Reed44 Posted August 18, 2009 Report Share Posted August 18, 2009 my bravada is runing like poop and I can't figure out what it is. its bogging out bad and acting like its misfiring. its not consistent and doesn't do it all the time but most the time. I have done plugs wires, cap, rotor, new fuel pump last year, new intake gasket last year, high flow cat today. I have put a scanner on it and I don't get any missfires even when I spary the wires and cap with water. I put a fuel pressure gauge on it to see if it was leaking maybe thorugh the spider injectors but it holds pressure. I don't know what else to do. im trying to get rid of it but kinda can't with it like this Quote Link to comment Share on other sites More sharing options...
AJ Posted August 18, 2009 Report Share Posted August 18, 2009 remove the EGR valve and check it for carbon build up. Quote Link to comment Share on other sites More sharing options...

AJ Posted August 19, 2009 Report Share Posted August 19, 2009 if you look at some AC Delco plugs they say NGK on the metal base. NGK makes all AC Delco's plugs. Quote Link to comment Share on other sites More sharing options...
Cordell Posted August 19, 2009 Report Share Posted August 19, 2009 If the plugs are new I wouldn't worry about brand, but hopefully you checked them over as you installed them. I've had to send plenty of spark plugs back because of a defect or crack. Quote Link to comment Share on other sites More sharing options...

Um no..they make all the newer plugs(iridium's mainly) go grab a r45ts delco plug and a autolite 24. same numbers and lettering on the metal bases.
