Is your car overheating?
When did you last change your oil, fuel tank level?

Clean your MAF for starters. With a change in temperature comes a change in air density. Definitely check your oil levels and coolant levels. Low oil pressure can create bogging down and stalling.

Check hoses and electrical connections and make sure they are in place and tight.

I forgot, you're probably at height in Colorado. So air seems the most likely suspect. How old are your O2sensors?

shouldn't he get a check engine light if that was the case?
OP are you tuned for the mods that you have?

O2 failure symptoms can occur way before a CEL appears.

you know now that I think about it I did have that happen to me with my old integra before I actually got a check engine light

here is a way to test it electronically:
Make sure the engine is cooled down before removing the oxygen sensor.

1. Remove the oxygen sensor from the car.

2.Mount the oxygen sensor in the vise and then connect the negative voltmeter lead to the case of the sensor and the positive lead to the sensor output wire.

3. Light the propane torch and heat the fluted or perforated area of the sensor. Voltage should shoot up to 0.6 or higher within 20 seconds of heating. If you see the increase in voltage, remove the flame and watch for a drop to under 0.1 seconds. If you do not see the fluctuation in voltage, the sensor is probably fouled.

4. Heat the perforated section of the sensor for two full minutes and watch for drops in voltage. Sometimes the connections will open up under heat and act the same as a loose wire. If the sensor fails this "two minute test" then it needs replaced. However, if it does not have sharp fluctuations in voltage under constant heat and it shows a difference in voltage with the addition/removal of heat, then the sensor is fine and can be remounted

the car is not tuned at all i have an sri intake manifold udp and 2 1/2" exhaust. but thees mod were on for about a year already and the car has been fine idk how to tune it because of the altitude i would need it tuned in colorado because of the elevation

umm 4k ago the oil is royal purple but still i probably should change it already
the car is not overheating
fuel was 3/4 full maybe bad gas? so it might be throwing more air in to try to level things out? idk.....is that possible?

Read his original post carefully: I answered one of his questions. It is helpful to know if such overheating is typical of Ralliarts.

So spend your time trying to formulate an intelligent response to his query instead of criticizing a perfectly useful and valid response from someone else.
