I would contact the people you got the custom cas and see if any other people had the same problem.

Try reversing the order of your spark plugs.

Hi i already did... both ways
Here is the deal i have a 1997 GSX with RRE cas plug running EPROM ECU WITH dsmchips chip with the cas inversion and random misfire delete...

So the misfire should´t exist.... and i know the chip works good because i use it on my friend 2G talon same chip on he´s car and works perfect...
We both have rc 750cc can my injectors produce the random misfire?

You need to provide more information about the car and about the chip. What is the chip programmed to do? Does it simply adjust fuel compensation for your injectors? Does it invert the CAS signal?

What mods does your car have and was it running before?

Do you have any logging mechanism? Gauges? What are your AFRs? Have you verified your fuel pressure and spark? Is our compression good? Have you done a leakdown test?
