i just bought a 93 ssei with engine in pieces, i put the heads ,intake and supercharger on the car, while trying to start found a broken gas line on the body of car, fixed it so it holds pressure, car will start holding throttle wide open, sounds like its running on 3or 4 cylinders, codes are 17, 18, and 23.....let the game begin

17 cam position sensor fault
18 crank or cam sensor error
23 intake air temp sensor out of range, low

Sounds to me like you don't have something plugged in right. Start by going over the wiring harness.

thanks dan, i can tell you everything is plugged in correctly, but i cant say there isnt a broken wire in the harness some where i cant see, just for fun i did replace replace cam sensor....no change, car only runs at wide open throttle but sounds like only 3 are working.....

I would start testing the wiring harness.
