94 25th weird idle

Hello, maybe someone can help me with idle in the car I just bought...94 T/A 25th Anniversary 101,000 miles bone stock.It idles perfect in Park but hen I put it in drive and hold my foot on brake the RPM's fluctuate and jump every couple seconds . It will rev up to maybe 1000 rpms and I have to hold my foot on the brake real hard. It started powerbraking in my gravel driveway today just idling.....Also, if I let off the brake and just idle the car will go 15MPH. I thought that was kind of high. I just cleaned the MAF sensor and installed IAC valve.I have a video on my phone and email that I cant seem to get on here of the tach if anybody wants to see it maybe I can send to them. Thanks alot

Update on this if anyone cares....I found that the previous owner had the disconnected the ECT sensor.. I plugged it in and it starts and idles perfect. The SES light went off too.
I dont know why he would have disconnected it????
