ok i have tried to diagnose this problem my self but its not been working at all....what happens is when im cruising along the car will not take fuel it just sorta bogs out for a sec and then it takes it and it just chugs i've changed the o2 sensor and the fuel filter but what could be causing this to happen??? please help cause its really really gettin to me....thanks

 

ok ill giveit a try.//..,.,,. ok seeing how you have checked the fuel filter,.somthing i have not heard you say is that yer sure the fuel pump is ok.,.,i would be wondering what kinda shap it is in,.[working or not]

i have had cases where ive bought fuel pumps put themin and discoverd it was defective fromthe start,.,..(auto zone products lol.)
If fuel delivery isnot your problem then parhaps it is electrical.....And one ormore of the injectorsis not firing correctly there is alotof folks here who can assist with ways of testing the above mention parts.,.,good luck and keep us posted,.,.,.,.,.,.....,

 

my fuel pump does work because i did not have this problem until i took out my cat and replaced it with a straight pipe after i did that is when this problem started happening but my cat was hollowed out so... would vacuum problems cause this?

 

hmmm.,okay well hows about the cat? is there supposesd to be some kinda sensor like near it or realy close to it? if so perhaps thhe straight pipe mod whhould have alterd howit works and send msg to comp,. restricting spray from an injector?? if this does not make any sence to you,.then please disregard this feedback,. other then that the only other thing i can think of is the T.P.S .,,.,.ill keep serching

 

the only sensor that is near the cat/straigth pipe is the o2 sensor and i already changed that...im gonna go outside and mess with it tho see if i can figure out if i got a electrical problem or something thanks for the reply tho and if anyone else knows why this is happening please help.....thanks
