hey everyone! Here is the situation. I have a 1999 Isuzu Rodeo LS with about 90,000 miles on it. I havent had too much problems with it, except for the check engine light ALWAYS being on, until recently. Over the past two months, when I start my car, it will die immediately. I then have to restart it a few times and even rev the engine to keep it running. Then, the past two weeks, it has actually died on me while I am driving it on the road. I then have to pull over, put it in park and restart it. I had someone look at it and they said that I have a leak in my vacuum system. I was wondering if anyone else has had this problem or something similar and if this sounds like it is the problem. I also wanted to know how serious this is and about how much this costs to fix. I just got the car in Nov so Im wondering if it is even worth it to fix. I like the car and havent really had any other problems!! Also, Im a girl so please make it understandable!!!!! Thanks so much!!!!
