Car isnt runnin 100%. Changed my plugs to see if that would help and saw my two under boot not coil plugs have an orange ring on them. Anyone know what the cause of this would be, bad timing maybe?
If you are running lean, you would notice on your wideband. I don't think they look like they are burning abnormally. Could you give a better description of the problem?
Normal wear and tear. That appears on every car I have seen. Looks like rust. Are you throwing any codes? Most common issue for bad idle is vacuum leaks, spark plugs, and dirty maf.
That does sound like an EGR or vacuum problem. I would check for vacuum leaks first and if necessary replace any lines with silicone instead of rubber. EGR valves are not cheap unless you buy it used, but that would be a waste to buy a used item like that. I bought the Canadian EGR from rockauto.com and it was not cheap but it is a much better design.
New Maf on, gonna replace the egr with the candaian when i can, prob need to replace the vacuum lines to. Thanks guys. Oh yeah, just put ngk iridims in, factory gap, don't want to mess up the tip, have gapped them before though.
