You are right, it is a quad port. Was just out testing items from your earlier response when I came in to find your additional information...thank you!!! Bouncing back and forth between your response and the tech pages i was able to find why the car got worse after the shop worked on it. The EGR live test failed and I found that they had flipped the cap on the modulator and thereby had it plumbed backwards (P and Q going to the wrong spots). EGR now passing live test, woohoo! Found it odd that l had to spin the wheel on a 1993 to perform tests...does that make any sense? Started to think maybe a previous owner put an ECU in from a different year? Oh, and you asked for a pic of the cats relationship to the header...it’s as close as it could be(3-5” from the header flange) And it is a brand new 3 way cat specified for the vehicle.
