hi everybody, i'm new to modding my car and i only know a few things about it, my SES light went on about a month ago, so i had the code read and my mechanic said i need a new EGR valve, but he said it won't affect performance, it just can't pass inspection without it, i was just wondering if there was any other options i have before spending $400 for him to put a new one on.
Also i just got all new 3' exhaust system w/ flowmaster 40 series, and a couple of days after that the SES light comes on more often and massive amouts of exhaust is coming into my car, but its not visible, i feel high whenever i get out of my car, could that be from the EGR valve or did my other mechanic miss a weld?
Just 2 more questions When my rpm's get up to 3500-4000 the muffler sounds very poppy, would headers fix that?
Last one i recently changed my oil and i used 10-30 quakerstate oil and after driving for a long time when i come to a complete stop my oil pressure gauge bottoms out and the check gauge light comes on. my grandpa said since i have over 172,000 miles that i should use a much thicker oil like 10-50, i just want to know what oil would work best and would synthetic work better?
Thanks in advance and i hope i'm not an annoyance for asking to many question
:D
