Toyota Repair: 93 toyota celica, bg 44k, engine indicators

Question
I have a problem that just recently started. When you give it gas in any gear it stumbles or misses,until the rmp get up there and like a flip of a switch it will take off sitting you back in the seat.I ran some BG 44K injector cleaner through it,and it got a little better but far from right.What do you think it might be?

Answer
I just want to make sure you have performed basic maintenance on this vehicle such as air cleaner and fuel filter and PCV valve. Secondly, if you have more than 120k on the same injectors, simple tank cleaner will not restore them because they can leak. Lastly, do you have any service engine indicators? If not, you can usually solve this by putting new plugs and wires in the vehicle. If you do have a service indicator light illuminated, you may have an O2 sensor problem. Most parts houses will check this at no cost.
