Recall 90V177000 describes the problem with my 1988 model. Engine reaces at start up. Not always but more frequently lately. Sometimes takes several attempts at re-start to get idle speed down to normal. Is dealer obligated to fix? The Recall says it's for 1990 models? How difficult is replacing the TPS sensor(s)?
