10mpg wtf
 

so my 83 is only getting 10mpg is this normal ive only had the car for 3 days im going to give it a good once over tonight my trailing igniter is down at the moment could that be part of the problem?

what other mods do you have done? A was getting 10-12 with my dellorto and a holley fuel pump and headers on a street port.

as far as im aware its bone stock

Not normal, for either one of you. Trailing ignitor makes a small difference in mpg, not 50% though.

Tell us more about the car, how it runs, history, etc.

Whoa. I joke about getting 10 mpg a lot, but never have I even came close to actually getting 10 mpg.

Definitely fill us in on how its running and stuff.

well im not to sure of its history but it would appear the motor was rebuilt sometime in 2003 judging by the stamp on the side of the housing. its got kind of a lumpy idle but is smooth when your driving it has newer ngk plugs and wires i was going to pop the cap off and see if they need to be replaced probly needs a new fuel filter too.

im planning on putting a msd blaster hvc{pn# 8222}coil into tonight any thing i should know before i do that?

Lumpy idle??? I thought all rotaries had that lol. Mine does and she runs great (and shes stock)

so the leading coil is the closest to the head light right i was jsut looking at my dist cap and the first coils on the spot marked l and the second coil is on the spot labled t would that affect my cars milage if thats the incorrect way to be set up?

I posted in your other thread, but, when the engine is running, pulling the trailing plug wire will make little to no difference in idle. Pull a leading one make a major difference, often killing the engine.

my poor opinion
cap
rotor
fuel filter
rape the carb with carb cleaner and hit it with a hammer
could be something clogged in the idle circuit

have any glowing cats yet???

I calculate everytime I fill up, and I average between 15.1mpg and 15.8mpg.

S5 N/A streetported with RB header/presilencer and a Mikuni 44. Needs to be tuned, I know...

havent seen/smelled my cat roasting yet cap/rotor/plugs and wires all new im going to do the fuel filter this weekend carb was rebuilt about 8k ago

have you checked your air filter yet either? if that beast is clogged up can cause a world of hurt depending on how bad, but you have yet to beat my mpg ratting i used a whole tank of gas in less than 45 minutes because of a combanition of things so beat that ahhahah!! i got about 25 gallons to the mile ahhahahah beat that! btw i think the oil companys must love me!!!

im might as well repalce all my filters while im at it. its way to wet here to work on my car right now id need a raft to get to the parts store.
