2003 V6, never missed a beat but now got s prob.
Basically it started with a misfire and engine light intermittently comming on. Got a diagnostic check done, code was a misfire on cylinder no 3.
Changed plug and coil pack but still running lumpy and tickover 'hunts' very slightly.
Engine light on perminantly until medium / hard accelaration then it flashes.
Also exhaust seems to be getting getting hot / not quite a burning smell but well...a hot smell lol .
No coolant loss / no signs of head gasket gone. Dipstick spotless. No back pressure. Engine runs at correct temp. Heater / thermostat etc all working correctly.
Does the ecu shut down the cylinder with the misfire and keep it shut off until the fault has been cleared via diagnostics.
Does that also mean unburnt fuel finding its way into the exhaust, giving me the hot exhaust symptom ?
If its not the plugs / coil, what else could it be ?
Appreciate any help. Thanks everyone.
