No, it does not fit like an old style HT lead, but there should be a spring in the coil to make a good connection between the coil and plug.

why my raditor is hot when go slow?but when go fast the temperature is go down?can u help me what the prroblem is?

[AskTheMechanicCoUk]

If it overheats when in traffic or slow speeds, the electric cooling fan may not be working, the fan is not needed when driving faster as the air flow cools the radiator.

[AskTheMechanicCoUk]

No need to disconect the battery, just remove the keys from the ignition

HEY IF IM CHANGING MY IGNITION COILS SHOULD I ALSO REPLACE THE COIL CONTROL MODULE? (THIS IS ON A 3.8L V-6)

[AskTheMechanicCoUk]

Normally if the coil comes without the module it should be ok to replace just the coils

@AskTheMechanicCoUk After getting a tune up from an amatuer mechanic my car started shaking like that at startup. I feel it was a bad plug or bad innition coil and my car is running hot. I changed the water pump and the thermostat and it still run hot and it has a hesitation when I accelerate when the car is cold.

hi I have a Renault megane 1.4 16v 2003 my revs are going up to 3000 when am rolling in nutral but when I stop there at 1100 and jump to 2000 I've changed throttle body cleaned electrics what do u think problem could be thanks

It is a wasted spark system and only has one coil per cylinder.

The main reason for wasted spark is to simplify the ignition system, if we fire 1&4 and 2&3 together, we don’t need to know which piston is on compression stroke, only that it is at the top of its stroke, so we can get all the information from the crankshaft position sensor and don’t need a camshaft sensor.

The plug is fired on compression and exhaust (wasted spark) stroke.

Citroen 2CV used wasted spark, no rotor arm or dist cap.

Is this one of those spark systems where there is spark with every crank revolution? Thus spark wasted every second cycle, but two cylinders per coil? If not, why is 1 linked with 4, etc?
