Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
hi are there any codes in the system or is the check engine light on?
if the engine light is flashing that signifies a catalyst damaging misfire. it sounds to me like you are having a misfire when the vehicle warms up.
do you have easy access to al the spark plug wires?
then my idea i wouldnt recommend.... is the crank sensor located behind the timing cover down by the crank pulley?
if you have access to that i would try changing that first to see if it goes away.
i am sorry yes that is what i ment i would try replacing the sensor first.
ok please let me know what happens and if you may give me a rating.
have you tested them while the vehicle is messing up. im thinking that the engine heat may be disrupting the signal.
although if they still test out okay i would check your ignition system. the three coils infront can be unplugged one at a time while the engine is running rough to isolate the issue to what cylinder. although one coil runs two cylinders i dont recommend unplugging the wires one by one as you will most likely shock yourself and it does not feel good.
other than the ignition system it could be a fuel issue but is unlikely.
you said you rechecked your timing alignment and so i am not looking at that for now. and considering the symptoms i dont believe that could be an issue.
