Thread: siberian guy need your help

no look at the knock sensor log to see if there are events stored. The coil pack is a ignition problem I have seen on certain nissans and they create this sort of issue when the coil pack is going bad. If you are running lean I would start by checking the maf to make sure it is functioning with in factory specs. I would then check the fuel pump. Although the fuel pumps in nissans are usually really good I had one go bad on my in laws cefrio at 6,000km. Access to a consult II will allow you to trouble shoot the car using the CAN communication system that is built in. Some times error codes do not come up until the event happens several times with in a certain amount of engine cycles. this can make it very hard to trouble shoot a intermittent problem.

today found interesting thing - I have no "coil pack" problem with "override off" but may be it's just a good luck

one guy have just replaced kick sensor - but result the same, may be problem is in CAN, but how to check it? on the 98 gasoline this problem happened less than when 92 fuel is used

who actualy have manual for SR20VET motor? would be helpfull to read

I've never seen one, closest I've found is a P12 "20V" SR20VE service manual as this has a similar ECU & drive-by-wire throttle setup. You can find the manual here

please tell me how to check CAN bus? how we can do diagnostic signal transfer throuhg CAN and that signal transfer is correct?
buddy took CPU from QR20 x-trail for replacement, when he connected it - car was more faster than before, he reach up of the hill with switched on conditioner (slope 15%) in some seconds, but after 35 minutes, new CPU has adapted, and car became as before (with coil pack problem) he restarted CPU, switched off power - no result!
his ideas now - to replace our ECU sensors or send our CPU to Japan or Malasia for reprogamation, what do you think?

you need a consult II or a consult II program to use the can bus system. you can get a consult II program for you laptop off ebay.

hi, everybody! I came back with some better results, I've replaced intercooler for frontal one, installed apexi air filter, changed exhaust pipes, and installed autronic ECU. but to further increase power of engine I need to tuning my automatic transmission, do you have any idea concerning this?
