trans started shifting hard and check engine soon light came on today
Difficult to start, I have to crank the engine 3 to 4 times.
Fuel pressure ok, new fuel filter installed.
Is there like a throttle solenoid or something causing the problem? thanks
- A leaky fuel pressure regulator
- A small vacuum leak
- Intake leak
- Sticking IAC valve – most common
We are assuming the check engine light is not on.
