2001 Lexus IS300 Question: front engine seal replacement? spark plug firing sensor? dont know whats wrong?
driving around town this week the engine started running rough when at stoplights and idling. It was fine when driving and accelerating then yesterday when I got a stop light it felt like the engine wanted to die and suddenly the check engine light came on. I had thought I needed to get spark plugs replaced but I had the code read and the guy told me it was maybe the front engine seal leaking because there's oil all over the timing belt and maybe getting on the spark plugs causing misfires. Or maybe its some kind of spark plug sensor... I don't know... Has anyone had problems like this before? Please help..... My husband and I are worried this is going to cost a lot of money...Also the air conditioner has been giving me a few problems....I dont want to but maybe its time to trade it in for another car... :( - sshulsky
What is happening is there is a seal in front of your engine that is almost twelve years old and has sprung a leak...It is now leaking all over your timing belt and cam and crank sensor causing a misfire...What needs to be done is a maintenance issue...have your timing belt, water pump and seals replaced along with your tensioner and pulley(s). The air conditioning can wait a few more months. - your.mechanic
