Rev Problem

Okay if any bodies asked this sorry but cant find it. after turning on my 90 teg it about 10 min. later after warming up my engine light comes on and if you try to rev it up all the way it stops between 2000 and 3000 rpm. Does any one know why it does that or how i fix it ? :think:

did u mess with the ecu recently because that happened to me when i tried to put a power chip in it.

prolly in your dizzy (distributor)
had that happen to me after i mis-shifted

sounds like an ecu problem… (limp mode activation)
