Something is not working. It's time to not assume that which is new is good.
First off, with numbers that high I would seriously question the cat. You can point one of those infrared thermometers (Radioshack has em but I'd try to borrow one, they are about $50) at the cat and I believe it should be around 50-100 degrees hotter on the outlet than on the inlet. If the inlet/outlet temps are the same, it is bad. Just curious, but what do your HC's look like? Are they high but passing? If you aren't throwing a code 71 then likely the egr is working correctly. Bad timing, plugs, and such will raise numbers, but they should not cause a failure of that magnitude. Frank |
frank the cat is 5 days old lol im thinkin thats not it right now im down to timing (which will e checked tomorrow) and c4

by the way the other readings are just fine up and down a point or 2 ( which i thought might lead me in one direction or another but i cant make heads or tails of it)
