guys ask lang ako if this is normal, kasi pag bago start yung kotse parang palyado makina, hindi naman sha namamatay...pero pag tumakbo na ok na sha, maganda hatak. pag naka idle naman sha na mainit na makina parang sumisinok yung engine. 93 xe bigbody pala yung kotse na tinutukoy ko so 1.3 engine sha, any suggestions?napa tune up ko na toh, napalitan spark plug and filter.na change oil ko na din..ano kaya problem?
