Help me troubleshoot this please!

ok ive had my car for about a month and a half - 2months. she eats gas up BAD... like a 30 minute drive will kill almost half a tank at normal speed just cruising! The engine is heavily modded, just a e303cam full exhaust and cold air. so it shouldnt be killin my gas like that. also it runs rich from when i start my car i can smell gas, while im driving, and until i cut it off i smell it. she idles at about 1200rpm. any ideas what could be wrong i really want to get it fixed before i go broke haha its rapeing my wallet!

1st check for codes. Check fuel pressure. I would guess its in need of o2's.

the o2 sensor looked new when i changed the starter. could it be spark plugs or vacuum line or anything else?

went to autozone they couldnt run the codes the cars to old so i gota find somewhere that can... errr ><

Dump the codes and see what the computer says is wrong…Codes may be present in the computer even if the Check Engine light isn’t on.

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great. You watch the flashing test lamp or Check Engine Light and count the flashes.

See http://www.troublecodes.net/Ford/

If your car is an 86-88 stang, you'll have to use the test lamp or voltmeter method. There is no functional check engine light on the 86-88's except possibly the Cali Mass Air cars.

89 through 95 cars have a working Check Engine light. Watch it instead of using a test lamp.

Codes have different answers if the engine is running from the answers that it has when the engine isn't running. It helps a lot to know if you had the engine running when you ran the test.

Trouble codes are either 2 digit or 3 digit, there are no cars that use both 2 digit codes and 3 digit codes.

For those who are intimidated by all the wires & connections, see http://www.actron.com/product_detail.php?pid=16153 for what a typical hand scanner looks like. Normal retail price is about $30 or so at AutoZone or Wal-Mart.

Or for a nicer scanner see http://www.midwayautosupply.com/pc-7...ader-3145.aspx – It has a 3 digit LCD display so that you don’t have to count flashes or beeps.. Cost is $30.
