Lenny,
Thanks for your input. Here's a few periods, please use them ........ It's hard to read what your saying without them; spell check wouldn't hurt either.
From what I understand your saying that if you get a code for a miss-fire on cylinder #4 at idle your saying: replace the lower intake, clean the intake valves, and replace the EGR and tube gasket, all for $331.00.
Thanks
