Same exact thing happened to me in my truck. I cleaned my MAF
and my throttle body. It did wonders for my truck and its not anywhere near as hard to start after its been running. For the price of a can of MAF
sensor cleaner, its worth a shot to see if this will help you like it did me.
When I cleaned my throttle body, I just took the same MAF
sensor cleaner and squirted a little bit in. Took an old tooth brush and scrubbed scrubbed scrubbed.
Let me know if this helps you out!
