Well I've found what was wrong with my car!!!! It was TPS , but it was working only for percentage of opening throttle and not working idle switch. This caused ecu to inproper fuel and timing operation!!!! And there were no eror codes on ecu. And seems to me I also in need of new splitfires. Because engine work not so smooth on high load of boost. Good luck you friends to find out yours solutions.

Well ... the weather outside is weird so I've desided not work with my car but find out any solutions to described problem. 1. I found that Crank Angle Sensor replacement helped to solve problem. will replace with one from working engine. 2. Also I suppose it might be problem with Intake Air Temp sensor failure, because after short run engine heats up and problems occours from 1500rpm, but on such low rmps it much harder to hear. 3. I also planing to check every relay , maybe something wrong there. 4. And at last main engine wiring harness...check for any cracks As I suppose my problem not actually missfiring but "rich & retard" causing missfire. Or possible too lean ..... but I don't know how to find out am i runing rich or lean. Any thoughts or suggestions ?

I've already tested my O2 sensors and AFM's and they work perfectly! I've tried different gap on my Apexi 8 plugs(0.8 and 1.0), it's not matter for me at all! If anybody with same problem could test main wiring to find out any crack there it will be great! As for me I dont know any special trained mechanic to do this for me fo cheap so I'll remove main wiring and check it by myself for free. And of couse I'll inform you 'bout my progress .

I've already tried install the set of NEW SPLITFIRE'S but it's not helped At last I'm thinkig of problem in main wiring of engine. Today will try to find out any cuted wires from ECU to engine. My friend got problem like mine and he found some wires were cuted in main wiring!!! Looks like Nissan makes their cars from some junk or shit! I don't know exactly but it seem to be like this!

hi to everyone! I've expiriencing the same problem on my R32 GT-R, engine missfire after 4000rpm ander full load(boost 0.8 bar) and engine cut off after some time if I keep running . But I can't solve this problem. I've already tryed to replace ign coil from 3 cars and they was runnig smoofly. I found that where was problem with wiring jaker of the ign coils, I removed jakers in conect wiring directly and sealed with silicone, esterday i sealed ign coils like you did, and engine start working well but only if I run on under 1/2 throthle. In other words main problem still remained. before any work on this problem i found that #3,#4,#6 cyl were not working properly. and even after exchanging coils 3 times they not worked. after fixing connection jaker of ign coils -- #3 and #6 working OK, but #4 NOT spark plugs - set of new greddy 8 plugs (gap 1.1) power transistor - was replaced new fuel pump injector were cheked and they are OK and now i want to ask you what else can cause missfiring on RB26DETT? Well, looks like i've described my problem and now I'm waiting of your advises on how to make my godzilla run like mad! and please excuse me for any mistakes in english it's not my native language I'm from Russia Far East.
