Hello all. This is my first post on this forum. I thank you in advance for the time and consideration you give to my issue. So, I just picked up a 1987 Ford Mustang LX 5.0, hatchback, 5 speed, all original, 100% stock, 27k miles. The thing looks like it was buried in an air tight time capsule for the last 30 years. Unbelievable condition. Here is my question - the car runs great, starts fine, but does have a tendency to "hunt" a little bit for idle. The issue is intermittent. Sometimes the car will idle at around 1700 RPM and other times it idles around 800 RPM. The other thing it does which is extremely annoying is . . . sometimes when you are shifting up, when you push in the clutch and take your foot off the gas, the RPM's will increase. I love the fox body mustang it was on my bucket list to own one, but I'm not sure if this is normal behavior for these cars or what. So far, I've replaced the IAC, adjusted the TPS to 0.93 (it shows 4.7 @ WOT), and OBD1 shows no issues, it's a clear scan. If you were in my shoes (I'm not a gearhead - I can wrench on my two stroke dirt bike but cars are out of my league), what would you do? Thank you very much for your time and consideration to my post. I can post photos if anyone is interested.
