The possibilities are endless. do a compression check on the cylinders and see if your dropping a cylinder. If so this could be a valve sticking, bad head gasket, cracked cylinder wall (Where I would really start looking). Your symptom, by your description, starts after the vehicle has warmed up which tells me it is something that is small that gets bigger as it heats up.

My car has a timing chain, when I start my car in the morning its very noisy then it quite down a bit,


noisy on start up is hydraulic lifter problem as they are loose until the oil pressure builds up. the adjustment is taken up and the noise goes
it mat have some noise from the chain until the oil pressure builds up as it has a hydraulic chain tensioner
you list it as a 2016 model and the only suggestion I could make is to go up a grade in oil viscosity
AS it is new the oil is probably 15w where I would use a 20 w 40 oil
run your engine against other new engines and see if the engine noise is louder ( use a noise meter ) and make the dealer do something as nothing gets quieter as it wears out --just louder

Fuelpump making bad noise took inline filter off it stopped making noise and pumped good replaced filter it it still want run and pump is making noise


Noisy pumps are going bad. It probally pumps but it can't make enough pressure and flow under pressure. Fuel pumps are checked with fuel pressure gauge for pressure and checked for flow rate to manufactures specifications.

Ford sport trac, 4.0 dry start , and then continue ticking sound ,ive been told timimg chain


how many miles on the vehicle? does the noise quieten down when the engine RPMs come up? timing chain is very likely if you have over 150,000 miles. lifter noise is a more common problem. the lifters will tend to quieten down as the RPMs come up due to more oil pressure.

Symtoms of a bad timimg chain/belt...but ran real


Problem is not solved but I did change the fuel filter, coil pack,ICM and have proper fuel pressure to the motor. Car starts but dies right away. I cant seem to find out if the fob on the key ring has something to do with stopping the motor. This fob says Radio Key by Secure Key with a number 35077 stamped on this thing.. Still trying to find out what this is and does it effect the cars ability to run

Car feels slugish when going up-hill, slight vibration, level and downhill runs ok, from start shifts through gears fine, just feels odd at times


problems you described would suggest you need to replace the spark plugs, a bad one tends to fail under loads like going up hill. the other thing you could try is to get a better fuel grade, that would correct pinging noises uphill. and throw in some fuel injector cleaner every 2000km, it makes a happy running engine

1993 Nissan D21 4cy 4WD STILL won't start


I have owned 6 nissan ka24e engines and I have had a similar problem. Since it was running strong, compression won't be your issue. One of mine had under 140 on all cylinders and it ran fine. Second, did you check the valve timing. These engines are known for faulty timing chain tensioners and guides. Tensioners are oil pressure controlled. Might just want to take a look at the slack in the chain. Also make sure the timing chain marks on both gears are in correct position. If all this is in order, you may think I am crazy.... However, after replacing the engine in my 1990 240sx, same engine, it pulled very hard for over 3 months. Then one night, I was pushing it pretty hard, it just died. I replaced coil and then was broke. After hours of looking it over, I noticed one of my ground wires on the intake was loose. Even though the spark plugs were firing and fuel pressure was good, it would not start again until I replaced the ground. The ground was only an 18awg wire, but apparently it is a ground for the ecu. I would suggest checking all of your grounds for the engine, 2 coming out of main harness and bolting to the intake and 1 going from the head to the firewall. Please let me know if this fixes your problem. I consider myself a nissan expert with over 13 years experience. 10 of those years were with this particular engine. My email is t240guy@yahoo.com. Please let me know if you have any other questions.
