pressure

This is to supplement the discussions on reflashing the ECU. At wide open throttle the motor defaults to open loop and dumps in all the fuel it can resulting in an over rich mixture of around 11:1 or less. Ideal is about 12.8-13:1. Stock fuel pressure is regulated at 55 PSI. Reducing this fuel...

Hi, I have a 2009 Genesis non-tech package. I am having a very weird issue with my car. I get TPMS sign come on multiple occasions in the panel even if the tire pressures are good>33lbs. It happens only when the car lights are on( driving in dark or in early morning). Its not related to weather...

My low tire pressure light just came on. I havent had time to take it to the dealer as yet. Can anyone tell me if theres a problem or it just has to the with the cold weather, this is the car second winter, first winter no low tire pressure issues.

As you all know the Genesis sedan has a TPS that notifys you when your tire pressure is too low. Well, I lowered my tire pressure to 31 lbs which made my car ride a lot better. However, not that the outside temp is colder (32 degrees) that has lowered the tire pressure and caused the TPS to...

The tire pressure indicator came on this morning and I took it to the dealer and the service manager said one of the front tires was at 32 psi, which is a bit too high. The manual states "This warning lights will also illuminate if one or more of your tires is significantly under-inflated."...

I've had my 2010 Genesis 3.8 for about 4 months so far. No problems until a few days ago when the TPS light came on. Since then it comes on everytime I drive. I checked the tire pressure and they all show the same... 35psi. Why does this TPS light come on? When at the dealer, they said cold...

Tires with max pressure of 50 lbs. Anyone running higher than 32-34?

There should be an optimum tire pressure for: mileage handling comfort. Are they the same? My 2010 v6 says to inflate at 33 psi. Is that optimum for all of these things? Do the rest of you use 33? I recently discovered that my tires were inflated a good bit higher than the 33. I had not...

I'm currently at 30psi all wheels.

I'm sure people rarely do this, so I'm sending out a PSA. Please check your spare tire pressure. It's dropped to a frigid 47 degrees in LA :D. The spare had 45 psi, when it's supposed to have 60. Carrying around a spare with no air, is like carrying around a gun with no bullets, kinda pointless.

Anybody else having issues with the tire pressure monitoring system. My light came on a couple days ago so I checked the tires right away. All tires looked full with no signs of a flat or leaking air anywhere. I went to the gas station and three of my tires were at 34psi and one was at 33psi...

I have a 3.8 and the pressure from the dealer came with 33 on the fronts and 33.5 on the backs. The recommended pressure is 33 psi and I think that the tires are rated for 51 psi max. Anyone using anything different and is there a tangible difference in the ride? Also, if you over or under...
