i searched through the forums and did mostly everything that everyone told me to do ... car has new wires plugs cap rotor it will not rev past 3200rpm i need some straight answers of what it could be its a first gen JDM b16 motor sat around for a while it idles a little high and all the wiring is correct im getting a code 4 and 6 im changing the coolant sensor and will come abck and update after that any help is appreciated.........

 

It sounds like a distributor issue to me. I forget which sensor though.. it's not the TDC sensor, but one of the other 2....

Maybe someone else can say...

 

4 = ckp sensor, check your wiring. thats whats stoping it from reving higher

if the wiring isnt correct at the dizzy it wont start no wires are crossed because if they were then it would just crank cause the PCM wont recieve any signal its starting just not revving past 3200 and i have pretty much ruled out the PCM and a tune up and the wiring although this was a DPFI to MPFI conversion harness and i back tracked and it all loks good unless i have to repin anything at the tower and or need to cut a wire at teh PCM
