1993 Pontiac trans am
Well my boss's son just bought it. He was told to put the highest octane in it, but put in the regular octane and now if runs horribly. He wont even drive it.
She said it bogs and sounds horrible and runs like crap. Would it really be that bad because of the lower octane? I know the compression is higher in the LT1's and they recommend to use higher octane, but I don't know when they started putting in those engines. Is that what he has? Thanks

Ok do you think thats the cause of the bogging and knocking along with poor performance? I could see it being less powerful and some loss in gas milage but not that bad. But I'm guess the computer is trying to adjust and causing bad timing?

just running regular is not going to make that much difference. i have done it when i could get nothing else and it did not make the car run much difference. a little less umph at wot otherwise the same. i would say using regular made a little problem big. probly need some new spark plugs.

have a look at the plugs. if they look old then change em. the plugs on these are a pita to change so alot of people dont change them until they have to. both 93s ive owned had reallly old plugs in the #8 plug which is the hardest to change. the camaro i have now would not start the plugs were so bad when i bought it. got it home and it would not run the next day. man i was po ed.

well you can drain the gas tank or just burn it off if you can
