The past two mornings when i go to leave for work my truck will start right up but then the rpms will go up and down. Once it warms up itll settle down but randomly when im driving the rpm will just drop from about 500 rpms n the truck will jerk back then go back up to normal. Now after it sits at work for 11 hours itll drive fine no rpm issues at all. Anyone have this problem before ive looked into it a little and from what i got it could be the iac maf or tpi or the fule pump itself thanks for any info you have
