Question about 2002 Ford Taurus

1 Answer

Bucking on Hard Acceleration

Car runs fine under normal load but at highway speed, if you need to accelerate quickly, the car will buck. If you let off on the gas a little, the bucking stops. It seems to be hunting for a gear (automatic transmission). I think it's a vacuum problem but I don't know where to look.

You best bet would be to look for the vacuum diagram and just take a day to make sure all of the lines to the engine and tranny are all correct. If its not it and while bucking the car feels like its going to turn off on you then it maybe a fuel delivery problem.

Car "bucking"


Are you pulling a trailer or have a heavy load - you should not drive in overdrive in those conditions. You will eventually ruin your transmission.

While merging onto the highway when my car hit 3 and 4th gear the engine seemed to "stutter/misfire" during harder acceleration. Check engine light also flashed briefly during hard acceleration. Dur


Could be a transmission problem or something as simple as bad spark plugs.
The engine is under the most load when RPM is low and you are trying to accelerate, such as when it upshifts.
You should have the computer checked for trouble codes and hopefully that will point you in the right direction to test.
If the spark plugs have more than 50,000 miles of wear you might start with replacing them.

It could be a single ploblem or a combination of the fuel system the engine could be starving for fuel or air or the timing is not set correctly. The transmission may need some adjustment.

At highway speed, as the car transitions from a set speed to slight deceleration (slight easing off the gas pedal) or from a hard deceleration (foot completely off the gas pedal) to a very slight...


sounds like your egr valve is opening too far at part throttle and sticking open. it is actuated by solenoids that open and let engine vacuum in. you were on a good path in checking the vacuum lines. however this may require replacing the egr valve and gasket. the egr valve is circular in shape on top and usually is bolted down with two bolts. its located on the engine side facing the firewall.

2003 Lincoln Navigator stumbles/bucking under mild acceleration


I have a 2003 Nav with the exact same problem. I've found it diminishes when taken out of overdrive. Also it's intermittent but more towards bucking. Sorry to post this under solutions.

Engine light,poor acceleration and bucking from engine


The evaporation canister can cause this, so would any vacuum leak. A faulty throttle position sensor or camshaft position sensor would also cause this but it would in the diagnostics most likely.
