Engine Performance problem
2001 Nissan Altima 4 cyl Two Wheel Drive 60148 miles
hi ! 2carpros
this car got a engine performance problem. When the engine is warm up, the idle go up and down, it wont stay on a centian speed, when the idle starting to go down it start to run rough, sound like incomplete combustion, of one cylinder and if you check the tail pipe you will hear poping sound like a misfire, check engine light come on one time and its calling for cyl 4 misfire. But when the idle go up around 850 rpm it run perfect not rough no poping sound on the tail pipe and it last for one minute or so and idle start going down and run ruogh agian
