Hello,
I have an '88 T-top that the tac "putters." It's like it wants to stall out, but when I rev it up to about 2k rpm's, it is fine. It does it completely randomly and only does it for a maximum of about 2 minutes. Sometimes it will start puttering as soon as she's started and other times it starts after driving about 8 miles.
It was suggested by a friend that it could be the coil, so I bought a new one; same issue still occurs.

Thanks in advance...

could be a dirty iac valve- idle air control valve ,the big round thing sticking off the throttle body, soot and carbon on its seat can make a poor idle condition , get some new gaskets at a parts store remove the throttle body , and all the componints and clean them use parts cleaner or wd-40 works good to clean grime also, dont use carb cleaner that stuff eats through somerubber , and may destroy o-rings , a blow gun works good if you have a compressor, or if not just wipe with a clean rag and reasemble
