Having problems with your 1993 Saturn SC2 ?

I have a 95 saturn just had another engine put in , they say 72000 miles. we took the car back because of a oil leak and it came out missing and chugging. I drove the car cold it seemed ok then the engine warmed up and its running bad again. no light is on the dash. the guy that put the engine in and worked on the leak says its not the engine help It just cost me 1400. I wish I knew more about cars

Do you know where the oil is leaking. I had a bad oil leak coming from the valve cover. Because the plugs go into the head the way they do. there are seals around the holes that house the plugs. pull your plugs and see if the well is filled with oil. If so this could be the problem. Also check to see if your low on oil when it starts the chugging and missing.. It could be that the leak is so bad your not getting enough compression. Also just check your plugs, I don't know how many times I have fixed a car by just changing the plugs. You would be surprised at how many of these guys that swap an engine wont even put in new plugs or if they do won't gap them. Finally check your air filter, this is another thing that will greatly affect the perfomance on your saturn. My wife came to e and said ours was bogging down really bad. I went over everything and finaly found the problem was just a bad filter.
First I would hope the person that did the engine swap will stand behind their work and at least demonstrate to you it is not something they did incorrectly with the swap. Oil leaks on used motors is a risk, if they broke any seals while doing the swap then they should repair it. The suggestion to run the B12 is okay but not helpful to your problem. Now most parts houses will connect their scan tool for free to the car and tel you what if any error codes are set, then based on that your used engine could have come with a deffective part. The results of the scan tool will dictate the next step in troubleshooting and resolution. Find out what parts were not swapped from the old engine, one of them could be suspect. If its not the engine the "mechanic" should at least give you an estimate to complete the repairs.
