what is the best way to bring back your car performance? as in without mods...like cleaning out throttle body and stuff? just curious...thought maybe its time to give my max some nice cleaning to restore power.

 

tune up, bizznatch.

 

tune up, and a nice wash

 

selt belt shoulders pads release about 10 lost hp from over the years.

 

Check for the famous ghost code 0304 (knock sensor)..replace if necessary and this should bring back the performance.

 

You could run some seafoam through the motor, if there's any sludge it usually helps out a bit.

 

Ditto.
Nice wash and wax job... dirt on car can cause noticeable air friction. Sounds silly don't it?

 

Use some Engine Restore or Lucas Treatment from AutoZone. Run some seaFoam. Uhh......TTTuuuuuurrrrrbbbooo.

 

plugs, new oil/fule/air filters, check for 0304, get injectors cleaned, clean TB/upper intake manifold, use some seafoam, engine restorer, check coil packs, change blinker fluid, and recalibrate the flux capasitor
