It could be almost anything however I would return to the shop that did the transmission work and have them check it.

SOURCE: accelaration loss of power

I'd have a fuel pressure test done to be sure, it isn't fuel related again. Takes 5 or 10 minutes so cost should be minimal. The other thing that comes to mind is a plugged exhaust. (catalytic converter) Quite possible on a 10yr.old vehicle.

SOURCE: idles poorly , and its like its starving for fuel or air

1. Vacuum leaks. Check all mounting bolts at the intake, check all hoses by wiggling them around. Listen with stethoscope or a length of fuel hose held up to your ear with engine running. You will be looking for a hissing sound. 2. Check egr valve. 3. Check air filter. 4. Check timing belt. ( you will need a timing light) If the mark is jumping around, your belt has jumped. If it stays basically in one place, it's good. 5. Check camshaft lobes. 6. Valves burnt or leaking. 7 Dirty or clogged injectors. 8 . Faulty idle control system.

SOURCE: Saab 900 auto with "Check gearbox" light

Hello. I had the same problem when the Check Gearbox light came on, it would be very sluggish. It turned out to be a small sensor in the transmission that lets the car know what gear it is in. It started to go out slowly and only sometimes would send the information.

My tuscon looses power intermittently, sometimes when accelerating, sometimes when just driving. It will do this for 1-2 days then will be ok for a week before doing it again. I can put into neutral a


Could be be clogged fuel filter or air filter or poor output from fuel pump. Low fuel pressure etc will cause it to "starve" for fuel. Clogged air filters will do similar thing causing it to choke for air. You said it loses power, does that mean it stops running and the engine dies or is it just not giving you as much acceleration as you need.

Could also be the drivetrain like torque converter or transmission depending on the model if it is automatic. If it is standard then it would not sound like a drivetrain problem, my first suggestion if to get your fuel filters cleaned and then have a fuel system cleaning done.


They will physically clean the throttle body and add a solution to the intake while it is running as well as pour an additive into the fuel tank.


First things first, fuel system cleaning, then fuel filter/s. Then check fuel pressure output.

Car shakes accelerating


I would have my fuel pump checked and a pressure test done on it to see how much pressure it is putting out also would check all the filters to the fuel filters and the air filters.this could be your problem starving for fuel. hope this helps,

Is this gas filter needed when car cuts off


it can be but their is many more various parts/components that do the same--bad gas--egr valve-restricted exhaust-air filter-fuel pump-catalytic converter--bad wires-plugs-etc. usually u will feel the loss of power on acceleration or feel the car starving for fuel --check fuel pressure or a fuel filter is easy and inexpensive enough to change and if it hasnt been done in a while good idea to do so

Lose of power on acceleration like its starving


Sounds like there is a load of dirty fuel in that gas tank. Ran good for a while after changing fuel filter, then began to run poorly again. Remove fuel tank, drain and clean out, replace fuel filter AGAIN. That should cure it. Hope this helps
