When I am accelerating my engine will sometimes hesitate and all of a sudden start going again. Also, the check engine light comes on. And when idling, the engine will sometimes go very low in rpms and then shoot up to about 1500 and then back down to normal. It is like the engine is about to die but gets started again.
This has happened before after driving through deep puddles. The last two times this happened, I changed the air filter, put in fuel injection cleaner and the problem eventually went away. I am going to put in fuel injection cleaner tonight but I was wondering what it is that makes my XJ do this.
I was thinking maybe that excess water was making some component not give enough spark to burn the fuel. My Chiltons book diagnosed the problem as a faulty fuel pump, but I was wondering how water could affect that. It isnt like I was driving through a river. I was just driving in a wet mountain pass while it was raining heavily when this problem came back to haunt me.
Does anybody know what is going on?
Thanks for any suggestions.
