Car hesitation between 25-35mph
I have nissan altima 2007 3.5 with 359k miles Cvt transmission/ timing chain
when i accelerate from stop, theres like a hesitation/sputter between 25-35mph After i past 35mph the car accelerates normally. But the feeling is even worse going uphill.
The car has a oxygen sensor code and theres a leak in exhaust manifold which makes the engine sound a little louder but its been like that for years, never had the hesitation problem before.
spark plugs and coils were changed 2 years ago
engine filter was changed recently
car idles fine at around 750rpm
ive used injector cleaners
engine oil and transmission fluid is at correct level.
