Hey Guys.. Thank you all for kind help.. the whole issue caused due to wrong spark plug. Even the agent has used the wrong one. I have download the service manual and read it cearefully. Then they have mentioned which spark plugs should use. It should be platinum tipped one. All the time the tuneup guys and the agents mechanics used the normal one. It is ok with cr12de engine but not with this. Even agents didnt bother to look the engine type properly which I specially mentioned to them. Here what happend. after I posted this I went to nissan agent and explained them what happened. The first thing they said was it should be a problem with ignition coil. Said they need to do tuneup first , if the problem appears again then need to replace all 4 ignition coils. ( which is 3500 each used @ delkanda) Then they did the tune up changed the plugs The problem solved they charged 15,000 for whole thing. But fuel consumption is high ( Earlier it was 11-12 city and now its around 8-10) But I was happy coz the problem has gone. after 3200 km misfire started again. when checking the spark plugs they looks really bad. So I checked the service manual and found the issue. They all have used LFR5A-11 plug which is non platinum tipped. It has to be LFR5AP-11 ( platinum tipped) which is recomended by the service manual. So i bought 4 plugs and replaced old ones. Now Car seems like powered up. No misfires and I am happy. Thank you all for kind advice's.

Nope. Haven't checked the coolant color yet. Coz it already mixed with water and color has changed. ( after changing the thermostat 6 months ago ,persons @ Mot**R*x katubedda filled water for wasted coolant )

First I decided to go there after reading that thread. But as per Don and others advice I decided to go to agents and do a scan. Thanks Niranjan. If this happens again I will go there.

They said they cannot exactly identify which coil is faulty. So the guy @ Arnord Ratnayake mawatha , told me change one by one and check for the fault. A*w told me to do a tunep first and if the problem still exist hey need to inspect the coils while working. I dont know how they do that. Plugs are checked by two persons and told they were in good condition and all worked as same. Lets see whats going on. I will update if there anything new.

Went to the A*W today ... did a scan .. surprisingly no errors , even they cant explaing whats happening. they wanted to do a engine tuneup to start the diagnose. I said no. Then I went to small place at Arnord Ratnayake mawatha ( next to firebrigade ) . the guy also did a scan and found nothing. So he changed the coil packs (all 4) with used ones that had with him. Then the fault has gone. engine was runnig smoothly. so we thought we found the fault. Then he switched back to old ones. ohh god... It also working good. drove from there to moratuwa about an hour ago in heavy traffic. No misfires. Dont know whats going on there...

Today I got the same problem again. Now its gone bad. car is lack of pulling power and even stalled middle on the road. I am not sure if I can go to a garage with this condition. at least to do a scan. really worried guys. dont know what to do.

Thanks MV-5 .

Thanks MasterDon and Fixzit . But the spark plug wires cannot be remove like that. Plugs and coil pack are inside the cover like this.

Thanks Rumesh and Don. Seems like the issue it not that simple to identify. as you all suggest I am going to do a scan one next tuesday. I will post the results here.

Thanks Gayan & Don . I will do the scan first. Will post the results.

thanks Fixzit .. Is there any place you recommend ?

Hi guys, Need a help from you all to find out what happend to my nisan March BK12 . I am really worried about the things happend with it since last month.. here what happened... 1. Around 5 weeks ago I felt the car is not accelerating properly. engine is getting slower when accelerating. mostly when overtaking and hard accelerating. So I went to my mechanic and he said it may be problem with fuel filter. So he removed the filter ( actually the fuel filter, fuel pump and the fuel gauge comes as a combined unit) and adviced me to replace it. since the whole unit is cost around 38k , he advice me to buy a reconditioned one. So I bought a one from a place near attidiya junction. He checked it and fixed it. So the problem solved. 2. after running around 50km , The engine started to misfire.( started to cough ). Again went to the mechanic and he said there may be a problem with ignition. So he checked the spark plugs and coils. he told the spark plug gap was higher than the usual and that may be a problem.( spark plugs are NGK normal ones and done aroung 6000Km) . So he adjusted the gap and fixed them again. Then again the issue seems solved. 3. again after around 200Km engine again started to misfire. but this time it only happens when engine is on ideal. when as long as pressing the accelerator it wont come. When in N. P or D with break , the issue is there... also there is a pop-pop sound coming from the silencer. A attached a video to get a clear idea. Please guys , can you advice me what happened ? and a good mechanic near moratuwa, kohuwala area.

Try to find BK12.. good power and good in fuel... it does around 10-12 kmpl in colombo and 15kmpl in outstation.
