First and foremost, check your CAS timing. Wouldnt hurt to put the engine to TDC, restab the CAS, then shoot it with a timing gun to make sure its lining up with the 4th mark from the left on the main pulley. Also, since you said it runs crappier when its warmed up, wouldnt hurt to replace the ECU water temp sensor (2 pin water temp sensor) on it.
