i have an '01 acura EL with 95k on it and am experiencing a choking of the gas shortly after i start up the car and drive away (less than 1km). When i try to accerate it shakes a bit and decelerates then boosts up and accerates for a second. I pull over, stop the car and restart it and its perfectly fine!! This problem usually only happens when the car has been sitting for a few hours (but the last 3 days have had no problem, it only started again today!!) ive had the fuel injectors cleaned and the fuel filter. The engine light is not on and the mechanic i took it to drove it and unfortunately didnt have the problem so said the car was fine!!
some one help please!!!

it sounds like a fuel pump problem to me. it seems like when the car sits for a period of time it looses its prime and is pumping air instead of gas. causing the shake rattle and roll.
try this next time.
after the car has sit for an extended period of time. put the key in the ignition and turn it to the ACC position, you should hear a electric motor running in the back of the car for about 1.5 seconds. do that cycle two or three times (without starting it)
if your car starts up and runs fine right out of the barrel, then you need a fuel pump

thanks for the prompt reply... is there anything else (possibly less expensive) that could be the problem?? the car never actually stalls, does that mean that it cannot be the fuel pump? im concerned that the car is too new and too low on mileage for the fuel pump to go, is there any truth to this?
also, how can i go about getting the car fixed if the mechanic cannot experience this 'tempermental' issue?? any ideas on total cost for labour and fuel pump???

you never said if you tried the troubleshooting tests i told you. as far as age and mileage, i think its a reasonable time frame for the fuel pump to start to fail.

i didnt quite understand what i was supposed to be listening for when turning the key to the ACC position, and if i do not need a fuel pump what am i to be listening for??
but what i tried was to reving the car after turning it on. This allowed me to perhaps get any excess air out of the pump. The car hasnt had the problem when doing this, but i still feel there is something off.
any further suggestions?
and will a new expensive fuel pump be guaranteed to solve the problem??

Some possible confusion here. Fuel pressure and pump should be heard priming with KOEO = key on engine off. Better yet, take a pressure reading which will no doubt be good when it's not acting up so you'll have to catch it or notice the lack of it making it's buzz when it should.
To add: Who the heck told you that 95k and now possibly an 8 year old car is too new or low miles for any problem? A whole lot of folks struggle to get 120k and 10 years out of a car! There certainly are wild exceptions too,
T
Ps: Fuel pumps can go anytime or never but more common IMO in cars that are routinely run low on fuel as I'm convinced the fuel help keep electric fuel pump cooler

thanks for clearing that up!
so if i do hear it priming up (or buzzing) before starting the actual engine, would it not be the fuel pump??
also, a reasonable amount to pay for it to be replaced (part and labour?)

this could also be a distributor cap problem you may need to replace your cap and rotor, i had a problem close to your discription and it turned out to be a bad seal on my dis. cap was letting condinsation build up in my distributor causing misfires.

******************* It isn't necessarily the fuel pump but for the moment we can believe it works and if heard is getting power. You wouldn't just up and replace one quite so fast without seeing a problem with a pressure reading or knowing it has power and doesn't pump. You can check how much they cost at any parts store and ask for the "full" price as shops would charge that plus labor and many require removal of the fuel tank so it's no always so easy. I suggest more effort in diagnosing than just tossing parts unless parts (some things are dirt cheap) are easy, suspect and cheap to just try a new simple part vs spending hours figuring out if something is good, T
