On my 01' 2.4L Alero when I'm in park I can only get up to around 4000 RPMS.... no biggy. But the main reason for this post is that when I "put the pedal to the metal" when driving it doesn't accelerate as much as it can right away, it will accelerate slow and then after a few seconds(if that) BAM! It kicks in.... it's quite annoying.
Also, what do you think is a good first upgrade, I'm thinking exhause but I don't know poop so I'll ask you guys
.
There will be more later
