lots of hesitation upon acceleration…used fuel cleaner several times doesn’t work …what would cause this hesitation ?
of miles on the odometer?
What type of fuel system cleaner? (Many of them are of little use…)
Have you cleaned the throttle body? (It doesn’t get cleaned when you use a fuel system cleaner)
Is the check engine light on?
It appears that this is one more…drive-by question…with little chance of getting answers to the questions that we asked.
Has anyone tested the fuel pressure?
Causes of hesitation during acceleration
- Fuel pressure
- Deferred maintenance, esp spark plugs and ignition system
- Vacuum leaks
- Fuel injectors
- Crank and cam sensors
- Poor electrical connection, possibly at the battery
- Exhaust leaks
- Intake air leaks
