Default P0087

Hi Rich,

I agree with the dealer that opening up the exhaust would help cool the motor by lowering the EGT a little. I do not think it will get you a substantial drop in fuel temperature. Additionally, the noise caused by most large exhaust systems will make for a very long trip from Illinois to Arizona next year.

My post about the P0087 code was the one posted just before your post (take a look). If I keep plenty of fuel in my fuel tank it seems to cool the returning hot fuel and stop the P0087 problem. When your truck threw the p0087 code did you have over half a tank of fuel? I think a second fuel cooler would cool the returning hot fuel a lot better than a larger exhaust system. Just my thoughts on the P0087 code.

Good luck
John
