Car has 77500 on clock
How do I fix that

Dear customer, have you done maintenance to the throttle body system recently? incluiding throttle body and the admission.
According with the mileage its neccesary to do it and change the air filter.

Only had car about 3months haven’t done anything with the car it had service about 1000 miles ago and had a throttle actuator also about 1000 miles ago but only 1 actuator

Dear customer, before change any part of the throttle body. You should do a maintenance to the throttle body system with special cleaners, desassembling the whole body to clean everything and clean the electric parts with and special cleaner for electrical parts and then assemble it again, then with and automotive scanner tool the error codes must be deleted. And it would sort out the problem. I do not think that it coulb be a major problem with the actuator since my position because i am not with the vehicle to give a better diagnosis.
if the problem persist then the problem is in the throttle boy and some parts must be changed but i do not think this is your case.
Sometimes when the service is done the throttle body is not clean it minociusly and then it bring problem like yours.

It did say misfire on number 3 before cleared the code but after that the only code that came up was 2796

Dear customer, The number 3 means that it was a fail in the number 3 cilynder and theses codes are common to appear when a correct maintenance have not been done. And the cylinder could have present some dirty bits in some determined moment while you were driving and the dirty bit make the injector to fail and thats why that error were saved. It also could mean that the dirty bits were in the spark plugs and produce the error. These kind of error are saved in this way because the ECU does not recognize where exactly the fail was. As the error code you gave me its relate to the throttle body system it means that it need a in-depth maintenance that will sort out your problem. As i said before most of the times the maintenance done to the throtlle body system is not as exhaustive as it should be.

Indeed Dear customer. 98% of the times it sort out the problem.
