Hi this is Carlos' wife...he wanted me to say thank you for the reply. I read your reply to him and he says he had jus put gas and within 10 miles after putting gas this problem happened. It was grade 93 at a bp station which he has used many times. The map he has is Stage 2, 93 octane.
Oh, he also said he probably did go over 5000rpm after he put the gas. It is a pretty safe assumption.
