Hi all recently bought a 1989 19E with the 2.6L in it, the car ran fine before, had and exhaust leak on the back manifold so I fixed it. Now the car will turn over and fire but not stay running. Does anyone have any ideas as to why the car won't run now? I had to pry on the manifold a bit to get it to come loose but it seems to have sealed up just fine. Might have switched plug wires around would this cause it not to run properly? And anyother ideas? thanks guys starting to get annoyed

wife needs this car by saturday.
