If you have an 86 and there are some miles on the car, you need to change the IAT. Intake Air Temp Sensor. When they go bad the car will run like ass at part throttle and idle. They are pretty cheap too. Around $15 at Autozone, Strauss, Advance etc. The sensor sits in the #5 intake runner on the lower manifold. Screw out the old and screw in the new. That damn sensor went bad on my LSC, Mustang and my Bronco. As stated above you need to set the TPS correctly as well. Good luck.
The iac.... I pulled that out of my intake when I painted it and it never crossed my mind to change that. I'm going to get one in a few. Thanks blkstang for the offer too. You guys are great here. I have been on other sites and and it seemed like if you didn't have 1000's of posts then you q's don't get answered.
Its hard to diagnose a miss without hearing it. What about your ignition? Wheres the timing at? How are the plugs, wires, cap, rotor? How about the coil and module? Clean the plugs, start the car wait for the miss to start then shut it down and pull the plugs. See if they are all black or if it is just one or two.
A few things for me to help get an idea. I had the same problems after my zex install. You changned the injectors are the injectors calibrated to maf. Also, for every 50 shotof nitrous you want a 2 degree cooler plug. Is 10 a little low on the timing, I have a 95 somewhat different but I ran 14. Also, when I had a bad idle, I brought my car inthe garage at night shut the light of and found oneof my plug wires was arching of the header. Just a few things to toss into the conversation. We'll figure it out.
