I have a 92 lx. I bought it built. b cam, gt40p heads, mac headers, explorer intake, bbk cold air fenderwell, 70mm tb, tb spacer, msd, under drive pulleys. I have to feather the throttle first start up. It idles rich. When pulling up to a stop light, sometimes itll idle 3,000, somtimes 2,000 rpm, you can rev it and it usually dont change it. sometimes itll idle at 900 then just idle up to 3,000 with no one around...... What should I do? Where should I start mainly? Thanks... (I know this is probably answered already but I'm irritated and don't have the patience to browse...)

Possible TPS problem, dump codes and look for codes 23 or 53 or 63. See the link below for dumping codes and finding idle/stall problems.
See the "Surging Idle Checklist” for help with all your idle/stall problems. You can guess at the problem and throw parts at it, or you can use the checklist to help you find the problem quickly and inexpensively. The checklist is right here in the Stangnet 5.0 Tech forum and you don’t have navigate to some other unknown web site. It‘s free and doesn’t cost anything: at last count there were more than 103,000 visits and still climbing
The quick and easy way to dump the codes is in there too, and all you need to do it is a paper clip! The first two posts contain all the fixes & updates. At last count there were 24 possible causes and fixes for surging idle/stall problems. I continue to update it as more people post fixes or ask questions.
