Does anybody know what the difference is between the 4 cyl and 6 cyl EGR valves? My idle is SUPER low at idle (250rpms warm) and i cleaned my IACV, and the port to the EGR valve, but it still sits that low most of the time. Anyways, i went to buy i new one online and clicked the cheapest EGR valve i saw, read the details and noticed it was for a V6. So i find a 4Cyl one and i cant find any that are under bout 125.00 while the V6 i found as low as 65.00. and they both look the same! If anybody has any imput on my idle problem or my actual question it'd be very helpful, Thanks!
