HELP! I've tried everything. Car has been bucking and hesitating upon acceleration for months - but running good at higher speeds. Check engine light came on last week. 4 months ago had tune up: fuel filter, NKG spark blugs, igntion coil, distributor and rotor. Wires Bosch were fairly new and looked ok. When light came on took it to Autozone - PO032 engine misfire. Replaced all four injectors and one spark plug in the misfiring cylinder. Added octane booster as well. (see,s to make it worse - should I siphon out?)
Car runs as bad as ever - no power - check engine flashing, still reading PO032 and also P1399. Do I need to take it to dealer? Is it valves, converter, O2 sensor. (Also does seem to use oil faster than normal, but don't see a leak. ) No funny smells ever.
I am at a loss and could really use some advice. Thanks
Kim

Hi kimberly600,

The codes that you have provided does not seem to match those in my database. Can you please reconfirm if they had been typed in correctly.

Bucking upon acceleration usually are caused by sparking problem and it could be any of the following.
1. Spark plugs. Check if any are fouled and/ or misgapped.
2. Plug wires. Check if any is not seated properly or has broken internally, use an ohmmeter to test the resistance.
3. Distributor cap and rotor.
4. Throttle position sensor.

Is the Check Engine Light showing?
