sr runs good when its cold out

[fenderguitarist]

been having trouble with my sr it seems to make awesome power when its under 25 degrees outside but as soon as it goes to 35 and above it runs like crap i dont think the change in outside temp should have that much of a effect im running bkr6e plugs in it now im also getting horrible gas mileage about 10 miles to a gallon at best any ideas on what the problem may be?

I would check your coolant temp sensor and your tps first. Hard to really diagnose anything like that without actually having the car in front of you.

bad o2 sensor? I am going to replace mine just to be safe... Our cars will run better when cooler especially with a large front mount on it. Something about ambient temperature of air is more dense when colder.....

Oh yeah the o2 sensor good call that can deffinetally cause poor performance.
