MPG Dropped Since Accident??? HELP!!

[Papa Rick]

Alignment is good, had the 3 axle alignment done after the accident. Have not had any noticeable smoke coming out of my stacks, but will keep an eye on this.

I really do appreciate the suggestions and advice and encourage more of them as sooner (hopefully much sooner) or later something will show up.

Would you go ahead and pay $450.00 to get the overhead ran since everything checked out on the dyno test, or wait?

Should I have black smoke coming out of my stack? It only happens after I coast down a hill then stomp on the pedal or right after I shift then hit the pedal again.

I'm not sure if I recall black smoke coming out?

Well, I was going to say your EGR valve was possibly starting to go.......but you don't have one.


Did you have an overhead done on your engine?

I would agree that it will cost some on mpg, but never heard of it doing this much damage.

Heck I figured it up and for the past 2 weeks it has cost me $700.00 more in fuel??????

ANY SUGGESTIONS ANYONE????

Get rid of the CAT motor. Nothing but a fuel hog.
