PREVENTITIVE MEASURES

Change spark plugs to 1 range cooler for extreme driving and hot climates.

Supercharger oil must be replaced at 2500 miles from install and then every 7500 miles. You can purchase the oil

from www.vortechengineering.com

Change engine coolant temp senor whilst installing the supercharger kit (often a cause of fuelling issues on cars of

any age).

When disconnecting OEM electrical connectors, label them to avoid potential confusion when re-assembling.

TROUBLE SHOOTING & MAINTENANCE TIPS AFTER INSTALLING SUPERCHARGER KITS

Injector wiring on older cars can be brittle –check for proper connection

Contact pins inside injector electrical connectors can bend back if the connector is ever mis-fitted and lead to

intermittent connection and cylinder misfire.

Loose crankcase vent tube is considered a vacuum leak and will cause poor fuel trimming.

Loose crankcase vent tube to oil separator is a common cause of vacuum leak.

Vacuum leak at hoses around silicon couplers may not be visible but is a simple mistake.

Weak OEM crankcase vent tube (Melts with age) will cause vacuum leak.

Clean crankcase vent tube and inside of supercharger intake duct every 20K miles and inspect for leaks and kinks

and possibly replace.

SYMPTOMS AND POSSIBLE CAUSES

Hunting idle – major vacuum leak – check silicon couplers especially on throttle body and idle stabilizer.

Smell of fuel – incorrectly fitted fuel injectors.

Misfiring – bad electrical connections to fuel injectors or spark plugs

Overheating – air lock in coolant system

Very erratic idle – verify Mass Air Flow sensor may be fitted oriented in incorrect direction

MAF signal CEL – check wiring harness extension and electrical continuity in extension harness
