Im back again. I replaced the filter and took it to an old counrty road and opened it up and got it to about 85mph before the curve made me let off. Not a single problem. About two days ago i had to putt my buddies silverado in its place and once i hit 90mph+ the light starts blinking again. What is it now.
Thanks

 

Its a warning that your about to hit you rev limiter mine did the same thing only i was just cruising out to blythe california when mine started to do it!!

 

i wasnt near the rev limiter and i have shut it off before at 99mhp with no light

 

Have a new question. Please look.

is it possible the computer is a smart-*** and wants to tell you to slow down? haha

 

A flashing CEL means that the PCM has detected a potentially harmful misfire.

 

With a good scan tool, the computer will TELL you which cylinders it is missing on.

 

It won't matter whats causing the problem if youre not alive to fix it...drive slower
