today i pulled a few leads off found that it seems to be only running on 4 cylnders no spark out of 6 and 8 what would make it drop spark on those 2 but i think its only running on 4 cylnders?i once read a story about a crank angle sensor doing a similar thing...im leaning towards that or the computer since the distributor cap n button n leads r new im pritty sure 5 and 7 are the same but i did it at night and burnt the s@#t out of myself removing a lead so i didnt test them properly i just cracked it and went inside...please help...any advice would be gladly appreciated...does anyone know how much it is for a crank angle sensor?and the price of another computer im just worried about changing the computer because it has a custom chip

If you have a distributer you don't have a CAS.....the problem you describe seems to be to do with the ignition module and/or the distributer. Try a search on this forum.

thanks hako will try suss that out dont know much about the whole setup really the newer cars have me lost...so i guess my best bet is to change the distributor..thanks for the link much appreciated... my problem seems to be alot diffrent to theres tho why would only a couple of cylnders stop firing all the time now they just have no spark ever without a doubt...ps thanks for replying to my post your a champion thumbs up
