New to the forum and a first time Toyota owner. Looking for some advice for my 2008 Tacoma double cab TRD off road. When I turn the key the engine will crank at least 5-10 seconds before starting. The truck has 117k and came from the southwest. Pretty dusty everwhere. The air filter is clean but I left the air filter box unsnapped (with a gap - several inches )for air and tried to start it. It seemed to start fine time after time. Could it be the inner or secondary filter is clogged or possible some sensor is going bad? Any ideas would be appreciated.
