![Question](https://www.clublexus.com/forums/images/icons/icon5.gif)
Was just wondering if anyone has an issue like mine. Whenever I step on the gas from a stop my car doesn't respond right away, causing a hesitiation. It almost appears like the throttle has a dead spot...

Hey, do you have any mods on your car? The main one in question here is the intake. If you do make sure you have that MAF sensor SEALED UP GOOD!! Any air leaks at all and the car will feel like you lost half your cylinders.
If no intake. Try to clean your MAF sensor and reset the ECU while you're at it. If you aren't sure how to do those....just do a search and you will get loads of how-to guides.
Good luck!

Make sure you use premium gasoline. I had a similar problem when I used 89 octane...bad choice. I only saved about 4 dollars on a filiup. With 93 octane I can

I put about 30,000 on my GS3 every year, and I notice a lot of difference between premium vs. regular or plus versions of gasoline. i get much better mileage and the car always drives smooth.
however, sometimes i catch the dead spot too...its funny because my car will pick up, then pause for a second in the middle of my pushing the pedal down to accelerate, then catch itself back up after i take my foot off the pedal or wait for a few seconds. at first i was worried but now it doesnt faze me too much...but i hope this isnt a bad sign?

After about 5 gallons I realized what I had done, cussed a few choice words, but went ahead and finished filling the car up. 392 miles on that tank of gas and I didn't notice any difference!! I expected to have hard starts, rough idle, poor performance, etc. etc. but nothing out of the odinary happened, was it just luck or does it take many tanks of regular to throw it off?

The onboard computer will retard ignition timing (to eliminate engine knocking) when lower octane gasoline is used. The car will run on lower octane and under normal driving you can't tell the difference. It's us lead foot junkies that will testify there is a big difference in power.

I realize this thread is coming back from the dead, however, I want to add my very simple 'fix' for this hesitation issue. My 02 GS300 was also experiencing the dreaded "go delay" when hitting the pedal from a dead stop. In my case it turned out not to be some fancy computer related calculation causing the pause. It was slack in the throttle cable! I tightened it up enough to pull the slack out of it.. and now that slop in the pedal and hesistation is completely gone. Car idles & drives just fine - only better. Just wanted to add that for those of you that may not have thought of it.
