just got a quick quesion
ive been noticing lately that my car is starting to feel sluggish in 2,3,4 gear from about 2500 to 3800
but its not an every time thing
i talked to someone that i know and they are leaning towards a bad cat and said that in higher rpms that the boost willl overcome the pluged cat

well i am not staged yet with only a intake as a engine mod
the downpipe was just rteplace about 15000 miles ago
i often times run race gas for the smell and within the last 3 months race av gas and heard that it runs extremly hot

what do you guys think that it could be


thanks

well gotta be the worst turn out for a thread on this site in history 30 min 1 view and no replies

 

A great way to know if its a clogged cat, jack up the car and knock on the cat. If it rattles its bad. I'm leaning towards a clogged fuel filter.

 

what kind of rattle would i be looing for like a holow sound

 

It'll sound like a rattle when you knock on it. If its just a typical metal knock noise then its normal. Knock on another part of the exhaust and see if you hear a difference.

 

k gong to \check

well sounds exactly like the rest of the exhaust
so were about is the fuel filter on these hogs

 

um if you dont know, the "av gas" aviation gas is leaded which will ruin the cat and drastically shorten the life of o2 sensor so "just for the smell" is a bad idea...

its in the back under the trunk it has two lines on one side and one on the other

 

leaded gas is bad for cats and o2 sensors

 

the guy thatsold it to me at atlantic airlines that it was 100octane unleaded and i only ran 5 gallons of it threw

 

the fuel filter is deff worth a try how many mi you got on her

 

41k


i was talking to someone and they said to keep with the stock brand(40 dollars)
instead of cheap at auto zone 10-15 dollars

 

Any name brand fuel filter will suffice.

 

deff the filter replace sunday runs much better

 

i feel the same, get a fuel gauge and see what the psi is around that rpms
