COMMENT

｠

In cases such as the above, the ignition system, air/
fuel mixture or compression pressure may be faulty.
In addition, if the engine suddenly stalls, the cause
may also be a connector damage.

TROUBLESHOOTING HINTS (The most likely
causes for this case:)

｠

Malfunction of the fuel pump system.

｠

Malfunction of the ignition system.

｠

Poor compression

｠

Malfunction of the EGR system

｠

Improper operation of the PCV valve.

｠

Vacuum leak.

｠

Malfunction of the ECM.
