There appear to be to be some widespread concerns among Nissan Maxima house owners who have the 2000-2004 models. These tend to variety from intermittent rough idle to documented transmission problems, to a drastic lessen in overall performance. We are searching in to the real result in of the issues, and offering our guidance on what to do, and what NOT to do.We seemed into how to troubleshoot the intermittent rough idle issue in the most up-to-date report. It can be attributed to the ignition coils, which have confirmed to go undesirable in the initially few decades of ownership. The upcoming challenge we are heading following is the supposed transmission problems I have been hearing about. This issue has been defined as a hesitation in the shifting from 1st to 2nd, or 2nd to 3rd underneath 50 % to entire throttle. It also will cause hard shifting, and the look of a "rev limiter" all around 4000 rpms. The TSB (specialised provider bulletin) out for this says that the solenoid control assembly in the transmission is to blame. This assembly is dependable for the accurate shift moments for the transmission. Sounds like the ideal response, correct?Possibly. These handle assemblies can go negative, but it is only because of to the construct up of debris in the transmission method. This particles comes from clutch material and burned transmission fluid. With that a lot clutch substance worn down, you would most probably have some slipping in the transmission happening. If it is in truth slipping, then I would look at a transmission rebuild or substitution. Basically replacing the manage assembly would just delay the inescapable, and price you 500-750 pounds.The challenge I have described is NOT the transmission. I repeat. NOT the transmission. In my illustration, I have not described any slipping of the transmission. In a lot of circumstances, this "transmission" symptom is accompanied by a pinging motor and lower efficiency. This is most likely a fuel associated issue. The ping is from a lean gas mixture (not adequate gasoline). The inadequate functionality could be from the same result in. If the knock sensor or the trans solenoids were terrible, you would sooner or later get an engine difficulty code from the European/TCU. The first area to test is the fuel filter in the gasoline tank. There is not an exterior filter on these cars and trucks, and that filter in the tank is Rarely transformed. The new filter should repair the engine ping, the functionality troubles, and the "transmission" form indicators. The "rev limiter" experience is from the engine not possessing adequate fuel to keep on elevating the rpms. The challenging change is from the transmission anticipating the speedier change needed at larger rpms, but the engine is not accomplishing accurately, so the acceleration is not there to comprehensive the smooth change. All these programs get the job done intricately alongside one another. Decrease the gas stress accessible to the injectors, and all of the higher than symptoms can happen.Be convinced to have the codes checked. In a lot of situations I have noticed, these troubles come and go with no check out motor gentle. That is a good indicator it could be the fuel filter. You may well also have a dirty throttle body, which I recommend cleaning when you exchange the filter.Fantastic luck, and stay TUNED!REFERENCES:http://www.newarticles.us/article362907.htmlhttp://www.thearticledatabase.com/article.php/04-09-2012What-You-Need-To-Know-About-Car-Fees.htmhttp://www.articlerich.com/Article/Understanding-Your-Car--s-ECU/2375441
