General information
| System type | With sequential fuel injection and electronic control |
| Recommended fuel (minimum octane) | 95 RON |
| Idle speed: | |
| 4-cylinder engines: | |
| Regulated - nominal (±50 rpm): | |
| Models with non-automatic transmission | 880 rpm* |
| Models with automatic transmission | 710 rpm* |
| Unregulated - basic (only release models up to 07.1996 | 1500 rpm* |
| V-shaped 6-cylinder engines: | |
| Regulated - nominal (±50 rpm | 725 rpm* |
| The content of carbon monoxide in exhaust gases: | |
| 4-cylinder engines, no more | 0.5%* |
| V-shaped 6-cylinder engines, no more | 0.5%* |
* Parameters for reference only (not regulated)
Operation of the rev limiter
| Disabling fuel injectors: | |
| automatic transmission (pregnant "N") | 4100 rpm |
| automatic transmission (in other positions) | 6800 rpm (approximately) |
| Non-automatic transmission | 6800...7100 rpm |
Fuel pressure
| Adjustable fuel pressure (at idle): | |
| pressure regulator (vacuum hose connected | 2.1±0.2 bar |
| pressure regulator (vacuum hose disconnected | 2.7±0.2 bar |
Note: After the ignition has been switched off, the pressure in the system must be maintained at 1.8 bar for at least 5 minutes. On a hot engine, during this test, the pressure may increase, but not more than up to 2.7 bar. pressure regulator (after joining) should not allow higher pressure.
