why does my 1992 toyota 4runner continue to choke out when reaching 3rd gear?

what about the filter??? you also could have crap in the bottom of the tank clogging the pick up screen for the pump. also, i would look at a cat converter. it may be failing. have a shop test it for you. Roy

panterakein, It is pretty hard to install the filter wrong as Roy said, and he is also correct that you could have a problem with the pump, or dirt in the tank or a Catalytic Converter starting to fail. There could also be other possible causes for the symptoms you describe but it is impossible to give a diagnosis or troubleshoot based on limited information. I recommend you have professional mechanic check it rather than guess at what it could be. The mechanic will need to confirm whether the problem is fuel related, ignition related, or a restricted exhaust. Once this is done the problem can be isolated.
