high idle on startup and refusing to rev

[CarpeNoctem]

hey the 93 loyale (spfi) is running and driving now, but it wont rev past maybe 3500-4000. if I give it any more gas it starts to lose power.

 

vacuum readings are good (sitting at idle I don't have an on car gauge)  

Ignition timing set to 20* with timing light.

 

if that weren't enough the idle is about 1300 cold and takes about 4-5 minutes to go down to a normal level and then it drops very suddenly and sometimes likes to bounce around a bit occasionally. I figure I need to take a look at the IAC valve and clean it up, but with how fast it drops it may need replaced completely. 

 

any thoughts? I'll be testing the tps and etc tonight trying to pin the reving issue down.

looking into old posts the idle may be coolant temp related. haven't done it yet and the gauge doesn't read at all so I may not be getting any signal from it. another of tonights to do list items.

 

 

also it looks like the cts could be an issue so that's getting done
