map sensor
 

can a map sensor contribute to bad gas millage? right now im currently averaging about 180-200 miles a tank. i think that it is rather low. i also think my ignitor inside the distributor is going out as well. all this is one a pm6 ecu from an 88 si rex. i still think i should be at least getting 300 miles or just under it for millage. then again this is on a 4 speed trans....maybe thats my culprit.

4-speed should get good gas mileage long gears=good gas mileage. U car running with any CEL's? do the plugs look like their from south africa?

Re: map sensor
 

no, plugs are good and clean. and im throwing no codes at all.

i just dont understand. i dont beat on it. i do a lot of highway driving to school and back about 30 miles round trip 3 times a week and get my running around town done.

it just seems to low for millage on a single tank.

could it be a clogged or dirty fuel system? or even a dirty fuel filter? i dunno im stumped on this.

Re: map sensor
 

if you have never replaced fuel filter do so

Re: map sensor
 

since i am mpfi now. should i replace it with an si fuel filter or just the dpfi one the car is equiped with. or is there no difference?

Re: map sensor
 

if there is difference it isnt anything that matters

Re: map sensor
 

yeah just found listings online. they are the same for all the fi models. other than a fuel filter would you recommend anything else get replaced?

any basic tune up stuff



mileage should be in the mid 30's sometimes you can get more but anything in that range your where its suppose to be
