Thank you FRO, I think it has a thermostat as I’ve put a temp gun on the head and it reads 185-190 so I’d assume there’s a thermostat. I’ll have to do your test. If I remember correctly when you first start it, at dead cold, it does high idle around 1100rpm and slowly comes back down to ~850rpm. So honestly I think cold start is fine but that still doesn’t rule out why it high idles when you come to a stop after cruising, but then slowly goes back down to a normal idle when you sit there for a a minute. Plus now I still have to figure out why it doesn’t idle at all unless I’m on the gas pedal. Thank you guys for the responses!

New problem… got the injectors and clips, took off the Tb, cleaned everything and put it back together along with all new vacuum lines. My problem now is it won’t idle at all, and misses unless I keep taping/pumping the gas pedal like an old carb. But it revs perfectly and sounds good. I’m stumpt… Another thing is when I took apart the Tb and took off the Idle air module, the screws looked like they were overheated to hell. They were all discolored like bluish, purplish. I’m still having issues with my coolant temp gauge as well as the actual temp sensor for the ECU I think. Because it smells like it’s rich which could also be my problem with idling. Anyone have any suggestions? Is there maybe a common ware spot for wires for the coolant temp sensors? Also if the thermo valve controls vacuum for cold/hot and with the coolant temp sensor for the ECU (maybe not working) could this be a problem for my idle issues? Thanks!

Awesome, thank you!

Yeah, it’ll rev pretty good not under load. It’ll rev to around 5500 and does the stuttering a bit. But as soon as you put it back in gear won’t do anything past 3500. It seems to be the worst in 2-5 when the engine has the most strain on it. thanks!

No it acts as it hits a barrier. It won’t do anything, doesn’t build boost just stutters till you let off. I’ve put a vacuum pump on it and it holds vacuum just fine. thanks for the response!

Do you have the link for an 86? Thanks!

Ok thank you for the suggestion. I’ve deleted the AC as I really never use it anyway. As for misfires, yes… I have a problem with when it warms up it starts to misfire kinda, barely noticeable but still there, then when I try to hit boost it totally falls on its face around 3500 rpm’s. I have clips and injectors coming to hopefully fix that problem. thank you!

Hello, I’m new to Starquest’s so maybe someone can point me in the right direction of my problems. My coolant temp gauge seems to work but very little. It usually goes just above the line above “cold.” Then when I start driving it goes to just about cold. If I sit still and rev it (instead of idle) for a little while it’ll start to get to the middle where I’m guessing it’s supposed to sit. I’ve replaced temp sensor for gauge and kinda looked over the wiring. Everything seems good. Is there a ground that could cause my problem for the gauge itself or should I go through the whole harness? Another question I have is when I am driving and stop at a sign or light it’ll high idle around 1,200 rpm like it’s ice cold (which the gauge says it is but I know the gauge uses a different sensor) but drops back down to ~850 rpm after sitting for around 20 seconds like it warms up a bit. Could this also be a wiring problem? I’ve also replaced the temp sensor for the ECU. I have checked the head with a temp gun and it says about 185-190 so I know the thermostat is working. Any information is appreciated, thank you!
