The pictures work fine for me from my home computer. The firewall at my workplace blocks sites like www.Photobucket.com where the pictures are stored. If you are viewing them from work, you may have a similar situation.There are some pictures missing in the beginning of the post. First page of this post. Can we get those fixed? Would be helpful.
Thanks!
Setting the TPS at .98 or .99 volt is a Bozo Internet Myth. When the computer powers up and initializes the TPS sensor, whatever it reads is the zero starting point for it. In other words your .98 volt becomes 0 volts and the computer watches for increases in voltage from that point upward.In regards to the tps, is it possible for it to be on its way out and causing hanging idle issues but still read correct voltage throughout the idle range, starting at .97v closed throttle?
Flasback87 said:When doing the base idle reset I have my idle set to about 600 (stock tach) with the engine warm, iac and spout disconnected. So, when everything is connected it idles between 6-700 rpm's. But the idle sounds very week and I have to give it some gas to keep it running on cold starts. When it is warm it is fine. So, I raised the idle a little with the idle set screw. Now it is idling around 7-800. It surges most when I am coming to a stop. If I am coasting to a stop it will surge until I completely stop (I hooked up the vss wire in my maf conversion). Then when I am stopped it will idle fine for about 10 seconds and then slowly start to surge. I did get a couple iac's from the local pull a parts and I am running one of those now to see if it fixed my problem. It is idling a little better with the different IAC but not completely w/0 surge..
Try trimming the gasket to open the area between the 2 ports. Do a little bit at a time and see how it works.does any one have a good picture regarding opening up the port on the iac with a dremel to allow engine to idle higher? it was mentioned in the very beginning of the post.
Possible vacuum leak. I had one recently that turned out to be a missing cap on one of the spare vacuum lines.I soaked my iac in a can of gunk and I raised my idle because if I set it at 600 rpm doing the base idle reset I have to give it gas to start and keep giving it gas to stay running for about 30 seconds. now it will start on it's own but the idle is at about 1,300 rpm when coasting to a stop and when I am stopped it is at 1,000 rpms. it doesn't really surge anymore but why do I have to have it set so high? It use to idle at 7-750 rpm's with now surge which made my cam sound really good.
any ideas?
Thanks again!
Yes, replacing the TPS is what is needed to fix this problem.That pretty much describes my issues in full. So what is the solution? A new TPS?

Don't you feel the pain in your wallet already?
See the TPS setting procedure in the first post of this checklist to set the new TPS.
Thanks, swapping for a new one today. Does the engine really need to be at operating temp to set the TPS?
