General common sense after reading this bit of info the Op stated;
"Sometimes it starts right up. Sometimes it turns over a few times and then starts. Sometimes it doesn't start at all. Usually it starts eventually. Problem used to only occur when the car was hot, now it occurs even when cold.
His MAF is in correctly. If its not throwing codes for the MAF or P171/P0172.... its NOT the MAF failing either. Next suggestion?
