Hey guys, i tried a search with no luck. Occasionally my tach will spike up 500-1500k rpm with no change in the actually engine speed. It happens only for a moment and sometimes happens when going over a bump while accelerating(or maybe its just coincidence) but is not due to the tires spinning in any way.
If anyone has experienced this or has any help on the issue id really appreciate it. My pcm has the connector issue that causes a stall but i have had a good temporary fix for awhile, just adding that in incase it might be a known cause.
