The car is an 88 2.5 base model that I last worked on about 18 months ago because I had a car accident. At the time I replaced the fuel pump and lines as they where weeping. I replaced the ignition unit and coils, brake pads, Battery cables and other maintenance items. The tach was always acting funny since I bought the car so i purchased a new tach board but that didn't solve the issue. Now that I have recovered enough to work on and even drive the car the tach started to work interminably and now stopped working all together. Does the 2.5 have a tech filter live the v6? I have a newer dash that i put in to check if the tach it self was bad and that didn't help.

No tach filter on the 87-88 L4 with the DIS ignition.

check the connection on the distributor I believe it's different from the v6 I understand better and mine was hardwired its nost likely a dying module or a broken wire or messed up connector
