im having problems with my fc right now...i have the 13b and it started for a while, it always does some backfire, i have a bad idle and it runs too rich on gaz, i was just wondering what it could be, also right now i only have 1 muffler because the other one fell off 1 week ago lol, if someone could tell me what might cause this?

 

yeah but ya gotta give us way more info than "runs bad on gaz" or "why did my muffler fall off". just the way you worded everything made it game for people poking fun at ya.

 

Should always start with a compression test to elimate the internals of the short block being bad. Do that and let us know the results.

 

Has the car had a tune up/basic service in a while? Stuff falling off is either loose or rust maybe, look under there and see what's up.

 

check your compression and timing too.

 

Sounds like the car is in pretty poor shape, and likely just needs a tuneup. Full tuneup procedures are covered in the Factory Service Manual, which is available for download in the FAQ.

Also, driving style has a HUGE part in mileage.
