Fuel system troubleshoot?

[91s13ForMeeh]

Whats up guys? I recently picked up a s13 coupe and she seems to guzzle the gas. I Filled the tank The otherday, drove almost 200 miles and I'm now below empty. No engine mods either. Just a straight pipe from the cat back. Any suggestions? Clean air filter cleaned maf, changed oil+stabilizer plugs are good too.

Check your lines you got a leak most likely.

how about fuel filter

Hmm. Seems as if the leak is coming from the injectors. I was Just going over the fuel system and I found that 3 of my 4 injectors fall out of resistance specs. Think this might be a result of the straight pipe and back pressure issues?

Most likely just old worn out injectors. Mine are like that now.

Well the injectors were off spec by about an ohm. I talked to my instructor at school and he was saying I'm fine and to leave them. I'm still not getting the mileage though. I'm somewhere around 23-24 mpg. It'd be nice to get that extra 2-3 mpg. Anyways I went to smog it the other day and it failed. Gross poluter and evap system leak test fail. It turns out my fuel tank gasket wasnt sitting right. There's our evap issue. Second of all my timing was at 8 degrees! FYI I just picked the car up. Advanced timing etc. HC fail @ 100 ppm or so.. Jesus my truck just passed at 11 hc ppm. Gotta be my cat. lolz:x:
