e research and cannot really find anything on tightening the spring to see if that helps. Maybe tightening or loosening the Throttle Cable? I do not wish to eliminate my Cruise Control. Any help would be great. I want to try and troubleshoot this before I go into rebuilding or buying a new TB. Any help would be appreciated.

are you talking about the three little hoses?

Yes, I tried pulling them off and the would not budge. I did not want to yank too hard and rip them apart. I imagine that they are as old as the car. I want to replace all the hoses, lines, etc... eventually. Today is just not that eventually date that I had in mind.

well if i was you id use a flat head screwdriver to push them out... in the mean time id suggest getting new hoses.... there pretty cheap...!

Ok, that still does not explain my Idle Surge Issue which, I am convinced has to do with the spring or cable. Anythoughts on that?

ok take the intake pipe off the throttle body elbow.... then inspect it.... when you pull on the throttle cable and let go make sure that it closes all the way... and/or adjust the throttle cable...!

So, I adjusted the bracket for the TB Cable. I cannot belive it but, it actually worked. See, I was thinking in terms that metal expands with heat. So, does anyone have any info, guess, or ideas how this remedies the problem? I traced as much as I could and just do not see how it could tighten with heat. It goes against science.

I am glad that it has seemed to remedy the problem. Anyone who has an idea why heat is causing the metal on our cable to contract, let me know,
