So i just swaped the old se engine and put a used one, i got it running but it did not pull like my old one, i did not have it timed and still dont,
i tried to time it but found out that both of the leading plugs are not firing, i did the dlidfis mod and was working fine on the old motor, i checked it out today and is getting the 12 volts all the way up to the coils, and tried to remove the plate where they are on and i woul see it spark when i was taking it off and checked if it sparked when i touched it, but for the moment when it sparks that it touches the shock stud where its mounted the plug fired, i tried grounding it but it does not work so i was wondering if any body that did this mod had any problems like this,
i tried going back to the stock ignition but now that does not even work!
Ohh and the car runs and iddles rough but iddles and i drive it and it feels like normal when driving and it even pull alitle but not like my other motor, and its running only on the trailing.. so can someone tell me if this is normal??
