car running poorly

[jcroziercbad]

I have a 1992 SVX and just went through a major problem after the car overheated from a broken water line, which has been fixed. Now I'm having a problem with the car running very poorly at idle, which it doesn't even idle at the normal RPM as it did before the water line problem. Before all the problems started it would idle at 1500 rpm, but now it seems to jump between 1000 and 1500 rpm. We checked the codes right after it had over heated but before we fixed the problem and it was telling us that there was something wrong with the crankshaft angle sensor and the camshaft angle sensor (can't remember which camshaft sesnor though). After the whole overheating issue started the car wasn't able to start, it would turn over just not start. We are going to check the codes again but at this point I couldn't tell you what they are.
