Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.
what is the mileage on it ?
has been tune up ?
have you checked fuel pressure
is the catalytic converter clogged up ?
did this misfire happens suddenly or gradually you start having lack of power ?
is there a check engine light on or is it flashing while driving >
did you have it scanned and retrieved any fault codes ?
please let me know
Thank You *****ASE Certified Technician
ok do that and post the fault codes back here to me
and we can go from there
I m online today from till 12 pm
that is ok, they are good truck they run high mileage :)
running rich could be a stuck oxygen sensor , vacuum leak causing the ecu to add fuel, leaking injector , bad plugs etc... several reasons could be causing that
my experience at this mileage exhaust, catalytic stopped up , but does the check engine light flashes on dash while driving
ok good so we can eliminate these parts, so O2 sensor upstream is switching from 0 to 1v quickly like it supposed too and the back sensors switches slower correct ?
well that is good that will definitely cause that .
inspect that it is connected
check also the wiring to it, if it is and it looks original then replace it clear codes and test drive .
what was the exact fault code number
Pull up ckp & compare the ohm resistance with a voltmeter to the new one and also check wiring using a test light
i sent you diagram , take a look at ckp circuit , the ecm feeds it ground
it could be either of these issues ,you have to test to confirm
I m sorry i missed that ,what do you mean ( CST) ?

Hello my name is ***** ***** thank you for your question.
The original expert has opt'd out cause he felt he could no longer assist you and re-opened the question. I am a new expert and will be here to assist you with your question. Please give me a few to review your question and I will respond in a min.
I saw you had a code for the crank sensor. This is actually normally caused by a bad distributor. The Cam Sensor in the distributor works of a optical sensor and signal plate type of design that if the signal plate shifts slightly, it thinks that the crank sensor is out of reference when it's actually the Cam Sensor. The Cam Sensor is built into the distributor. So the distributor assembly would need to be replaced.
Also I saw you stated that you replaced the spark plugs. What brand spark plugs did you install?
Yes, Nissan's are very picky on the spark plugs. That is why I asked. NGK's are the correct plugs to use.
Not a fan of after market electrical parts. But that is really your decision. The Nissan ones I know are fairly costly. But do work best. Figure you got over 200k miles on the original.
As for the exhaust manifolds, See if you can get it from the dealer. If not available, see if it is available after market or check on Ebay.
Do you have any more questions on this?
You got it.

Reman from Nissan is good.
distributor changed and still have issues? Is the bogging around 2k rpms?
Did you change a knock sensor? Do you have any new codes?
You have the primary catts, which are after the exhaust manifold. Then you have the secondary catts after the primary catts. So which catts did you hollow out?
Do you have a scanner that can graph 02 sensors? It could be that they are clogged, but when you have more pressure after 3k is when it can flow past the restriction.
Let me know..
actually since the exhaust goes into a Y pipe, you won't loose much back pressure. I have seen them run with everything gutted
If you have any more questions on this, please feel free to ask.
If not, and you're satisfied with my help, please Rate me. That is how I get credit for my work. I hope I have provided you with Excellent Service.
Well, you really need the scanner for direction. Do you have one that can monitor the fuel trim readings?
Ok.. Well it will be easier for me to help you then.
