Hey guys, Help!! Car starts up just fine, but after about 10 minutes of driving, when engine reaches temperature of about 160 degrees, SES light pops on, and then the engine starts hesitating, especially when I take my foot off the gas. Light usually comes on when car is stopped at a red light. What could it be? If it was a clogged fuel line, or air filter, wouldn't it run bad from the start? It has something to do with reaching temperature....any ideas? Thanks!!!!!!!!!
