Ok so I put a sr on. When I didnit kinda acted like there was no third gear and had no power at all when you have been cruising at speed for a min then push the gas down. It'll hold at 3k with no oomph till you hit the floor then it will downshift to 2nd and scoot. Another thing is when I accelerate from a stop with full throttle it doesn't go smooth it kinda jumps and hops as it goes into higher rpms.
sr=SRI? take it off and re install stock airbox. If it continues to do that, my question would be: Was your vibe part of the PCM recall? That caused me some real problems
