Skip compression test, the results will be misleading. replace the head gasket on this series of Sentra. The first symptoms are that it take slightly longer to starting when it has been shut off warm for about an hour
Computer box problemleads to?
Is this " mechanic" not diagnosing and scanning the issue ? Sounds like a new parts fitter.
On those Nissan 4 cylinders with higher mileage they have been known to have an issue sounding like you explaining caused by the timing chain getting stretched a little too much causing an issue with your timing. Hence misfiring. Now I must say that there are other things that can cause misfiring too. For instance fuel. Have him hook up a timing light and see if it is firing after top dead center. If yes .. could be a stretched timing chain. Hope this helps

Good luck

Replaced sterring colum now it wont start
S (Nissan Vehicle Immobilizer System-NATS) has the following immobilizer functions: Since only NVIS (NATS) ignition keys, whose ID nos. have been registered into the ECM and IMMU of NVIS (NATS), allow the engine to run, operation of a stolen vehicle without a NVIS (NATS) registered key is prevented by NVIS (NATS). That is to say, NVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS (NATS). All of the originally supplied ignition key IDs have been NVIS (NATS) registered. If requested by the vehicle owner, a maximum of five key IDs can be registered into the NVIS (NATS) components. The security indicator lamp blinks when the ignition switch is in "OFF" or "ACC" position. Therefore, NVIS (NATS) warns outsiders that the vehicle is equipped with the system. When NVIS (NATS) detects trouble, the security indicator lamp lights up while ignition key is in the "ON" position. NVIS (NATS) trouble diagnoses, system initialization and additional registration for other NVIS (NATS) ignition key IDs must be carried out using CONSULT-II hardware and CONSULT-II NVIS (NATS) software. Regarding the procedures for NVIS (NATS) initialization and NVIS (NATS) ignition key ID registration, refer to CONSULT-II OPERATION MANUAL IVIS/NVIS. When servicing a malfunction of the NVIS (indicated by lighting up of Security Indicator Lamp) or registering another NVIS ignition key ID no., it is necessary to re-register original key identification. Therefore, be sure to receive ALL KEYS from vehicle owner. System Composition NIEL0174 The immobilizer function of the NVIS (NATS) consists of the following: NVIS (NATS) ignition key NVIS (NATS) immobilizer control unit (IMMU) located in the ignition key cylinder ECM Security indicator lamp.
