fuel additives

Dont forget to check the O2 sensor and MAF as they tell the engine JUST how much fuel is needed to maintain a proper A/F ratio,

also if you doing the plugs you might want to also upgrade the wires and coil (MSD is a good one)

Fuel additives you buy at walmart ARNT power adders

THIS is a power adder

when is the last time you replaced your O2 sensor and plugs?

Might be a good idea, get a bosch one

also the plugs would be good too, I got the P4s and I noticed a little difference at idle and acceleration, I probably wouldn't of gotten them except I got a killer deal on ebay on em'

hmm is there only 1 02( oxygen sensor ) on the car?

 

[SuperchargedRS 10+ year member]

depends on the car, but I would guess on yours that would make sense, you can always ask one of the monkeys at the dealership, then go to kragen and buy one (or ebay if you can wait).

hmm i c how much MPG's do ppl usually gain after getting new 02 sensor and MAF

 

[SuperchargedRS 10+ year member]

Depending on how F'ed it is and your engine I would say 5+mpg for the O2 sensor

also you can test the O2 sensor with a accurate multimeter, or just get a new one for like 50bucks

clogged MAF can cause the same problem you can clean your MAF if you want to save money (as MAFs arent cheap here is how)

use ELECTRICAL CONTACT CLEANER. This is the only thing you should use to clean your MAF. Only ELECTRICAL CONTACT CLEANER. No windex, no carb cleaner, no brake cleaner, no rubbing alcohol, and no Q-Tips.

Step 1: Open the hood and locate your air box. If you can't find it...please stop right now and have a friend clean your MAF for you.

Step 2: Open the airbox and move the assembly up to give you room to work.

Step 3: Locate the plug on the bottom and move the grommet down to give you room. See picture.

Step 4: Take the flathead screwdriver and pop the four tabs holding the assembly in.

Step 5: Reach in and disconnect the wiring harness from the MAF. Don't rip the wires or anything!

Step 6: Remove the assembly. Locate the MAF and remove the two screws holding it in.

Step 7: Spray the living daylights out of the wires. Do NOT touch them. ABOSOLUTELY DO NOT TOUCH THEM. Those wires are very small and delicate. If you break one of them....it's a $150 mistake.

Step 8: The installation is the reversal.

Do this once every 6 months and your MAF will continue to be clean and your performance won't suffer.

ALSO dont forget about your plugs and wires

hmm i might have to give it a shot

hmmm i think i might go clean my MAF too. I've read you'll get better performance out of copper sparkplugs but they don't last nearly as long as platinum. That's a 6 cylinder right? You might have 2 02 sensors, that could be expensive to replace. I know my ford 3.8 has 2 after the cats.
