so i just bought a 97 cobra today, paid 5400, has a lil over 100k miles.....well it has a miss, but ive noticed after I let the car sit for a while it wont miss and will actually run great...the guy i bought it from told me that he put in reg. unleaded fuel instead of the recommended premium fuel but I wouldnt think thatd be the reason, i even filled it up from a quarter tank with premium and it still misses. my biggest guess is of course the fuel filter but figured id see if anyone else has had the same problem. also he changed the plugs to E3 plugs which ive heard from a couple of friends that they dont like them, maybe thats another possibility?
