NOTE, SEE MY POSTS #482,483,493. I still have  a problem with my 2.4L but it is now worse. I coudn't get an error diagnostic code but it would start and get to 2700 rpm then fall back to 2000 and try to rev up again. I disconnected the 0-2 sensor to see if that code would show up. Now the thing tries but won't start and run. I added gas down the intake and still it tries but wouldn't keep running. Now this is scary, I pulled all of the injector connectors and tried it. I ran for almost a minute. This tells me the injectors are suppling too much gas and the engine RPM falls down. There must be sensor that tells the ECU that the mixture is too lean and to increase the gas supply. I haven't found out which sensor that is but this could be the original RPM problem. Too much gas will cause the engine RPM to decrease. If I find out I will let you know.

my 96 2.4 does the same thing and the only thing i havent replaced is the crank angle sensor, but it is one piece distributer and all. dont have 250 dollars to buy new one and try it, they cant just test the distributer, need the whole truck running. mine runs great to 25-2600 rpms, acts like it hits a rev limiter....any luck please let me know as well. much appreciated.....danny

My 2.4L has the same problem but my mechanic did replace the dist with a brand new one and the problem did not change. I have since determined the problem is with the fuel injector pulses. They are allowing TOO much gas to be injected and the engine won't rev past 2700. I did find a broken wire going to the air temp sensor. Repaired that problem but now it won't start and continue running. The air flow meter(MAF) as it is called on my 93 may be the problem but haven't got back to trying to troublesoot that component. At one point after many starting tries I disconnected all four injector connectors. It started and ran for 30-45 secounds. I had put gas down the intake. When I tried adding just one injector it died. Still fishing for answers. No computor codes have ever shown up. Good Luck

thats an easy one,mine did the same thing,it was a bad sensor on the transfer case, its an easy fix...ive been a professional mechanic for 16 yrs. now and that seems to be the norm w/ nissans

im a mechanic in a reputable garge and ill give u an idea if u need one...usually when u can unplg the injector harness and the vehicle then starts and runs,until the available runs fuel out, that is a sure sign that either the comp. has your injectors wide open, in which case youll need to replace the comp., or you got a short in the injector harness, and thats alittle more time consuming,but thats where id start my search..most dealerships can test your comp., forlittle to no charge if u take it out, but call the dealer first cause some cant test them unless they are in the vehicle.and usually you can pick up a cheap harness at a salvage yars at a reasonable price

i see this all the time,ive been doing auto repair professionally for 16 yrs.the only you need to worry about your timing belt is during the reg. scheduled intervals. the manufacturer gives maint. times and specs because they really do work..if your truck doesnt have an oil leak up frt. around the belt housing then chances are youre still good till your scheduled time,but if you are a worry wart,than changing your belt early wont hurt a thing,just to inform you,not scare you, if you have an interference engine than its a good chance that IF the timing belt broke,for whatever remote twist of bad luck, then its almost guaranteed that catastrophic engine failure WILL result,ie,the valves will make contact with the pistons and usually the cylinder head cracks, the pistons are destroyed from grooves, nicks,and shavings, and the cylinder walls themselves depending on engine speed or RPMs,will scar to the point theyll need bored,or the engine block replaced,ie a whole engine replacement...this is a worst case scenario.let me know if i helped.

my 95 d21 just did the same thing,it was actually the little condenser on the back of the alt. by the way,if you takr the alt. out from the bottom it is so much easier.if you dont know what a condenser looks lie,its 2 inch long, about the diameter of a nickle and has 1 wire coming out of it.after that i havent had any trouble out of it.

check the main fusable link.it comes off the alt/ starter circuit as a main power source to the cab its in between main hot batt. cable and chassis harness to the inside.

is there a engine temperature sensor anywhere close to your distributor? if so then it maybe bad,when its cold its calling for so much fuel that its actually flooding the engine [in the computers eyes] in reality its not, so the comp thinks its flooding and shuts down the injectors to stop the flood situation..so when you put the hair dryer ie, heat, either on the dist. or in close proximity to the engine sensors, the comp. reads as normal and the truck starts.

a rough ride, excessive play in the steering wheel.if you jack the frt. of your vehicle up and support it properly, have an assistant help,you can watch the balljoints movement if the assistant places one hand on top of the whl. and grabs the bottom of the whl. w/ the other, youll be able to see any movement in the upper or lower BJs, if the assistant tries to pull out on the bottom and push in the top of the wheel alternate between the 2 actions [push,pull,push ,pull] and if your assist. does this corrctly youll see them move.the same holds true for the tie rod ends and other frt. end components except swap positions of your hands from top and bottm to one on each side of the whl. one towards the back of the truck and one towards the front, doing this youll be able to see excessive movement in 90% of your frt. suspensionas far as frt and rear SHOCKS,no struts on our trucks,thats all in the ride and stablilty,rough ride,swaying motion[dog walking]these are all common signs of bad or failed shocks,and sometimes stabilizer bar link pins and bushings. i use TRW suspension parts for normal vehicle use,they are affordable and extremely dependable, plus the warranty is really good and they have no issue honoring it and as shocks go monroe has a very good and wide array of medium to heavy duty shocks at a very cost effective price but try to stay w/ a medium duty shock to keep the ride firm but not kidney busting,but for extreme sport usage youll have to go to 4X4 offroad application which youll have to research,i only use mine for normal things [hauling,pulling,pushing etc.] hope this helps
