I just got an engine swap done on my 92 coupe and its been running great untill today it started to not want to start. When I go to start it it turns over a couple of times before it starts, today I was at work and I just got done letin it cool down before I shut her off and then I had to turn around and leave like 5 min later but it didnt want to start it sat around 3 hours I cam back and it finally started. Then when I get home I was letting it cool down while i unloaded my gear and realized my idle was spike it would jump up to about 2000 and then go down to about 700rpm. \

ANybody kno what the problem could be im thinkin fuels pump are injectours

SR? KA? Check plugs for foulness and regap them. Air Filter? Pretty wide symptoms you gave us. Sounds to me like you want to some magic screw to tighten and all will be well. Sorry. These are 240's. Go pop your hood and start looking too. May be time for a full tuneup including quality wires. And if you did any work to your car recently double check all that.
