Alright so I've been having cold start problems. When I try to turn it on in the morning, it runs rich and boggs. Also, throws me a code 22. After around 10-15 mins of warming up, check engine light turns off and truck runs fine. Changed the MAF sensor and nothing. Help please
yup, that would do it. there's a thermal switch that controls your "cold start" process. this adjusts fuel and air for start up. did you check to see if the sensor came undone? possibly disconnected? otherwise, swap it out.
Check ur temp sensor for continuity and also proper specifications. Boil water and check the ohm load resistant. And also check ur cold start injector also. Ur sensor may just be dirty from dirty coolant so its reading bad. Remove and clean it with a fine wire brush. Good luck!
