wich engine do you have?
Right from the 1991 Explorer , the 4.0 L OHV engine was EDIS ( electronic distributorless ignition system ) using a coil pack instead of a distributor
10 degrees BTDC ( unless engine compartment decal shows different )
Were are the timing marks on a 1991 acura legend
Timing chains, no belt.
on my 1991 5.7 L mercruiser blue water the timing should be 8 degrees before top dead center.
I believe that has the DIS, distributerless ignition system, if so there is no timing adjustment. The timing is controlled by the ignition module, crankshaft sensor and the ECM (engine computer). Try having some run a test using and OSB tester. Sometimes if the sensor is going bad it will show.
If you mean ignition timing it will be 10 degrees BTC.
10 degrees advance
Yes , the 3.0 liter V6 engine in a 1991 Nissan Maxima has a timing BELT ( P.S. - it is also an interference engine )
I think what you are looking at is a distributorless ignition system. All engine controls are routed through the ecm, or engine control module and timing is changed automatically as needed for emmissions and performance.
The 4.3 litre V6 engine in a 1991 Chevrolet S-10 has a timing CHAIN
1991 mercury cougar i need to know the egnition timing engine is a 3.8 v6.
The 3.8 liter V6 engine in a 1991 Mercury Cougar has a timing CHAIN
If the timing belt breaks on any engine the damage to the engine is usually very bad.
Special procedures required Follow instruction on hood label or service manual
ECM means Engine Control Module. It is the car's computer and controls ignition, spark, timing, emissions etc. A vital part of the car.
The Ignition Control Module is on the top left hand side of the engine under the Ignition Coils.
it is an interference engine, so get you timing belt changed
Probably computer controlled and not adjustable
The 1991 Ford Probe spark ignition module can be found on the firewall in the engine compartment. The ignition module will be on the drivers side of the firewall.
No , the 5.0 liter High Output V8 engine in a 1991 Ford Mustang GT has a timing CHAIN
