yes, yes, yes i know its the little 3.1 liter engine! i love grand prix's and when i bought this car it was the nicest one i could find in my budget (i was really pushing for a 3.8 but couldn't find one in my price range) so im from MA and i have a 2002 grand prix se, im not looking to really soup up my grand prix because i know that i am better off saving up for a nice 3800! but i am looking to get little bumps here and there! so far i have replaced plugs and wires and just slapped a spectre filter right on the end of the MAF, nothing special but it was cheap, got me better mileage/more responsive and pretty easy!
