'95 Hyundai Accent Problem

My friend says that when it's really hot out and you press down on the gas, there's a pause before it accelerates. This doesn't happen when it's cooler out.
Any ideas?

Perhaps it's because the a/c is on when it's hot. Could be a host of things, really. Loose connection at MAF or TPS. Ignition breakdown. Coolant temp sensor.

Hmmmmm HT could this be the problem with my 2005 XG350L, I live in Las Vegas and it seems lately that when I first start up in the AM there is a slight hesitation when I step on the gas for the 1st time. The air is on ( never turned off untill about Oct 15th ) and the temp has been in the low 100's for like forever. It seems like a really deep hesitation and only does it just the first time, the rest of the day its fine
Thanks ahead of time Tunez

On something as new as your 2005 XG, I'd suspect a PCM programming issue. I checked for reprograms, and none are available.
You might try reinitializing the throttle to see if that makes any difference. Simply turn the key to the on position (do not start the car) and immediately back off. Then wait at least ten seconds. The throttle will perform a sweep to initialize.

I've been experiencing something similar recently with my '96 Accent: An intermittent, noticeable loss of horsepower. Usually on acceleration, but occasionally at highway speed. Codes checked clear, fuel pressure ok, replaced plugs and wires (needed it anyway), replaced fuel and air filters. Ran out of ideas and took it to local shop, who cleaned... emissionssomething (lost the receipt, doh!).
Acceleration improves within 2-5 seconds of the power drop, but I'd rather it work properly. Seems to be weather/temperature independent, but I've not tracked that too closely either. No rough idle nor smoke out the exhaust (nor anywhere else for that matter).
Thoughts?
