It wasn't a bad valve...............Read on.....

Well, my previous message was about my truck running really rough and black smoke from the exhaust. After some trouble shooting, I found out it was a bad MAP sensor and a bad 02 sensor. For some reason the SES light doesn't come on. If I unplug TP sensor or EGR it does. Go figure......

 

I used some of that Seafoam in the begining and it made it run even worse. But really it cleaned the top end so good it fouled the plugs. After the plug were changed it ran alot smoother. After new sensor's it runs like new. Knock on wood. Any way I will drive it around for the next week and update you if any thing happens.

 

Thanks,
