okay so over the winter my92 rs (stock 305 tbi)decide to turn into a huge turd. i used to get atleast15-17in town and about 20-22 highway....now i have a wonderfull 8-9 in town and 10-12 highway. so i figure i could do a slight tune- up and hope to god it saves me some gas being that its going to skyrocket in a few weeks.
i already know i need to:
change:
oil and filter
coolant
plugs and wires...
i was wondering if i should go ahead and change my injectors...cap/rotor...fuel filter or anything else...suggestions recommended....
thank you.

 

Depends on how much money you want to spent. I do recommend replacing the fuel filter.

 

I don't know much but I'll tell you...when I replaced my fuel filter my mpg increased right back to 18.
Of course after the mech showed it to me I understood why. So I totally recommend replacing the fuel filter.

 

okay, well money isnt really an issue since im spending to save. but when you save it shot back up to 18mpg, what where you getting???
