Ok so a little while back my supra was running pretty good minus the fact that it needed a tune. well then all of a sudden it wasnt get spark so i troubleshooted and found that the CPS was bad. so i replaced it. well now when i go to start it sometimes it fires up other times it doesnt but if it does fire up it stalls itself out right away and smells like its running very very rich. do you think the problem lies in a timing condition from installing the CPS? any help would be great. thanks
