The check engine light popped up this morning on my 2000 Ranger 4.0L. It did this the other morning as well, but I was in town and went to Autozone for the code. The codes said was running lean, and first to check the mass airflow sensor, then fuel system (pressure).....I started cheap and cleaned the MAS, drove it a couple days with no check light, until this morning....but it was 7 degrees too.....

Anyway, I want to know if I can use my Diablo Predator tuner to pull the codes on my Ranger without causing problems to the truck or the tuner....Tuner has a canned Steeda 91 octane tune on it and nothing else, not sure if that matters.

Please inform if it's safe to use on the truck!! Thanks
