hey everyone so this is really stupid but bare with me so i baught a d17a2 head and put it on my vp and it worked fine untill the ecu shorted because of the wireing to my vafc, so i took it in to get it fixed and the guy gets an ex ecu since we have to reflash the keys anyways, it is in and it starts and runs fine, still has the old harness and the vafc but it revs up to 3800 rpms just fine then nothing, sounds like the rev limiter, i dont know what it is. could it be the vtec oil switch, or something since it is not getting a reading to the ecu, please help i am just stuck with a car that does not run.

 

You're in limp mode. Get the codes pulled at AutoZone, and see what's reading improperly.

 

the code that is reading is the vtm signal, because i have an ex ecu because of the vtec head and a dx-lx harness, so it is not connected could this be the problem, if i connect the vtm to the ecu will it return to normal.
