Hey, first off i have a 1986.5 toyota supra N/A 7m, i was driving last night and it was fine i was on the highway and everything and i almost got home and then the engine started to idle weird so i shut it off and did a quick visual check and nothing seemed out of place, at first it sounded like a missfire, then i tryed to limp it home and it developed a horrible almost ticking sound, sounding like it was coming from the engine or trans, i just did an oil change so maybe the guy who sold me it knew it had a knock and put thicker oil in or something but if anybody has had this happen it would be greatly appreciated if i could get some help on this, thank you
