hi i am shannon i will help on this issue
the tune up sound like a good idea
i would add a new ignition coil to that too
as far as the cat converter being blocked you can test for that with a engine vacuum gauge
i will post a video and a vacuum chart.
hear is an inexpensive gauge
i hope this answer,s all your questions. if not please post back any question on this issue you need
I appreciate your informative and timely reponse. your suggestion about testing engine vacuum to determine the condition of the exhaust system may save me $750 bucks. i even think i have a vacuum testing gauge. What do i need to do to insure that you are paid the $59 bucks.
i am thinking that if i have additional questions regarding this same issue, i can continue to post those questions using this procedure. thank you again.
I am going to continue to pester you for information, if i can get it for the fee i have already paid ;-)
i did a compression test on the engine and came up with 110 PSI for all the cylinders, i was tickled. i have done some research and cannot find an actual specification for that. I think the fact that all the readings were exactly the same says a lot. anywho, if you can give me the actual specifications for a nominal compression test for the 4.9 liter ford 6 cylinder, i would be thrilled
i am thanking you ahead of time
there has been nothing new to reporti have followed your directions and suggestions and the truck project is kind of at a standstill right now.i can only spend so much time and money trying to restore my old pick'em up truckythank you again
