Wherever the engine stops there will be at least a couple of valves held open and overnight the force of the valve springs can force the oil from some of the hydraulic tappets (if fitted). Some engine designs can take as much as 20 miles to cease tapping... Some timing chain tensioners are oil damped. If noise disappears when you top up the engine oil the clear solution is to top up more often - the engine oil level should never be allowed to fall more than 1 litre below the maximum level and it should never be overfilled. Locating and curing the cause of excess oil consumption can be expensive and complex and the process involves a certain amount of guessing and eliminating so sometimes it is better, quicker and cheaper just to have the engine overhauled. The general rule is it isn't economic to repair excess oil consumption unless it exceeds 750 miles per litre of mixed driving that doesn't include any sustained high speeds unless there is smoke when the engine must have attention or be scrapped. Before testing the oil consumption the engine breather should be checked and the oil topped up accurately. If there are no visible crankcase emissions caused by excess piston ring/bore wear, the most likely cause of excess oil consumption is the valve stem oil seals - unless the engine is so gunged inside the oil being pumped to the top of the engine can't drain back fast enough...

chips don't go missing Find an accredited service center that can properly diagnose the fault

replace the IAC sensor , then use a scanner to reset the ECM

its inbetween the air filter and the throttle body with wires hooked up to it

Sounds like a bad throw out bearing-when you did the clutch (and presumably the pressure plate) did you replace it too?

Random multiple cylinder misfire indicates a weak spark or at least that is the most common cause - most misfires are ignition related and as that is the easiest to service and test it is best to eliminate the possibility first. The coil resistance should be checked against specifications and if found ok test the spark power is sufficient. If the spark is insufficient it is possible it is weak because the ECU is not working correctly or because the voltage supply to the coils is too low. Check the spark plugs for fouling and wear, especially baked on town running deposits. Clear the code(s) before every test.

-Here how to do some sample test: -Check in fuse box. Only one relay for both light or two relays ? -If two the swap the relay to find out it's bad relay or not. -But if there is only one then do the following: -Remove the bulb. Turn it on and check to see any power there or not. by connecting a millimeter to both lines. It not power then connect one line at a time. - 1 lead to the line and 1 lead to the metal frame . If power present then it's bad ground. But if it still have no power at all then Possibly the power line is been cut some where . Good luck Mai
