Hi Peter. I have a strange
Hi Peter. I have a strange problem.
Mileage is 125000 miles.
Very nice oil. Not black or seared.
Does not take and oil or coolant. After driving a lot.
Started with cold start knock/misfires.
I have.Changed./replaced.
New Coils on every cylinder.
New denso original plugs.
Cleaned intake manifold.
Throttle house.
New gaskets.
Maf and map.
Egr and egr cooler. Replaced to other not new but ok and cleaned of course.
It was working nice but still not always perfect .
To see and understand better I got a scanner and it occasionally sends cylinder 1 misfires.
It has never showed any engine warning signs at all..
Still it sometimes could cold or warm engine misfire on cylinder 1.
I replaced the fuel injector after cleaning them first still no difference.
After replacing the fuel injector it was even better. Still.
After standing a day or to it can send misfires on cylinder 1.
I have noticed.. if I press and accelerate hard and drive it hard for a while...it can send misfires just when the engine is about to stop. Its like it cannot decide what to do?..
Have you any suggestions?..
