sorry for not mentioning that i had the tank dropped and the in tank pump replaced.
also replaced the inline filter. this plus all the other listed items have not made any difference. also had a muffler shop chek out the two cats. i am totally lost.
i also tried in tank fuel injector cleaner. iam thinking about replacing the maf or the throttle position sensor next. what do you think.
i keep getting a gateway timedout when i send my response to you
ill try again
fuel pressure was tested prior to the in tank pump replacement and no change occured.
the cats inlet pipe were cut open an a visual inspection was accomp. by the muffler shop. said they looked ok.
a snapon computer was connected to the system prior to there driving it an nothing registered
where are the injectors and fuel regulator located on this engine. under the intake manifold?
also changed the iginition control module.
thanks for your help
i will have the cats tested with a back pressure check and replace the maf. if i ever get it fixed i will let you know.
