I have a 94 eagle summit that runs real rough. I've replace the computer in the vehicle but it still runs rough and sometimes won't run at all. Someone told me it could be the crank position sensor but I don't think there is such a thing on the 94. Can anyone help with this?

Check for any codes stored in the computer by doing the following:

Make sure the ignition is off. Find the computer connector underneath the dash by the fuse box. Consider the row with the most holes to be the "top." Take a piece of wire and insert one end into the 1st hole and the other end into the 4th hole, with the 1st hole being the top left and the 4th being 3 spaces to the right. Turn the ignition to on and count the number of times that the check engine light flashes; there will be a number of long flashes and a number of short which will tell you what code is stored in the computer(example: 3 long flashes and 2 short ones would be a code 32).

Post the code here after you retrieve it and we'll go from there!
