you don't computer controlled engines have idle speed set by the computer
For a VW 1303 distributor converted to Pertronix electronic ignition, the timing mark should generally be set at the factory specification, which is typically around 7.5 degrees BTDC (before top dead center) at idle. However, it's essential to consult the specific Pertronix instructions for your model, as some setups may require slight adjustments depending on the engine and ignition system. Always ensure that the engine is at the correct idle speed when setting the timing.
Idle speed control
Even so eclipse uses distributor based ignition system, I'm not sure that you can adjust timing. The timing you can adjust is idle timing. But it basically never needs to be adjusted.
A 2002 S10 may surge at idle speed due to several potential issues, including a vacuum leak, which can disrupt the air-fuel mixture, or a faulty idle air control (IAC) valve that fails to regulate the engine's idle speed properly. Dirty fuel injectors or a clogged air filter can also contribute to inconsistent idle. Additionally, issues with the ignition system, such as worn spark plugs or ignition coils, might cause irregular engine performance. It's advisable to perform a thorough diagnostic check to pinpoint the exact cause.
On a 1995 Nissan Pickup, 2.4 liter engine, the crack angle sensor is located on the distributor under the distributor cap. It is regarded as the right hand to the ECCS control unit, as it is the basic signal sensor for the entire ECCS system. It monitors the engine speed, piston position and it sends signals to the ECCS control unit for control of the fuel injection, ignition timing, idle speed, fuel pump operation and the EGR functions.
Due to the electronic fuel injection system in the 1997 Dodge Neon it is not possible to lower the idle speed. The engine control system computer adjusts the speed automatically.
1. Engine Idle speed set too low? 2. One or more cylinders misfiring at low idle? (Spark plugs, plug wires, distributor cap or distributor rotor would be the common culprits.)
idle speed too low? loosen bolt at bottom of distributor cap and turn the dist. cap slightly while the engine is running to change idle speed. then tighten bolt when you find a good speed.
A distributor going out typically does not make a popping or sizzling sound. Instead, you may experience symptoms like difficulty starting the engine, misfiring, stalling, or a rough idle. If you hear popping or sizzling sounds, it could indicate a different issue such as a problem with the exhaust system or ignition components.
your ignition coils and distributor...they should be blocks...u can get a three pack of blocks at your local auto parts stire
Contact breaker point gap 0.45-0.55 mm Distributor dwell angle .49-55 deg Ignition timing at idle speed 7 deg btdc in neutral That's the same for A14 & A15
# Idle speed incorrect # Fuel filter clogged and/or water and impurities in fuel system # Damaged or wet distributor cap and wires # Emissions system components faulty # Faulty or incorrectly gapped spark plugs my 2002 mountaineer did the same thing and it was a crack vaccum line.
