Hoping someone can help. My '95 Maxima SE with 159K on it has developed a rough idle. Symptoms are: Starts up just fine (no cranking), idles almost normal in park or neutral, in drive car idles very rough (rock and roll), on acceleration car 'dogs' until about 25 mph, after that seems to run normal until slow down under 25 mph (idles rough again at stop signs). The check engine light is on.
This same scenario occurred about 2-3 months ago. I put some fuel injector cleaner in the tank and the next half day ran rough, but cleared up. Have not had any problems, until yesterday. Tried injector cleaner this time, but has not helped. THANKS!!!!
