Markus56 Posted August 4, 2009 Share Posted August 4, 2009 (edited) my 1990 loyale spfi 5 speed single range 4x4 is getting 14 miles per gallon. which sucks. My carbed wheeler wagon with a craptachi and 28's is getting 26 mpg, so i know the loyale should be getting better milage Does anyone know what is making the loyale have crappy gas milage? What should i do to fix it? Thanks! John Edited August 4, 2009 by Markus56 Link to comment Share on other sites More sharing options...
casm Posted August 4, 2009 Share Posted August 4, 2009 (edited) Does anyone know what is making the loyale have crappy gas milage? What should i do to fix it? Okay... What have you checked so far? I'm not really up on the EA-82s, but here's what I'd go through on pretty much any car; modify recommendations as necessary to suit your situation: - Is the math on the fuel economy correct? (I've got this one wrong before) - Is the fuel you've got OK? (drain / run out tank, fill up at a different station) - Spark plugs (cracked, worn out, what sort of colouration?) - Plug wires (are they oil-soaked, cracked, and / or showing arcing?) - Distributor cap (check for cracks and broken / worn contacts) - Rotor arm (check tip and centre for wear) - Ignition coil (if you shake it, can you hear the oil sloshing around inside? If not, time for a new one) - Fuel filters (clogged / cracked?) - Fuel lines (cracked?) - Vacuum leaks (got any?) - Timing (no misses or flat spots, distributor / shaft bushings OK?) - Carb / FI (is it running rich or leaking; injector(s) & sensors OK?) That's more or less the order I'd check it out in. Need some more info before we can really give you an idea, though.

Markus56 Posted August 4, 2009 Author Share Posted August 4, 2009 yeah, i should probably do that. i was hoping i wouldn't have to spend money but i guess it will save me money in the long run :-p Link to comment Share on other sites More sharing options...
casm Posted August 4, 2009 Share Posted August 4, 2009 yeah, i should probably do that. i was hoping i wouldn't have to spend money but i guess it will save me money in the long run :-p Nah, just check the basics yourself first. A lot of this doesn't require specialised knowledge, just the ability to pull spark plugs, unbolt a coil, etc. If you can get us whatever you can, it helps to track stuff down - which in turn can end up saving you money even if you decide to have someone else do the work.

Markus56 Posted August 4, 2009 Author Share Posted August 4, 2009 I meant spending money on parts. but when your car has 260 thousand miles on it, you should probably replace the old stuff on it Link to comment Share on other sites More sharing options...
