higher mileage recommendation

hey all! I stumbled upon two maintenance items that I recommend all the higher mileage peeps do.

1. O2 sensor replacement/cleaning. my upstream O2 sensor died and after I replaced it the driving response was greatly improved!

2. MAP sensor cleaning. my engine has been pulsing under high load and I couldn't figure out why. cleaned this puppy and yet again, car driving and response got EVEN BETTER!

hope this helps!
