Opti Diag
94 LT1 in a 90 K-5 Blazer
ok, when cold, it is fine, but once it warms up, the engine stumbles and it sets a code for High Res Pulse Failure, I checked all the wiring and all looks good, no corrosion, ect.
if I let it cool off, the code and stumble stay away until it warms up again
sound like the opti?
