Is your check engine light on? Does it idle like crap and run like crap under load? How many miles on the motor?

When driving does it seem to chug or lose power every now and then?

To me it sounds like the problems most of use have had with the 4.2 at some time are another, IF your laws allow and it will still past inspection DO the Nutter-Bypass, mine runs Very good now!
