Ive changed my plugs multiple times and still can't solve problem. 93 touring, stock turbos, full exhaust, intake, pfc, avc-r boost contoller. Car smokes a little on start up, but once warm no smoke. runs decent when slightly warm. But when at norm or higher operating temp performance highly degrades, idel is very shakey at 180 degrees fahr. What could be causing my car to run like this, Thanx in advance for all the help.
