i have a 91 integra LS IT HAS 193000 MILES ON IT AND it runs like champ.i recently bought some spark plug wires for it and they dont fit.The parts store say it calls for those and my mechanic and i seem to disagree.Anyone having those types of problems?Also one night when i got home i noticed some bubbling noises coming from the engine but my gauge always reads a normal temperature. Any guesses?
