hi guys so for the past month ive been having issues with my 91 camaro rs 305. at first it was just back firing not often just once in a while when i stepped on the gas hard. now for the past week or so when i come to a stop light the car sounds like it is gonna just die it doesnt always do it but i have to give it gas to keep it running. then today i went outside to go run errands and it started ran really really rough then died. while giving it gas it sound extremly funky and the only way to keep the car on is to keep it at high rpms and putting it into gear it jsut dies. my dad and i were looking at the where the fuel is dumped into the tbi the left side if ur on the oustide of the car is awlays throwing alot of fuel but the right is only if u really give it gas or it jsut lightly gives some so often. not sure what the problem could be i jsut replaced the fuel fliter last week. any help would be great sorry for spelling.

 

Clogged cat maybe, symptomatic of an o2 sensor being out and the car running rich for a while.

 

how would i go about checkking this probem
