SOURCE: throttle position sensor
did your car have (ETS) electronic throttle control system
the TPSis a part of this system
but you can test it by using diagnoses scan tool to check the TPS value when press or depress the accelerator pad.
so you can tell us the NO. of DTC for example(P0122)

Let me get this straight, you took your Nissan to the NISSAN dealer (who has extensive data and resources) and they said you needed an engine due to the timing had jumped and you declined due to the $6500.00 price. So you took it to the independent guy (local mechanic) that is guessing and throwing parts at it and most likely making it worse because you only needed an ECM that the dealer said was ok, 2 cam sensors and 3 coils (but hey its cheaper than an engine). So now you have a used ECM that doesn't belong in the vehicle that you most likely didn't need and are awaiting the correct one from Nissan. You now have or will have 3 working ECMs, 4 good cam sensors and nine good coils in a van that will still not run. Ok and now you think that the independent guy (local mechanic) doesn't know what he's doing and you want to know if anybody knows a good mechanic. Whatever gave you that impression?? I know now what the problem is.....it's you. You tried to save money but it didn't work. Hopefully you didn't do any further damage but who knows. Get your money back from the local mechanic and take your van to the dealer to get the engine you need before someone else takes you for a ride or damages your vehicle further.

this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.

You will need a new catalytic convertor assembly. Yours is below treshold efficiency in other words its "no good".If you have it replaced, ask the garage/dealer to give you the old one back. Its worth some cash if its full. It doesn't matter thet it failed. They are going after the mesh inside of it and that is worth some $$$$. May not be much , but better than nothing.

the computer may need to be reflashed. if it is running then it is not a bad sensor. either of those being bad would cause it not to run.
