Ok like the title said I have a D16Z6 that wont rev past 3000 and the idle is a little rough. I thought it was my TPS sensor (damaged during swap) I replaced it but no change anyone have any Ideas. I search on here and saw some one mention the distributor does any one know how I could test this.

 

sounds like an ecu problem or possible vtec issue.

what kind of mods do you have on this motor?

 

does the speedometer jump at all? If so, it could be Vehicle Speed Sensor. my buddies speedo jumped and he could not rev past a point, so he just replaced his VSS and it corrected the problem.

 

make sure the spark plug wires are in the right order... also disconnect the battery and hold the negative and positive cabels together for 2 mins and then reconnect it and start the car and rev it up.... this will reset the ecu

 

A buddy of mine has another ECU going to swap that tomarrow yes the speedo does jump around I just picked up a VSS sensor at autozone going to install it tomarrow

To answer your question the motor is clean no mods yet.

If any one can think of any thing else I would appreciate it. I will let you all know if any of this helps.

 

Check timing. On the D16Z6 I think it should be 16 degrees BTDC.

 

happened to me when i did my swap. wouldn't go past 3k but i had a code for my TDC sensor. it was shot so i replaced the distributor

 

Ok not the VSS sensor replaced no help also disconected the cat and no help there either.

 

Ok thanks for the help problem solved it tured out to be the cap and roter the set screw had come out and the roter had jamed at an angle and was not making good contact and on top of that oil had gotten inside and was mucking the place up.

 

new cap and rotor it is then. happend to me before aswel. try getting some thread locker for that screw so you wont have to worry about that problem again anytime soon
