hi,

i got a 90' protege . my exhaust always boggs out
during deceleration / down-shifting after the car
has been running for 5-10 mins.

i think this is natural for loud exhausts but i dunno.

i changed my fuel filter (it was pretty dirty). that helped
keep the bogging to a minimal. that farting noise is
still annoying though.

anyone have suggestions to stop the bogging?

i hear a good intake should help.

anyways i want everyones opinions.

Thanks!

Can you elaborate on the boggin sound. Does it pop? Try redline injector cleaner, good stuff. Did u put a new exhaust? Is it a DX or LX.

it is a 1990 mazda protege lx

the exhaust is kind of old.

as for the bogging noise it farts straight up, put it that way.

sounds sorta like this (puttuhp puttuhp putt putt puttuhp).

only after i gas it more the bogging noise stops and holds
a cleaner sound.

as for redline injector cleaner....... is that the same as
normal stp injector cleaner because i use that and it doesn't
seem to help.

thanks.
