I just did a zc swap, and dx to zc engine harness conversion. AFter driving for about a minute or two, i get a rev limiter @ 2500rpm and codes 7, 14. I switched out 2 tps sensors. And the IACV valve looks fine. Anybody got a clue as to what is wrong?
Thanks.

Any help is greatly appreciated.

 

With the TPS, Put the key in the On/Run position. grab a voltmeter and test the Red/blue wire. It should be .45 volts at idle and 4.5 volts at WOT. If not try adjusting it, if that does not work then you will have to replace it.


For the IACV, take it off the car and take some carb clean and clean it out.


See if that works.

 

I just swapped out my ECU with a chipped one, and when I put my stock one back in it threw 7 and 14 also... Tried resetting it, nothing, took the thing off the back of the intake manifold, cleaned it out... Same thing, replaced TPS... Still nothing... I don't get it.
