Well here is the situation. A month ago I installed a Jacobs ignition. A week after I put it in the car started running like poop. It had jerky acceleration and was just slow and not running right. I thought it was a fuel system problem so I changed my fuel filter and fuel pump which were old anyways. Nope. I have new spark plugs too. The car doesn't bog as much after I changed the fuel pump but it is still there. I'm not sure what could be the problem. My brother doesn't think that its the ignition booster but I have my doubts. The engine is around three years old and was professionaly installed. All my vacume hoses are connected. I am wondering if anyone might have any ideas for what is wrong. Thanks.

look in the FSM there are resistance values for the coils that you can test with a DVOM. check all the connections closely, i think it gets a connection from the CAS, make sure that one is in very good condition as the CAS is very sensitive. (i THINK it gets a connection from the CAS installing an ign. box is one thing i havent tried yet, will be doing 2 MSD's soon on the T2 tho)

no the jacobs box does not connect to the cas, it only is supost to connect to the leading coil/ignitor.
now after your wiring check do a compression check to the motor. kinda sounds like your motor went south on ya.

allright. I did a compression check. Front rotar, 115 all three, rear rotar, 120 all three. The motor is good. I checked the readings on the coils and they read within parameters. Is there anyway to check my fuel injectors. I put injector cleaner in a couple of weeks ago and that didn't help. Any other thoughts. Thanks.

well that was the best thing to do. The jacobs was the cause of it all. I didn't remove it sooner because I ruled it out because it was working for a week before the problem started. The unit I bought was used. The car runs good again. Now on to see if I can get a new one somehow via trade in or what not. Thanks for you help guys.
