Sounds good, if it takes care of the speedo and tach I guess you will be going to another forum. There are 135 amp ones that may help you blow out your back windows lol.

Hey, did your stumble get cleared up? My friend has a twin cam in his cavalier, and he has some of the same problem. it sounds like an injector issue, you may want to get the injectors and fuel rail cleaned out, sediment likes to gather down by #4 injector.

ya my stumble comes and goes. thats a good idea tho, b/c when i was checking it out, i popped out my plugs and they all seemed good, although #4 was a little dirtyer than the rest. my injectors all have good resistance but it could be that # 4 just keeps getting sediment in it, which causes the stumble. what do you figure is the best way to clean out the rail? just pop it off and blow it out and maybe a bit of brake cleaner? ive never done that before and i havent really ever thought of it.
