engine missing ,wrong octane?

I forgot when fueling up about a week ago, I put 87 octane in tank approx. 17 gallons.. Now it seems to be missing when starting out from 1 to 2 and 2 to 3, seems to run better when out in the highway at 55 to 75. Is it do to me putting in the 87 I was using the 93 the last couple of tank refills before. Didn't notice this til now.Can someone give me some advice I'm a new 2 week owner of this c4. Brent317

1 week ago.....I assume you've used some of the fuel by now. I would go down to the station and top it off with 93 octane...and keep doing that. If it's the octane, it should eventually straighten itself out.

Aint the octane! Low octane causes pinging, not missing. It would be a very good idea to fill with 93 to increase the octane.

I see you have a '95, yes 87 is too low. LT1's have a 10.4:1 compression and need that high octane gas.
