If petrol, suspect coil pack/ecu.
It has a miss fire.One or more cylinders are not firing. Check spark and compression for each cylinder.Check ignition timing and hoses for a vacuum leak.
P0303, number 3 cylinder is miss-firing. You could drive it but depending on the reason why it is miss-firing, it may damage the catalytic converter.
Yes.
you should take it to a car tech or some one that knows how to set the timing if that does not work you should have your timing belt replaced.
Usually miss fires are caused by faulty spark plugs and ignition wires.
Well...the misfire on 1 and 3 would explain the rough idle. The misfire could be from worn plugs, wires, bad coil, or bad injectors.
#1 cyl checked with falt metter
One or more cylinders not producing power for lack of spark, fuel or compression.
depending on the year it could be the coil pack is bad. mine was cracked really bad and occasionally would miss and all the sudden while driving down the road one day it just stopped working and i had to ''milk'' it home because it had NO power. i replaced that and was driving with no more miss to the engine
what do u mean not running right? is it miss firing, etc?
I put a computer on it and the onely code that is coming up is all 6 cylinders are miss fireing.
Poor mileage, loss of power, miss on one or more cylinders.
