Its most likely one of two possible causes. It could be the IPDM box's ECU relay, that will cause a number of different problems with idling and rev limiting. Swap the ECU relay with the fog light relay first, since it won't cost anything. The other possible cause would be the fuel pump. Titan's have they're fuel filter built into their pump. The pump is cooled with the fuel in the tank, so if it was a slow building issue or if you run your truck low on fuel often then this could be your problem. If it happened sporadically and out of nowhere then I would swap relays (ECU with fog light relay).
Normally I look at timing as this issue but being that new it is unlikely. Check the MAF sensor and PCV valve as well as the Vacuum system for leaks. After that it becomes an issue of the valves or compression. Do a compression check to see if your compression is good and check if you have a compression leak. If you have any issues in your compression your going to have issues building RPM. It is possible the issue could be a Cam Position sensor or Crank Position sensor but you would have a check engine light if either of those conditions existed.
Hello, number of things. Have you run a diagnostic test on your truck? It could
be throttle sensor, air flow sensor, electronic spark advance, extremely dirty
fuel filter, dirty air filter. fuel pump,
fuel ratio sensor, and they are many other components that can go wrong.
